The invention discloses a structure of an automatic round pin typewriter. The structure comprises a turntable part, a feeding part, a typewriting part and a discharging part, wherein the feeding part, the typewriting part and the discharging part are distributed around the turntable part. The rotating disc part comprises a rotating disc and a floating jig arranged on the rotating disc, the floating jig comprises a floating mechanism installed on the edge of the rotating disc and a floating jig plate arranged on the floating mechanism, and the floating jig plate is provided with a round pin positioning hole. The typewriting part comprises a typewriting jig mechanism capable of ascending and descending and a lower collision block located below the typewriting jig mechanism, the typewriting jig mechanism comprises a typewriting jig head and a jacking pin piece, and the bottom end of the jacking pin piece is lower than the typewriting jig head. Before the round pin in the floating jig plate is typewritten, the pin piece is jacked and pressed to enable the floating jig plate to descend relative to the round pin; after the round pin is typewritten, the floating jig plate drives the round pin to ascend, so that the round pin is separated from the lower collision block. Therefore, when the turntable rotates, the bottom end of the round pin does not rub with the lower collision block, so that the round pin can be smoothly transferred.

Description

Technical Field

[0001] The invention relates to the field of product processing, in particular to a round pin typing device. Background Art

[0002] To type on one end of a round pin, the round pin needs to be erected, the typing jig needs to be lowered, and the top end of the round pin needs to be typed. In order to withstand the impact of the typing jig, a support block is required at the bottom of the round pin.

[0003] For typing with round pins one by one, a worker or robot positions the round pin under a typing jig, which is supported by a support block. The typing jig descends to perform typing. After typing is completed, the typing jig rises and resets, and the worker or robot removes the round pin from between the support block and the typing jig.

[0004] For continuous typing of batch round pins, the batch round pins are transported forward by the conveyor line. When passing under the typing jig, the typing jig descends for typing. After typing is completed, the conveyor line continues to transport the round pins forward to the predetermined workstation for unloading. In this process, the conveyor line needs to continuously transport the round pins forward. However, during typing, the bottom end of the round pin needs to be supported by a support block. After typing is completed, the bottom end of the round pin moving forward will produce friction with the support block. Summary of the invention

[0005] The technical problem solved by the present invention is as follows: for continuous typing of batches of round pins, the conveyor line needs to continuously convey the round pins forward. However, during typing, the bottom end of the round pin needs to be supported by a support block. After typing is completed, the bottom end of the round pin moving forward will generate friction with the support block.

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions: the structure of the automatic round pin typewriter includes a turntable part, a feeding part, a typing part and a unloading part distributed around the turntable part, the turntable part includes a turntable, a floating fixture arranged on the turntable, and the floating fixture includes a floating mechanism installed on the edge of the turntable and a floating fixture plate installed on the floating mechanism;

[0007] The floating mechanism comprises a floating mechanism fixing plate fixed on the edge of the turntable, and a floating mechanism lifting seat movably matched with the floating mechanism fixing plate through a floating mechanism guide column, a telescopic spring is sleeved on the floating mechanism guide column, and the telescopic spring is located between the floating mechanism fixing plate and the floating mechanism lifting seat;

[0008] The floating fixture plate is installed on the floating mechanism lifting seat, and the floating fixture plate is provided with a round pin positioning hole, and the round pin can be closely matched with the round pin positioning hole. The floating mechanism fixing plate and the floating mechanism lifting seat are provided with a round pin giving way structure for the round pin to pass through, and the round pin protrudes downward from the floating mechanism lifting seat;

[0009] The typing part comprises a typing jig mechanism connected to the boost cylinder and a lower collision block located below the typing jig mechanism. The typing jig mechanism comprises a typing jig head and a top pressing pin, and the bottom end of the top pressing pin is lower than the typing jig head.

