Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, of the embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

Please refer to fig. 1, which is a perspective view of a rotary conveyor according to an embodiment of the present invention. As shown in the figure, the rotary conveyor 1 includes a base frame 10, two limiting seats 11, a conveying assembly 12, and a driving assembly 13. The two limiting seats 11 are disposed on the base frame 10 at intervals and extend along the first direction DR 1. The conveyor assembly 12 includes a drive wheel 120, a driven wheel 121, and an endless conveyor belt 122. The driving wheel 120 and the driven wheel 121 are respectively disposed at two ends of the two limit seats 11. The annular conveyer belt 122 is disposed on the driving wheel 120 and the driven wheel 121, and a portion of the annular conveyer belt 122 is located between the two limiting seats 11. The endless conveyor belt 122 is configured to carry the carrier 2. The carrier 2 is located between the two retainers 11, and the two retainers 11 can limit the displacement of the carrier 2 in a second direction DR2, where the second direction DR2 is orthogonal to the first direction DR 1. The driving assembly 13 is connected to the driving wheel 120 to drive the endless belt 122 to circulate. In addition, the endless conveyor belt 122 may be divided into an upper layer portion and a lower layer portion. The upper section moves in a first direction DR1 and the product is assembled on the upper section. The lower portion moves in a direction opposite to first direction DR1 and the carrier reflows through the lower portion. In this way, the rotary conveyor 1 can achieve the effects of assembling the product and the reflow carrier with only one transmission line. Hereinafter, each component in the rotary conveyor 1 will be described in more detail.

In some embodiments, a positioning groove 110 is disposed on at least one of two opposite surfaces of the two spacing blocks 11. The positioning slot 110 extends along a first direction DR1, the positioning slot 110 cooperates with the positioning post of the carrier 2 to limit the displacement of the carrier 2 in a third direction DR3, the third direction DR3 is orthogonal to the first direction DR1 and the second direction DR 2. In other words, the positioning column of the carrier 2 can only move along the first direction DR1 in the positioning slot 110. That is, during the transportation, the position of the carrier 2 is fixed in the second direction DR2 in addition to the position in the third direction DR 3. Thus, high-precision positioning of the carrier 2 is achieved. In addition, detailed description of the carrier 2 will be mentioned in the following embodiments.

In some embodiments, the drive assembly 13 may include a base, a motor with a reducer, and a drive shaft. The base is disposed at one side of the driving wheel 120. The motor with reducer is arranged on the base and is connected with the driving wheel 120 through a transmission shaft. In this way, the motor with the speed reducer drives the endless belt 122 on the driving wheel 120 to circulate through the transmission shaft. However, the present application is not limited thereto, and the driving assembly 13 may include other kinds of motors. For example, in other embodiments, the motor may be a high torque motor using either ac or dc power.

Please refer to fig. 2, which is a schematic diagram of a tensioning mechanism according to an embodiment of the present invention. As shown, in some embodiments, the rotary conveyor 1 may further include a tensioning mechanism 14, the tensioning mechanism 14 being connected to the conveying assembly 12. The tensioning mechanism 14 includes a base 140, an adjusting seat 141, a connecting plate 142, a fixing seat 143, and a tensioning member 144. The adjusting seat 141 is slidably disposed on the base 140 along the first direction DR1, and the adjusting seat 141 is connected to the driven wheel 121. The connecting plate 142 is disposed on the adjusting seat 141. The fixing base 143 is fixedly disposed on the base 140. The two ends of the tensioning member 144 are respectively connected with the connecting plate 142 and the fixed seat 143. The tensioning member 144 adjusts the distance between the adjusting seat 141 and the fixing seat 143 to tension the endless conveyor belt 122. Specifically, the distance between the tensioning member 144 and the fixed seat 143 can be adjusted by the degree of screwing of the bolt relative to the nut.

