[0057] This embodiment provides a writing pen detection device, which is used to detect a workpiece to be detected, wherein the workpiece to be detected can be a writing pen, especially a gel pen. Figure 1 As shown, the writing pen detection device includes a wax head detection device 3 and an appearance detection device 4. The wax head detection device 3 is arranged outside the turntable 10. The wax head detection device 3 is used to detect the wax head of the workpiece to be detected, wherein the wax head can protect the pen tip.

[0058] The writing pen inspection device provided in this embodiment has a wax head inspection device 3 for inspecting the wax head of the workpiece to be inspected, and an appearance inspection device 4 for inspecting the exterior of the workpiece to be inspected, for example, the tip sleeve, sheath, label, pen head and pen barrel of the workpiece to be inspected. With the cooperation of the wax head inspection device 3 and the appearance inspection device 4, the wax head and appearance quality inspection of the workpiece to be inspected can be realized, the labor intensity of the operator can be reduced, time and effort can be saved, and the inspection production efficiency can be improved. At the same time, the interference of the operator's subjective factors and experience can be reduced, the inspection consistency is good, and the inspection accuracy is improved.

[0059] In one embodiment, Figure 1 As shown, the turntable 10 is provided with a carrier 11, and the carrier 11 is used to carry the workpiece to be detected arranged along the first direction. While carrying the workpiece to be detected, the carrier 11 also provides a storage space for the workpiece to be detected. The first direction is the axial direction of the turntable 10, and the first direction is specifically the vertical direction, that is, the workpiece to be detected is placed in the carrier 11 in a vertical state, the head end of the workpiece to be detected along the first direction is the pen tip end, and the tail end of the workpiece to be detected along the first direction is the pressing part.

[0060] In one embodiment, Figure 1As shown, the writing pen detection device also includes an in-place detection device 1, a pressing device 2, a resetting device 5, a first rejection device 6, a second rejection device 7 and a finished product conveying device 8. The in-place detection device 1 is used to detect whether there is a workpiece to be detected in the carrier 11 to avoid empty inspection. The pressing device 2 is used to press the tail end of the workpiece to be detected along the first direction to press out the wax head of the workpiece to be detected, so that the wax head detection device 3 can detect whether the wax head is intact. The resetting device 5 is used to press the tail end of the workpiece to be detected along the first direction again to retract and reset the wax head of the workpiece to be detected, and then the first rejection device 6 can reject the unqualified workpiece to be detected with a bad wax head after being inspected by the wax head detection device 3. The appearance detection device 4 is used to detect the appearance of the workpiece to be detected, and the second rejection device 7 can reject the unqualified workpiece to be detected with a bad appearance after being inspected by the appearance detection device 4. The finished product conveying device 8 can convey the finished workpieces that have been inspected to achieve the purpose of final classification.

[0061] Specifically, the in-place detection device 1 corresponds to the in-place detection station, the wax head detection device 3 corresponds to the wax head detection station, the pressing device 2 corresponds to the pen tip pressing station, the wax head detection device 3 is arranged above the turntable 10 along the first direction, the pressing device 2 is arranged below the turntable 10 along the first direction, the orthographic projection of the wax head detection device 3 on the turntable 10 and the orthographic projection of the pressing device 2 on the turntable 10 at least partially overlap, then the wax head detection station and the pen tip pressing station can be approximated as one station. The reset device 5 corresponds to the reset station, the first rejection device 6 corresponds to the bad wax head removal station, the appearance detection device 4 corresponds to the appearance detection station, the second rejection device 7 corresponds to the bad appearance removal station, and the finished product conveying device 8 corresponds to the finished product removal station.

[0062] In one embodiment, the in-place detection device 1 , the wax head detection device 3 , the resetting device 5 , the first rejection device 6 , the appearance detection device 4 and the second rejection device 7 are arranged along the circumference of the turntable 10 .

[0063] As the turntable 10 rotates, it is possible to switch freely between the in-place inspection station, the wax head inspection station, the reset station, the bad wax head removal station, the appearance inspection station, the bad appearance removal station and the finished product removal station. Each station is independent of each other and does not interfere with each other, and has good independence. At the same time, each station can be carried out at the same time, that is, during the rotation of the turntable 10, each inspection process can be realized at the same time, thereby improving the inspection production efficiency.

