Technical Field

[0001] This application relates to the technical field of screw processing, and in particular to a screw sleeve pellet tray. Background Art

[0002] Screw sleeve insulating pellets play various roles in the electrical system, such as insulation protection, preventing current loss, reducing galvanic corrosion, and reducing stray current interference. They are an important part of the electrical system.

[0003] In the prior art, the insulating pellets need to be sleeved on the neck of the screw. The screw is conveyed to the tray along the screw feeding unit, and the insulating pellets are conveyed to the tray along the insulating pellet feeding unit. The tray is located at the output ends of the screw feeding unit and the insulating pellet feeding unit. Subsequently, the neck of the screw is squeezed into the central hole of the insulating pellet through the pellet sleeving device, so that the end of the screw fits with the insulating pellet, thereby realizing the screw pellet sleeving process. After the screw pellet sleeving is completed, the operator manually clamps and takes out the sleeved screw from the tray for collection.

[0004] The above-mentioned feeding method of manually clamping the sleeved screw by the operator has a slow feeding speed, high labor cost, time-consuming and laborious, and results in low production efficiency. Summary of the Invention

[0005] In order to help solve the problem of the feeding method of manually clamping the sleeved screw by the operator, which is time-consuming and laborious and results in low production efficiency, a screw sleeve pellet tray provided by this application adopts the following technical solutions: It includes a base, a tray is rotatably connected to the base, a driving unit for driving the tray to rotate is provided on the base, a limiting unit for simultaneously limiting a plurality of pairs of screws and insulating pellets is provided on the tray, and a feeding unit for releasing the limit of the limiting unit is provided on the base.

[0006] Through the above technical solutions, the limiting unit is used to simultaneously limit a plurality of pairs of screws and insulating pellets on the tray, reducing the possibility of the positions of the screws and insulating pellets shifting. When the screw pellet sleeving is completed, the driving unit is started to drive the tray to rotate, so that the limiting unit where the sleeved screw is placed rotates to the discharge end of the tray, and the feeding unit is used to release the limit of the limiting unit, thereby realizing the automatic feeding of the sleeved screw, reducing the labor cost, saving time and effort, and improving the feeding speed and production efficiency of the screw pellet sleeving.

[0007] In a specific feasible implementation, the limiting unit includes a mounting groove formed on the surface of the tray facing away from the base. A limiting groove matching the insulating particles is formed at the bottom of the mounting groove. The limiting groove is correspondingly arranged with the output end of the insulating particle feeding unit. The insulating particles output from the insulating particle feeding unit are sequentially placed in the limiting grooves of a plurality of limiting units.

[0011] In a specific feasible implementation, the reset assembly includes a first spring and a second spring. The first clamping block and the second clamping block are located between the first spring and the second spring. The two ends of the first spring are respectively connected to the groove wall of the mounting groove and the first clamping block. The two ends of the second spring are respectively connected to the groove wall of the mounting groove and the second clamping block.

[0012] Through the above technical solution, when the conical top rod extends under the drive of the telescopic cylinder and is inserted into the top hole, the first spring is pressed tightly between the first clamping block and the groove wall of the installation groove, and the second spring is pressed tightly between the second clamping block and the groove wall of the installation groove. The first clamping block and the second clamping block are in an open state, facilitating the feeding of the screws after the sleeving is completed; when the conical top rod retracts under the drive of the telescopic cylinder, the first clamping block resets under the action of the first spring, and the second clamping block resets under the action of the second spring. At this time, the first clamping block and the second clamping block are in a closed state.

[0013] In a specific feasible implementation, a cover plate is provided on the material tray, and both the first clamping block and the second clamping block are located between the cover plate and the bottom of the installation groove.

[0014] Through the above technical solution, the cover plate reduces the interference of external equipment on the first clamping block and the second clamping block, reduces the possibility of debris, dust, etc. entering the installation groove, and plays a protective role.

Detailed Embodiment

[0032] The following is combined with the attachedFigures 1-5 Further detailed description of the present application is provided as follows.

[0033] An embodiment of the present application discloses a screw sleeve granule tray.

[0034] Referring to Figure 1 and Figure 2 , the screw sleeve granule tray includes a base 1, a tray 2 is rotatably connected to the base 1, a driving unit for driving the rotation of the tray 2 is provided on the base 1, a plurality of limiting units 3 for simultaneously limiting screws and insulating granules are provided on the tray 2, and a blanking unit 4 for releasing the limitation of the limiting unit 3 is provided on the base 1. In the embodiment of the present application, the number of the limiting units 3 is eight and they are arranged in a circumferential array along the tray 2. The eight limiting units 3 are evenly distributed on the circumference of the tray 2, which helps to achieve the overall balance and stability of the tray 2, reduce the vibration or shaking of the tray 2 caused by the center of gravity offset, and improve the overall stability and safety.