[0010] The feeding part provides a round pin to the turntable part, and the round pin is vertically inserted into the round pin positioning hole, and the top of the round pin is flush with the top surface of the floating jig plate. Under the rotation of the turntable, the round pin comes to the typing part, the typing jig head is located above the round pin, and the lower collision block is located below the round pin. The booster cylinder drives the typing jig mechanism to descend, and the typing jig head and the top pressure pin component descend synchronously. Since the bottom end of the top pressure pin component is lower than the typing jig head, the top pressure pin component first contacts the floating jig plate. The top pressure pin component drives the floating jig plate to descend, and the floating mechanism lifting seat descends relative to the floating mechanism fixed plate. The telescopic spring is compressed and accumulates elastic potential energy. The round pin descends with the floating jig plate, and its bottom end contacts the lower collision block. The round pin no longer descends, and the floating jig plate and the floating mechanism lifting seat fixed together continue to descend. The round pin protrudes upward from the floating jig plate, and the typing jig head contacts the top surface of the round pin to type on the top surface of the round pin. After completion, the typing jig mechanism rises and resets, the telescopic spring releases elastic potential energy, pushes the floating mechanism lifting seat to rise relative to the floating mechanism fixed plate, and the floating jig plate and the round pin therein rise synchronously, the bottom end of the round pin moves upward away from the lower collision block, and has no contact with the lower collision block, the top of the round pin has an upper and lower gap with the typing jig head, and the top of the round pin is lower than the top pressing pin after the rise and reset. After that, the turntable rotates, and the typing-finished round pin and its floating jig rotate accordingly, and come to the unloading part, which unloads the typing-finished round pin.

[0011] The present invention makes the floating jig plate descend relative to the round pin before typing the round pin; after the typing of the round pin is completed, the floating jig plate rises with the round pin to make the round pin separate from the lower collision block. In this way, when the turntable rotates, the bottom end of the round pin will not rub against the lower collision block, which is conducive to the smooth transportation of the round pin.

[0012] As an option, an annular groove is provided on the inner wall of the round pin positioning hole, and a rubber ring is embedded in the annular groove, so that the round pin and the round pin positioning hole can be closely matched, and the round pin will not automatically fall relative to the round pin positioning hole and can be maintained in the round pin positioning hole.

[0013] The feeding part includes a plate pusher, a straight vibration track connected to the plate pusher, and a round pin assembly mechanism located beside the straight vibration track. The round pin assembly mechanism includes a round pin assembly mechanism mechanical arm, a round pin assembly mechanism lifting cylinder connected to the round pin assembly mechanism mechanical arm, a round pin assembly magnet mounting plate connected to the round pin assembly mechanism lifting cylinder, and a round pin assembly electromagnet installed on the round pin assembly magnet mounting plate. The output track of the plate pusher is tilted, and there is a drop between the output end of the output track and the entrance end (i.e., the opening end) of the straight vibration track. After the round pins in a horizontal state move out of the output track, due to the drop, the round pins stand upright in the straight vibration track and are parallel to the round pins that have stood upright in the straight vibration track, and move forward together. The straight vibration track is slightly tilted. Under the action of vibration, a row of upright round pins move forward together along the straight vibration track to the round pin assembly mechanism. After the round pin assembly electromagnet adsorbs the round pin, the round pin rises under the drive of the round pin assembly mechanism lifting cylinder, and the round pin is translated to the top of the round pin positioning hole on the floating fixture plate under the drive of the round pin assembly mechanism mechanical arm. Driven by the round pin assembly mechanism lifting cylinder, the round pin descends and is inserted into the round pin positioning hole. The top of the round pin is flush with the top surface of the floating fixture plate. After the round pin assembly electromagnet loses power, it is reset to the straight vibration track to transport the next round pin.

[0014] The direct vibration track includes a pair of track vertical plates constituting the track, and the pair of track vertical plates are installed on the direct vibration track base. The end of the direct vibration track connected with the push plate machine is open, and the other end of the direct vibration track is closed. The open end of the direct vibration track is connected with the output track of the push plate machine, and the round pin in the direct vibration track moves forward and stops at the closed end of the direct vibration track. The round pin is assembled into an electromagnet to obtain the round pin at the closed end.