[0064] Among them, a gap is set between the turntable 10 corresponding to the in-place inspection station and the appearance defect removal station, which can be used as a loading station. The gripping device transports the workpiece to be inspected from the assembly machine to the loading station and places the workpiece to be inspected in the carrier 11.

[0065] It is understandable that there are multiple carriers 11, and multiple carriers 11 are arranged on the turntable 10 along the circumference of the turntable 10, so that each time the turntable 10 rotates an angle, the workstation switching can be achieved. Of course, each workstation can correspond to one carrier 11, or multiple carriers 11 at the same time, which can be adjusted according to actual production conditions.

[0066] In one embodiment, Figure 2 As shown, the appearance inspection device 4 of the writing pen inspection equipment further includes a main rotation driving source 12 and a transmission structure 13. The main rotation driving source 12 is connected to the turntable 10 through the transmission structure 13 to drive the turntable 10 to rotate.

[0067] Among them, the main rotation driving source 12 can be specifically selected as a driving motor, and the transmission structure 13 includes a reduction box 131, a transmission member 133 and a divider 132. The output end of the main rotation driving source 12 is connected to the input end of the reduction box 131, and the reduction box 131 plays the role of deceleration and torque increase. The output end of the reduction box 131 is connected to the divider 132 through the transmission member 133, and the transmission member 133 plays the role of intermediate power transmission. The divider 132 can also be called a divider. The divider 132 is connected to the turntable 10, and the rotation angle of the turntable 10 can be divided, that is, the turntable 10 rotates a certain angle at intervals, so that the turntable 10 realizes intermittent rotation motion, so as to ensure that there is sufficient operation time at each station, thereby ensuring the accuracy of detection.

[0068] In one embodiment, Figure 3 As shown, the carrier 11 includes a carrier 111, a sleeve 112, an ejector pin 113, a first connecting seat 114 and a second connecting seat 115. The carrier 111 is provided with a mounting groove for mounting a workpiece to be detected. The sleeve 112 is connected to the mounting groove. One end of the sleeve 112 is passed through the carrier 111, and the other end is connected to the first connecting seat 114. The second connecting seat 115 is provided on a side of the first connecting seat 114 away from the carrier 111. The ejector pin 113 is provided on the second connecting seat 115, and the ejector pin 113 is passed through the sleeve 112 and slidably cooperates with the sleeve 112.

[0069] When the ejector pin 113 slides along the sleeve 112 toward the carrier 111, the ejector pin 113 can pass through the bottom of the mounting groove and contact the tail end of the workpiece to be detected, so as to press the tail end of the workpiece to be detected, so that the wax head of the workpiece to be detected is exposed from the pen tip, and the tail end of the workpiece to be detected can be pressed again to retract the wax head of the workpiece to be detected into the pen tip. The ejector pin 113 can slide along the sleeve 112, and the sleeve 112 plays a guiding role for the ejector pin 113 to ensure the smooth movement of the ejector pin 113 along the first direction, thereby ensuring the reliability of the extension or retraction of the wax head.

[0070] In one embodiment, Figure 4-Figure 5As shown, the in-place detection device 1 is arranged on the outside of the turntable 10, and the in-place detection device 1 includes a connecting plate 101, a detection shaft 102, a detection ring 103, a detection block 104, a driving shaft 105 and a detection piece 106. The detection shaft 102 is penetrated by the connecting plate 101 and slidably cooperates with the connecting plate 101; the detection ring 103 is arranged at one end of the detection shaft 102 facing the turntable 10, and is used to press against the head end of the workpiece to be detected along the first direction; the detection block 104 is arranged at one end of the detection shaft 102 away from the turntable 10; the driving shaft 105 is connected to the connecting plate 101, and the driving shaft 105 can drive the connecting plate 101 to move along the first direction, and the detection piece 106 is used to detect the detection block 104.

[0071] The driving shaft 105 drives the detection shaft 102 and the detection member 106 to move downward in the first direction as a whole through the connecting plate 101. The detection ring 103 and the detection block 104 are fixed at both ends of the detection shaft 102. When the detection ring 103 contacts the workpiece to be detected downward, the detection shaft 102 slides relative to the connecting plate 101 and lifts the detection block 104 through the detection shaft 102. The detection member 106 is arranged on the connecting plate 101. If the detection member 106 detects the detection block 104, it means that there is a workpiece to be detected in the support seat 111 corresponding to the in-place detection station; if the detection member 106 does not detect the detection block 104, it means that there is no workpiece to be detected in the support seat 111 corresponding to the in-place detection station.