[0035] Referring to Figure 1 and Figure 2 , a receiving pipe 25 perpendicular to the base 1 is installed on the base 1, and the pipe orifice of the receiving pipe 25 is arranged at the discharging end of the tray 2. A receiving bucket for receiving the sleeved screws can be provided at the output end of the receiving pipe 25. The sleeved screws fall into the receiving bucket after being collected by the receiving pipe 25, so as to facilitate the centralized storage of the sleeved screws. In the embodiment of the present application, the base 1 is inclined, which is convenient for the blanking unit 4 to release the limitation on the limiting unit 3, and the sleeved screws fall into the receiving pipe 25 under the action of gravity, improving the blanking efficiency of the sleeving device.

[0036] Referring to Figure 2 and Figure 3 , the driving unit includes a driving motor 20 provided on the base 1, a speed reducer 21 is provided on the base 1, a first pulley 22 is installed at the input end of the speed reducer 21, a second pulley 23 is installed at the output end of the driving motor 20, a belt 24 is tightly wound between the first pulley 22 and the second pulley 23, and the tray 2 is arranged at the output end of the speed reducer 21.

[0037] Therefore, when the driving motor 20 is started, the second pulley 23 is driven to rotate, and the first pulley 22 at the input end of the speed reducer 21 is driven to rotate synchronously through the belt 24. Since the tray 2 is arranged at the output end of the speed reducer 21, the rotation speed of the tray 2 can be controlled, and the tray 2 at the output end of the speed reducer 21 is driven to rotate, so that the position of the limiting unit 3 on the tray 2 can be changed. The main function of the speed reducer 21 is to reduce the rotation speed at the input end and increase the torque at the output end, so that the driving motor 20 works at a lower rotation speed and provides sufficient torque to drive the rotation of the tray 2. The belt 24 transmission can provide a stable operation effect, reduce vibration and impact, and improve the rotation stability of the tray 2.

[0038] Referring to Figure 2 and Figure 4 , the limiting unit 3 includes a mounting groove 5 formed on the surface of the tray 2 facing away from the base 1. A limiting groove 6 matching the size of the insulating particles is formed at the bottom of the mounting groove 5. The limiting groove 6 is correspondingly arranged at the output end of the insulating particle feeding unit. The insulating particles output from the insulating particle feeding unit are successively placed in the limiting grooves 6 of a plurality of limiting units 3. A first clamping block 7 and a second clamping block 8 are rotatably connected in the mounting groove 5. Arc-shaped grooves 9 are respectively formed oppositely on the first clamping block 7 and the second clamping block 8. The two arc-shaped grooves 9 are spliced to form a limiting hole 10. The limiting hole 10 is coaxially arranged with the limiting groove 6. The screws output from the screw feeding unit are successively placed in the limiting holes 10 of the limiting unit 3. In the embodiment of the present application, the insulating particle feeding unit may include a vibrating disk arranged on the base 1. The output end of the vibrating disk is connected with a screw feeding track. The tray 2 is located at the output end of the screw feeding track. A plurality of screws are successively placed in the screw feeding track. In the embodiment of the present application, the insulating particle feeding unit has the same structure as the screw feeding unit.

[0039] Therefore, the limiting groove 6 positions the insulating particles, and the limiting hole 10 positions the screws, reducing the possibility of the screws and insulating particles shifting, improving the stability of the placement of the screws and insulating particles. Since the limiting groove 6 and the limiting hole 10 are coaxially arranged, the screws can accurately pass through the insulating particles, improving the accuracy of screwing on the particles.

[0040] Referring to Figure 2 and Figure 5 , the blanking unit 4 includes a telescopic cylinder 11 arranged on the base 1. A conical ejector rod 12 matching the size of the top hole 15 is provided at the output end of the telescopic cylinder 11. A first top groove 13 is formed on the surface of the first clamping block 7 facing the second clamping block 8. A second top groove 14 is formed on the surface of the second clamping block 8 facing the first clamping block 7. The first top groove 13 and the second top groove 14 have the same size and shape. The first top groove 13 and the second top groove 14 are spliced to form a top hole 15. The conical ejector rod 12 passes through the tray 2 and is inserted into the top hole 15. A reset assembly for driving the first clamping block 7 and the second clamping block 8 to reset is provided on the tray 2.