For example, when the adjusting seat 141 is far away from the fixing seat 143, the adjusting seat 141 drives the driven wheel 121 to move along a direction opposite to the first direction DR 1. In other words, the driven wheel 121 approaches toward the driving wheel 120. As a result, the endless belt 122 on the driven wheel 121 and the driving wheel 120 is loosened. Alternatively, when the adjusting seat 141 approaches the fixing seat 143, the adjusting seat 141 drives the driven wheel 121 to move along the first direction DR 1. In other words, the driven wheel 121 moves away toward the driving wheel 120. As a result, the tension of the endless belt 122 on the driven wheel 121 and the driving wheel 120 occurs. Therefore, the rotary conveyor 1 can adjust the slack or tension of the endless conveyor belt 122 by the tension mechanism 14, so as to make the conveying process smoother. In addition, when a new adjusting endless conveyor belt 122 needs to be replaced, the old endless conveyor belt 122 may be loosened by the tensioning mechanism 14 and the new adjusting endless conveyor belt 122 may be replaced. Finally, the new endless conveyor belt 122 may be tensioned by the tensioning mechanism 14.

Referring back to fig. 1, in some embodiments, the rotary conveyor 1 may further include a stopper 15, and the stopper 15 is fixedly connected to the base frame 10, is located below the lower portion of the endless conveyor belt 122, and extends along the first direction DR 1. The stopper 15 is configured to limit displacement of the carrier 2 in the third direction DR 3. The number of the stoppers 15 may be one or two. Specifically, the stopper 15 is used to hold the carrier 2 at the lower layer of the endless belt 122, so as to prevent the carrier 2 from falling toward the ground during the reflow process. Alternatively, the carrier 2 is prevented from sagging toward the ground during the reflow process, so that the endless belt 122 is stretched to cause a reduction in positioning accuracy.

In some embodiments, a plurality of connectors 16 may be spaced apart from one another on the endless conveyor belt 122, and each connector may be detachably connected to a carrier 2. More specifically, the connecting element 16 may be a bump, which corresponds to a connecting slot under the carrier 2. In this way, the connecting member 16 can be engaged with the carrier 2, but the present invention is not limited thereto. For example, the connecting member 16 may be detachably connected to the carrier 2 by screws, tenons, magnetic attraction, and the like as recognized by those skilled in the art.

Please refer to fig. 3 and fig. 4, which are perspective views of an assembling apparatus and a station apparatus according to an embodiment of the present invention. As shown in the figure, the assembly apparatus includes a rotary conveyor 1 and a station apparatus 3. The rotary conveyor 1 in this embodiment may be similar to or the same as the rotary conveyor 1 in the above embodiments, and therefore, the description thereof is omitted. The station apparatus 3 includes a station support 30, a station base 31, and a station drive module 32. The station seat 31 is disposed on one side of the station support 30, the station seat 31 has at least one station 33, and the station 33 is disposed with a positioning assembly 34. The station driving module 32 is disposed on the station bracket 30, and the station driving module 32 is configured to drive the positioning assembly 34 in the second direction DR2, so that the positioning assembly 34 positions the carrier 2 located in the two retaining seats 11 in the first direction DR 1. In the present embodiment, the positioning assembly 34 approaches the carrier 2 on the rotary conveyor 1 along the second direction DR2 to fix the carrier 2 for processing. Alternatively, the positioning assembly 34 moves away from the carrier 2 on the rotary conveyor 1 in a direction opposite to the second direction DR2 to release the fixing and continue to convey the carrier 2. In other words, the station apparatus 3 of the present embodiment can be assembled with the rotary conveyor 1, so as to achieve the effect of automatic assembly. Hereinafter, each component in the station apparatus 3 will be described in more detail.

In some embodiments, the station drive module 32 may include a drive and a drive shaft. The driver is arranged on the work station bracket 30, and two ends of the driving shaft are respectively connected with the driver and the positioning assembly 34. For example, the driver may be a cylinder that drives the positioning assembly 34 to reciprocate linearly (i.e., in the second direction DR2) by converting the pressure of the compressed air into mechanical energy. Alternatively, the actuator may be an oil cylinder or an electric motor having the same or similar effect to achieve the same effect.