[0072] In one embodiment, Figure 4 and Figure 6 As shown, the writing pen detection device also includes a pressing device 2, which is arranged below the turntable 10 along the first direction. The pressing device 2 is arranged corresponding to the in-place detection device 1, and the pressing device 2 is used to press the tail end of the workpiece to be detected along the first direction.

[0073] Since the pressing device 2 is arranged corresponding to the in-place detection device 1, the in-place detection device 1 presses the head end of the workpiece to be detected along the first direction to ensure that the position of the head end of the workpiece to be detected remains fixed. The pressing device 2 is arranged below the turntable 10 along the first direction. The pressing device 2 presses the tail end of the workpiece to be detected along the first direction, so that the wax head of the workpiece to be detected extends relative to the pen tip, so that the wax head detection device 3 can perform wax head detection.

[0074] Specifically, Figure 6As shown, the push device 2 includes a push fixing plate 201 and a push driving source 202. The push fixing plate 201 is arranged below the turntable 10 along the first direction. The push driving source 202 is arranged on the push fixing plate 201. The output end of the push driving source 202 is connected with a push block. The push driving source 202 drives the push block to move upward along the first direction, so that the push block abuts against the push pin 113. The push pin 113 slides along the sleeve 112 and abuts against the tail end of the workpiece to be detected. The output end or the ejector block of the pressing drive source 202 is not directly connected to the ejector pin 113, that is, the ejector pin 113 of the carrier 11 and the pressing device 2 are split structures. Before or after the workpiece to be inspected is pressed, the pressing device 2 and the carrier 11 can release the contact connection relationship in time, which will not affect the rotation of the turntable 10, thereby avoiding the pressing device 2 from interfering with the rotation of the turntable 10.

[0075] In one embodiment, Figure 7-Figure 8 As shown, the wax head detection device 3 includes a first fixing component 31 and a wax head detection component 32. The first fixing component 31 is at least partially disposed on the turntable 10, and is used to clamp the workpiece to be detected along the circumference of the workpiece to be detected; the wax head detection component 32 is disposed on the outside of the turntable 10 and corresponds to the first fixing component 31, and is used to detect the wax head of the workpiece to be detected.

[0076] As the turntable 10 rotates, when the workpiece to be inspected arrives at the wax head inspection station, the first fixing component 31 is used to fix the workpiece to be inspected, and then the wax head of the workpiece to be inspected is inspected by the wax head inspection component 32. Under the cooperation of the first fixing component 31 and the wax head inspection component 32, the accuracy of the wax head inspection is improved.

[0077] In one embodiment, Figure 9-10 As shown, the first fixed component 31 includes two parts, namely a fixed part and a mold clamping part. The fixed part is arranged outside the turntable 10, and the mold clamping part is arranged on the turntable 10. Specifically, the fixed part includes a first fixed block 311 and a first fixed driving source 312. The first fixed block 311 is provided with a first groove on the side facing the turntable 10. The first fixed driving source 312 is arranged outside the turntable 10. The output end of the first fixed driving source 312 is connected to the first fixed block 311. The first fixed driving source 312 drives the first fixed block 311 to move in a direction close to the turntable 10. The mold clamping part includes a second fixed block 313 and a second fixed driving source 314. The second fixed block 313 is provided with a second groove on the side facing the first groove. The second fixed driving source 314 is arranged on the turntable 10, and the output end of the second fixed driving source 314 is connected to the second fixed block 313.

[0078] Under the action of the first fixed driving source 312 and the second fixed driving source 314, the first fixed block 311 and the second fixed block 313 move towards each other, so that the first groove and the second groove are respectively wrapped around the outside of the workpiece to be detected, and are used to clamp and fix the workpiece to be detected along the circumferential direction to ensure the position stability of the workpiece to be detected.

[0079] The first groove and the second groove can be arc grooves, and the inner wall of the first groove and the inner wall of the second groove are adapted to the outer wall of the workpiece to be detected, so that the first groove and the second groove have a conformal effect. The first groove and the second groove can be semicircular grooves, and the first groove and the second groove can be closed to form a circular hole for the workpiece to be detected to pass through, further improving the fixing effect of the workpiece to be detected.