[0015] The floating mechanism lifting seat comprises an upper plate installed on the top of the floating mechanism guide column, a lower plate installed on the bottom of the floating mechanism guide column, a guide sleeve installed on the floating mechanism fixed plate, the floating mechanism guide column cooperates with the guide sleeve, the telescopic spring sleeve is arranged on the floating mechanism guide column and is located between the upper plate and the floating mechanism fixed plate, under the elastic force of the telescopic spring, the lower plate can be against the bottom of the guide sleeve. When the lower plate is against the bottom of the guide sleeve, the floating mechanism lifting seat rises to the limit position.

[0016] The boost cylinder and the lower collision block are installed on the typing jig frame. A slot-shaped photoelectric sensor is installed on the typing jig frame. The slot-shaped photoelectric sensor is located next to the lower collision block. A sensor matching induction sheet is installed at the bottom of the floating mechanism lifting seat. The sensor matching induction sheet is used in conjunction with the slot-shaped photoelectric sensor. The sensor matching induction sheet rises and falls with the floating mechanism lifting seat. The slot-shaped photoelectric sensor can obtain the lifting amount of the floating mechanism lifting seat, and then judge the lifting amount of the typing jig mechanism, and then judge the depth of the typing jig mechanism typing on the top surface of the round pin, providing information for the control of the typing depth of the top surface of the round pin.

[0017] The unloading part includes an unloading robot arm, an unloading lifting cylinder connected to the unloading robot arm, an unloading magnet mounting plate connected to the unloading lifting cylinder, and an unloading electromagnet mounted on the unloading magnet mounting plate. The turntable rotates, and the round pin that has been typed comes to the unloading part. After the unloading electromagnet adsorbs the round pin, the round pin rises and detaches from the round pin positioning hole of the floating fixture plate under the drive of the unloading lifting cylinder. Driven by the unloading robot arm, the round pin translates to the top of the unloading guide groove. Driven by the unloading lifting cylinder, the round pin descends, the unloading electromagnet loses power, the round pin falls into the unloading guide groove, and the unloading electromagnet resets to the turntable to unload the next round pin.

The floating fixture plate 121 is installed on the floating mechanism lifting seat. The floating fixture plate is provided with a round pin positioning hole. The round pin can be closely matched with the round pin positioning hole. The floating mechanism fixing plate and the floating mechanism lifting seat are provided with a round pin giving way structure for the round pin to pass through. The round pin protrudes downward from the floating mechanism lifting seat.

[0039] like Figure 5 The direct vibration track 50 includes a pair of track uprights 51 constituting the track, and the pair of track uprights are installed on the direct vibration track base 52. One end of the direct vibration track connected to the push plate machine 40 is open, and the other end of the direct vibration track is closed.

[0040] like Figure 7 The floating mechanism lifting seat includes an upper plate 125 installed on the top of the floating mechanism guide column 123, and a lower plate 126 installed on the bottom of the floating mechanism guide column. A guide sleeve 127 is installed on the floating mechanism fixed plate 122, and the floating mechanism guide column cooperates with the guide sleeve. The telescopic spring 124 is sleeved on the floating mechanism guide column and is located between the upper plate and the floating mechanism fixed plate. Under the elastic force of the telescopic spring, the lower plate 126 can be against the bottom end of the guide sleeve.

[0041] Combination Figure 8 , Figure 7 The boost cylinder 21 and the lower collision block 23 are installed on the typing jig frame 24. A groove-shaped photoelectric sensor 25 is installed on the typing jig frame. The groove-shaped photoelectric sensor is located next to the lower collision block. A sensor matching induction sheet 26 is installed at the bottom position of the floating mechanism lifting seat. The sensor matching induction sheet is used in conjunction with the groove-shaped photoelectric sensor.

[0042] like Fig.10 The unloading part 30 includes an unloading robot arm 31, an unloading lifting cylinder 32 connected to the unloading robot arm, an unloading magnet mounting plate 33 connected to the unloading lifting cylinder, and an unloading electromagnet 34 mounted on the unloading magnet mounting plate.