[0041] Therefore, when the telescopic cylinder 11 is started, the conical ejector rod 12 at the output end of the telescopic cylinder 11 extends and is inserted into the top hole 15, thereby driving the first clamping block 7 and the second clamping block 8 to open, and the first clamping block 7 and the second clamping block 8 release the restriction on the screwed-on screws, realizing the automatic blanking of the screwed-on screws; the conical ejector rod 12 retracts under the drive of the telescopic cylinder 11, and the first clamping block 7 and the second clamping block 8 reset under the action of the reset assembly, thereby driving the first clamping block 7 and the second clamping block 8 to close.

[0042] Referring to Figure 2 and Figure 5, the reset assembly includes a first spring 16 and a second spring 17. The first clamping block 7 and the second clamping block 8 are located between the first spring 16 and the second spring 17. The two ends of the first spring 16 are respectively connected to the groove wall of the installation groove 5 and the first clamping block 7, and the two ends of the second spring 17 are respectively connected to the groove wall of the installation groove 5 and the second clamping block 8.

[0043] Therefore, when the conical top rod 12 extends under the drive of the telescopic cylinder 11 and is inserted into the top hole 15, the first spring 16 is pressed tightly between the first clamping block 7 and the groove wall of the installation groove 5, and the second spring 17 is pressed tightly between the second clamping block 8 and the groove wall of the installation groove 5. The first clamping block 7 and the second clamping block 8 are in an open state, facilitating the feeding of the screws after the sleeving is completed; when the conical top rod 12 retracts under the drive of the telescopic cylinder 11, the first clamping block 7 is reset under the action of the first spring 16, and the second clamping block 8 is reset under the action of the second spring 17. At this time, the first clamping block 7 and the second clamping block 8 are in a closed state.

[0044] Refer to Figure 2 and Figure 5 , a cover plate 18 is arranged on the material tray 2. Both the first clamping block 7 and the second clamping block 8 are located between the cover plate 18 and the bottom of the installation groove 5. The cover plate 18 reduces the interference of external equipment on the first clamping block 7 and the second clamping block 8, and reduces the possibility of debris, dust, etc. entering the installation groove 5, playing a protective role. Installation bolts are passed through the cover plate 18, and connection grooves 19 matching the dimensions of the installation bolts are opened on the surface of the material tray 2 facing the cover plate 18. The installation bolts are threadedly connected in the connection grooves 19. Operators can disassemble the cover plate 18 from the material tray 2 by using the method of bolt disassembly. It is more flexible and convenient for subsequent replacement of cover plates 18 of different model sizes.

[0045] The implementation principle of the embodiment of the present application is as follows: The screws and insulating particles are sequentially conveyed to the material tray 2 through feeding. The limiting groove 6 plays a role in limiting the position of the insulating particles, and the limiting hole 10 plays a role in limiting the position of the screws. The driving motor 20 is started to drive the second pulley 23 to rotate, and through the belt 24, the first pulley 22 at the input end of the speed reducer 21 is driven to rotate synchronously. Since the material tray 2 is arranged at the output end of the speed reducer 21, the rotation speed of the material tray 2 can be controlled, driving the material tray 2 at the output end of the speed reducer 21 to rotate, and the position of the limiting unit 3 on the material tray 2 can be changed. After the screws are sleeved, the limiting unit 3 with the sleeved screws is rotated to the discharge end of the material tray 2;

[0046] Start the telescopic cylinder 11 to drive the conical top rod 12 at the output end of the telescopic cylinder 11 to extend and insert into the top hole 15, thereby driving the first clamping block 7 and the second clamping block 8 to open. The first spring 16 is pressed tightly between the first clamping block 7 and the groove wall of the installation groove 5, and the second spring 17 is pressed tightly between the second clamping block 8 and the groove wall of the installation groove 5. The first clamping block 7 and the second clamping block 8 are in an open state, and the first clamping block 7 and the second clamping block 8 release the restriction on the sleeved screw. The sleeved screw falls into the material receiving pipe 25 under the action of gravity, realizing the automatic feeding and collection of the sleeved screw; when the conical top rod 12 retracts under the drive of the telescopic cylinder 11, the first clamping block 7 resets under the action of the first spring 16, and the second clamping block 8 resets under the action of the second spring 17. At this time, the first clamping block 7 and the second clamping block 8 reset to a closed state. The feeding unit 4 is used to release the limit on the limiting unit 3, thereby realizing the automatic feeding of the sleeved screw, reducing labor costs, saving time and effort, and improving the feeding speed and production efficiency of the screw sleeving.