[0080] In one embodiment, Fig.11 As shown, the wax head detection assembly 32 includes a wax head detection seat 321, a wax head detection adjustment slide 322, a wax head detection light source 323 and a wax head detection camera 324. The wax head detection seat 321 is fixed to the outside of the turntable 10, the wax head detection adjustment slide 322 is arranged on the wax head detection seat 321, the wax head detection light source 323 and the wax head detection camera 324 are arranged correspondingly, the wax head detection light source 323 can be a supplementary light source for the wax head detection camera 324, and the wax head detection camera 324 is used to detect the wax head of the workpiece to be detected. Among them, the wax head detection light source 323 can be an annular light source to increase the uniformity of the fill light range of the wax head detection camera 324. The wax head detection light source 323 and the wax head detection camera 324 are both arranged on the wax head detection adjustment slide 322, and the wax head detection adjustment slide 322 can adjust the position of the wax head detection camera 324 and the wax head detection camera 324. The position includes but is not limited to the height position along the first direction, the horizontal position along the second direction, and the first direction and the second direction are arranged perpendicular to each other.

[0081] It is understandable that the wax head detection seat 321 is provided with an avoidance hole, and the first fixing block 311 of the fixed part of the first fixing component 31 can pass through the avoidance hole to contact the workpiece to be detected, and the avoidance hole plays a role in avoiding the first fixing block 311. At the same time, in this way, the positions of the wax head detection component 32 and the first fixing component 31 are as close as possible, ensuring the synchronization of the fixation of the workpiece to be detected and the wax head detection.

[0082] In one embodiment, Figure 8 As shown, the writing pen detection equipment also includes a second fixing component 9 and a resetting device 5. The second fixing component 9 is arranged on the outside of the turntable 10 and between the appearance detection device 4 and the wax head detection device 3, and is used to clamp the workpiece to be detected along the circumference of the workpiece to be detected; the resetting device 5 is arranged below the turntable 10 along the first direction, and the resetting device 5 is arranged corresponding to the second fixing component 9. The resetting device 5 is used to press the tail end of the workpiece to be detected along the first direction.

[0083] As the turntable 10 rotates, after the wax head detection of the workpiece to be detected is completed, the second fixing component 9 is used to fix the workpiece to be detected, and then the reset device 5 presses the tail end of the workpiece to be detected to reset it. Under the cooperation of the first fixing component 31 and the reset device 5, the workpiece to be detected is guaranteed to be restored to the initial state.

[0084] It can be understood that the second fixing assembly 9 and the first fixing assembly 31 have similar structures, and the only difference is that they are arranged at different positions on the turntable 10. The first fixing assembly 31 and the wax head detection assembly 32 are arranged correspondingly, and the second fixing assembly 9 and the reset device 5 are arranged correspondingly, so the specific details of the structure are not repeated. Of course, the first fixing assembly 31 and the second fixing assembly 9 are arranged adjacent to each other, and the first fixing assembly 31 and the second fixing assembly 9 can share the same mounting seat and be arranged on the turntable 10.

[0085] It can be understood that the structures of the pressing device 2 and the resetting device 5 are similar, and the only difference is that they are set at different positions on the turntable 10. The pressing device 2 and the in-place detection device 1 are set correspondingly, and the resetting device 5 and the second fixed component 9 are set correspondingly, so the specific details of the structure are not repeated.

[0086] like Figure 12-Figure 17 As shown, this embodiment also provides an appearance detection device 4, which includes a clamping mechanism 41, a pressurizing mechanism 42, a rotating mechanism 43 and an appearance detection mechanism 44. The clamping mechanism 41 is arranged on the outside of the turntable 10, and is used to clamp the two ends of the workpiece to be detected along the first direction; the pressurizing mechanism 42 is connected to the clamping mechanism 41, and is used to drive the clamping mechanism 41 to move along the first direction; the rotating mechanism 43 is connected to the pressurizing mechanism 42, and the rotating mechanism 43 is connected to the pressurizing mechanism 42, and the rotating mechanism 43 drives the clamping mechanism 41 and drives the workpiece to be detected to rotate; the appearance detection mechanism 44 is arranged on the outside of the turntable 10, and is used to detect the outside of the workpiece to be detected.