[0043] refer to Figure 4 The output track 41 of the push plate machine 40 is tilted, and there is a drop between the output end of the output track and the open end of the direct vibration track 50. After the horizontal round pin moves out of the output track 41, due to the drop, the round pin 90 stands upright in the direct vibration track 50 and is parallel to the round pins that have stood upright in the direct vibration track, and moves forward together. The direct vibration track 50 is slightly tilted. Under the action of vibration, a row of upright round pins moves forward together along the direct vibration track and stops at the closed end of the direct vibration track. The round pin assembly electromagnet 64 of the round pin assembly mechanism 60 obtains the round pin 90 at the closed end.

[0044] After the round pin assembly electromagnet 64 adsorbs the round pin, the round pin rises under the drive of the round pin assembly mechanism lifting cylinder 62, and the round pin is translated to the top of the round pin positioning hole on the floating fixture plate 121 under the drive of the round pin assembly mechanism lifting cylinder 62. The round pin descends and is inserted into the round pin positioning hole. The top of the round pin is flush with the top surface of the floating fixture plate 121. After the round pin assembly electromagnet 64 loses power, it is reset to the straight vibration track 50 to transport the next round pin. An annular groove is provided on the inner wall of the round pin positioning hole, and a rubber ring is embedded in the annular groove. In this way, the round pin and the round pin positioning hole are closely matched, and the round pin will not automatically fall relative to the round pin positioning hole and can be kept in the round pin positioning hole.

[0045] Under the rotation of the turntable 11, the round pin 90 comes to the typing part 20, the typing jig head 221 is located above the round pin, and the lower collision block 23 is located below the round pin. The booster cylinder 21 drives the typing jig mechanism 22 to descend, and the typing jig head 221 and the top pressing pin 222 descend synchronously. Since the bottom end of the top pressing pin is lower than the typing jig head, the top pressing pin 222 first abuts against the floating jig plate 121. The top pressing pin drives the floating jig plate to descend, and the floating mechanism lifting seat descends relative to the floating mechanism fixed plate 122, and the telescopic spring 124 is compressed to accumulate elastic potential energy. The round pin descends with the floating jig plate 121, and its bottom end abuts against the lower collision block 23, and the round pin no longer descends, while the floating jig plate 121 and the floating mechanism lifting seat fixed together continue to descend, and the round pin protrudes upward from the floating jig plate 121, and the typing jig head 221 contacts the top surface of the round pin to type on the top surface of the round pin. The sensor-matching induction sheet 26 rises and falls with the floating mechanism lifting seat, and the groove-shaped photoelectric sensor 25 can obtain the lifting amount of the floating mechanism lifting seat, and then determine the lifting amount of the typing jig mechanism 22, and then determine the depth of typing of the top surface of the round pin by the typing jig mechanism 22, providing information for controlling the typing depth of the top surface of the round pin.

[0046] After the round pin is typed, the typing jig mechanism 22 rises and resets, the telescopic spring 124 releases elastic potential energy, pushes the floating mechanism lifting seat to rise relative to the floating mechanism fixed plate 122, and the floating jig plate 121 and the round pin therein rise synchronously, the bottom end of the round pin moves upward away from the lower collision block 23, and has no contact with the lower collision block, the top end of the round pin has a gap between the typing jig head 221 and the top end of the round pin is lower than the top pressing pin 222 after the rise and reset. After that, the turntable 11 rotates, and the typed round pin and its floating jig 12 rotate accordingly, and come to the unloading part 30.

[0047] After the unloading electromagnet 34 of the unloading part 30 absorbs the round pin, the round pin 90 rises under the drive of the unloading lifting cylinder 32 and detaches from the round pin positioning hole of the floating fixture plate 121. Under the drive of the unloading mechanical arm 31, the round pin is translated to the top of the unloading guide groove 35. Under the drive of the unloading lifting cylinder 32, the round pin descends, the unloading electromagnet 34 loses power, the round pin falls into the unloading guide groove 35, and the unloading electromagnet is reset to the turntable 11 to unload the next round pin.