[0087] The appearance inspection device 4 provided in this embodiment has a clamping mechanism 41 that clamps the two ends of the workpiece to be inspected along the first direction, that is, the clamping mechanism 41 clamps the head end and the tail end of the workpiece to be inspected, while ensuring the fixing effect of the workpiece to be inspected, it will not block the outer wall part of the main body of the workpiece to be inspected. The rotating mechanism 43 drives the clamping mechanism 41 and drives the workpiece to be inspected to rotate. As the workpiece to be inspected rotates, the appearance inspection mechanism 44 can inspect the circumference of the workpiece to be inspected to ensure that the entire circle of the workpiece to be inspected can be detected, and the inspection accuracy is high. At the same time, the pressure mechanism 42 drives the clamping mechanism 41 to move in the first direction toward the direction close to the turntable 10. The pressure mechanism 42 provides a pressure to the workpiece to be inspected through the clamping mechanism 41, further improving the fixing effect, and the pressure mechanism 42 drives the clamping mechanism 41 to move in the first direction away from the turntable 10, so that the clamping mechanism 41 can retreat to avoid the turntable 10 and reduce the risk of interfering with the rotation of the turntable 10.

[0088] In one embodiment, the clamping mechanism 41 includes a first clamping assembly 411, and the first clamping assembly 411 is used to clamp the head end of the workpiece to be inspected along the first direction. The first clamping assembly 411 can be used to fix the head end of the workpiece to be inspected.

[0089] Specifically, Figure 13-14 As shown, the first clamping assembly 411 includes a clamping plate 4111 and a clamping ring 4112. One side of the clamping plate 4111 along the first direction is connected to the pressure mechanism 42, and the other side of the clamping plate 4111 is connected to the clamping ring 4112. The clamping ring 4112 is sleeved on the head end of the component to be detected. The clamping ring 4112 can be made of elastic material. The clamping force of the clamping ring 4112 is kept moderate, which ensures that the head end of the component to be detected is secured while preventing damage to the head end of the workpiece to be detected.

[0090] The pressurizing mechanism 42 includes a first pressurizing component 421, which is located above the carrier 11 along the first direction, and is connected to the clamping plate 4111, and drives the clamping plate 4111 to move up and down along the first direction. Specifically, the first clamping component 411 can be a downward pressure cylinder, a moving motor, etc.

[0091] The rotating mechanism 43 includes a first rotating component 431, which is connected to the first clamping component 411 through the first pressurizing component 421 and is used to drive the first clamping component 411 to rotate. The first pressurizing component 421 drives the first clamping component 411 to move along the first direction. The first rotating component 431 is used to drive the first clamping component 411 to rotate.

[0092] Specifically, the first rotating assembly 431 includes a first rotating driving source 4311, a driving wheel 4312, a driven wheel 4313, and a transmission belt 4314. The first rotating driving source 4311 is arranged on a square seat. The first rotating driving source 4311 may be a first servo motor. The output end of the first rotating driving source 4311 is connected to the driving wheel 4312. The driven wheel 4313 and the first pressurizing assembly 421 are coaxially arranged. The transmission belt 4314 is wound around the driving wheel 4312 and the driven wheel 4313. When the first rotating driving source 4311 is working, the first rotating driving source 4311 drives the driving wheel 4312 to rotate. With the movement of the transmission belt 4314 and the rotation of the driven wheel 4313, the first pressurizing assembly 421 and the first clamping assembly 411 are driven to rotate. At this time, the head end of the component to be detected has three degrees of freedom: rotation, movement along the first direction, and circumferential clamping.

[0093] In one embodiment, the clamping mechanism 41 includes a second clamping assembly 412, and the second clamping assembly 412 is used to clamp the tail end of the workpiece to be inspected along the first direction. The second clamping assembly 412 can be used to fix the tail end of the workpiece to be inspected.

[0094] Specifically, Figure 15-16 As shown, the second clamping assembly 412 includes a clamping cylinder 4121 and a plurality of clamping jaws 4122. The output end of the clamping cylinder 4121 is connected to the plurality of clamping jaws 4122. The plurality of clamping jaws 4122 are arranged along the circumference of the workpiece to be inspected. The clamping cylinder 4121 drives the plurality of clamping jaws 4122 to move in a direction approaching each other, and the plurality of clamping jaws 4122 clamp the second connecting seat 115 of the carrier 11; the clamping cylinder 4121 drives the plurality of clamping jaws 4122 to move in a direction away from each other, and the plurality of clamping jaws 4122 release the second connecting seat 115 of the carrier 11.

[0095] In one embodiment, the rotating mechanism 43 includes a second rotating component 432, the second rotating component 432 includes a second rotating drive source, the second rotating drive source may be a rotating motor, and the output end of the second rotating drive source is connected to the clamping cylinder 4121 of the second clamping component 412 for driving the second clamping component 412 to rotate.

[0096] In one embodiment, the pressurizing mechanism 42 includes a second pressurizing assembly 422, which is connected to the second clamping assembly 412 via a second rotating assembly 432, and the second pressurizing assembly 422 is used to drive the second rotating assembly 432 to move along the first direction. While providing an upward pressurizing force to the second rotating assembly 432 and the second clamping assembly 412, the second pressurizing assembly 422 can also be separated from the turntable 10 and the workpiece to be inspected in a timely manner, without affecting the rotation of the turntable 10 and the transfer of the workpiece to be inspected to the next station.

[0097] Specifically, Fig.16As shown, the second pressurizing assembly 422 includes a cam 4221, a lifting block 4222 and a contact member 4223. The axial direction of the cam 4221 is perpendicular to the first direction. The lifting block 4222 is connected to the second rotating assembly 432. The contact member 4223 is disposed on the lifting block 4222. The contact member 4223 contacts the outer peripheral wall of the cam 4221, so that the lifting block 4222 drives the second rotating assembly 432 to move along the first direction.

[0098] Since the contact member 4223 and the outer peripheral wall of the cam 4221 are in contact with each other, the contact member 4223 may be a top block or a roller bearing, etc., and the roller bearing may support the cam 4221. As the cam 4221 rotates, the cam 4221 drives the contact member 4223 to move up and down along the first direction, and drives the second rotating assembly 432 and the second clamping assembly 412 to move along the first direction through the lifting block 4222. When the second clamping assembly 412 moves upward, the second clamping assembly 412 may clamp the second connecting seat 115 of the carrier 11, and when the second clamping assembly 412 moves downward, the second clamping assembly 412 may loosen the second connecting seat 115 of the carrier 11, so as to avoid the second clamping assembly 412 and the carrier 11 from being in rigid contact and interfering with the turntable 10.

[0099] In one embodiment, the main rotation driving source 12 is connected to the turntable 10 and the cam 4221 through a transmission structure 13 .

[0100] The transmission structure 13 is connected to the transmission shaft 4224, and the transmission shaft 4224 is inserted into the cam 4221. Since the rotation angle of the turntable 10 represents the switching between various stations, and the pause time of the turntable 10 represents the operation at the current appearance inspection station, a main rotation drive source 12 is used to simultaneously drive the rotation of the cam 4221 and the turntable 10, so that the rotation of the turntable 10 and the appearance inspection station operation are coordinated and adjusted with each other. At the same time, the power device is saved and the production cost is reduced.

[0101] In one embodiment, the second pressurizing assembly 422 further includes a guide rod 4225, one end of which is connected to the lifting block 4222, and the other end of which is slidably fitted relative to the turntable 10, so that the lifting block 4222 plays a guiding role when moving along the first direction.

The appearance detection camera 444 is set on the appearance detection slide 442, and the appearance detection slide 442 can adjust the position of the appearance detection camera 444. The position includes but is not limited to the height position along the first direction, the horizontal position along the second direction, and the first direction and the second direction are set perpendicular to each other.

[0105] In one embodiment, the second rejection device 7 is disposed outside the turntable 10 and between the appearance detection device 4 and the in-place detection device 1, and is used to reject the unqualified workpieces to be inspected after being inspected by the appearance detection device 4. The second rejection device 7 can be used to sort out the unqualified workpieces to be inspected to ensure the quality of the finished workpieces.

[0106] It can be understood that the structures of the first rejecting device 6 and the second rejecting device 7 are similar, and the only difference is the setting position and the type of clamped workpiece, so the specific details of the structure are not repeated.

[0107] It should be noted that the transmission structure 13 also includes a bevel gear set, the output end of the reduction box 131 is connected to the transmission shaft 4224, the transmission shaft 4224 is arranged in the bevel gear set, the number of the transmission shafts 4224 is four, and the four transmission shafts 4224 form a similar rectangular structure, and the three sets of bevel gear sets are located at three of the top angles of the rectangular structure.