In some embodiments, positioning assembly 34 may include two positioning rods 340 extending along second direction DR2, and two positioning rods 340 may be inserted on opposite sides of carrier 2 to position carrier 2 in first direction DR 1. In other words, when the positioning assembly 34 is close to the carrier 2, the two positioning rods 340 on the positioning assembly 34 are received and positioned with the carrier 2, so that the carrier 2 does not move in the first direction DR 1. In this way, the carrier 2 can be accurately positioned.

In addition, in some embodiments, at least one of the two positioning rods 340 may have a chamfer 3400. That is, one of the two positioning rods 340 has a chamfer 3400, or both positioning rods 340 have chamfers 3400. Chamfer 3400 mates with a follower on one side of carrier 2. The angle of the chamfer 3400 may be 15 degrees, 30 degrees, 45 degrees, 60 degrees, or 75 degrees, but the present invention is not limited thereto. In other embodiments, the angle of chamfer 3400 may be between greater than 0 degrees and less than 90 degrees, and configured as practical.

Referring to fig. 4 and 5, fig. 5 is a schematic view of a positioning station according to an embodiment of the present invention. As shown, in some embodiments, at least one station 33 may include a positioning station 330, where the positioning station 330 includes a first stage 3300, a first guide rail 3301, a first stop 3302, a guide pin 3303, a first stop ring 3304, a first resilient member 3305, and a first driver 3306.

The first stage 3300 is disposed between the two positioning bars 340 at the station 33. First guide rail 3301 is disposed on first stage 3300, and first guide rail 3301 extends along second direction DR 2. The first limiting member 3302 is slidably disposed on the first guide rail 3301, and the first limiting member 3302 includes two first abutting convex portions 33020 disposed opposite to each other. The guide pin 3303 is movably inserted into the two first contact convex portions 33020 of the first stopper 3302. The first retainer 3304 is fitted over the guide needle 3303 and located between the two first abutment projections 33020. The first elastic member 3305 is sleeved on the guide needle 3303, and two ends of the first elastic member 3305 abut against between the first retainer ring 3304 and a first abutting convex portion 33020. The first driver 3306 is disposed on the first stage 3300, and the first driver 3306 is configured to drive the first stopper 3302 to move. For example, the first driver 3306 may be a cylinder that drives the first stopper 3302 to reciprocate linearly by converting the pressure of compressed air into mechanical energy. Alternatively, the first driver 3306 may be a hydraulic cylinder or an electric motor with the same or similar effect to achieve the same effect. To make the positioning station 330 more comprehensible, the operation of the positioning station 330 will be described in detail below.

Please refer to fig. 4, 5 and 6, wherein fig. 6 is a schematic diagram of a workpiece according to an embodiment of the present invention. The first driver 3306 drives the first limiting member 3302 to move along the first guide rail 3301 (i.e., along the second direction DR2), so that the first limiting member 3302 is close to the carrier 2 on the carousel conveyor 1. When the guide pins 3303 on the first stoppers 3302 enter the inside of the workpiece 4 on the carrier 2, the workpiece 4 is fixed by the guide pins 3303 to prevent play. In this way, the fixed workpiece 4 can be machined with high precision. For example, in the present embodiment, the workpiece 4 is a high-speed connector, which is provided with a connection hole 40. After one end 40B of the connection hole 40 is fixed by the guide pin 3303, the connection terminal is mounted in the other end 40A. However, the present invention is not limited thereto, and in other embodiments, the workpiece 4 may be other products having similar shapes.

On the other hand, when the first stop 3302 enters the connecting hole 40 of the workpiece 4 and abuts against a portion of the workpiece 4, the first driver 3306 still pushes the first stop 3302 to move. At this time, the guide pin 3303 which cannot advance moves backward (i.e., opposite to the second direction DR2) relative to the first stopper 3302, so that the first elastic member 3305 is compressed. As the first driver 3306 drives the first stopper 3302 to return, the first elastic member 3305 sleeved on the guide needle 3303 releases the compression force to restore the guide needle 3303. In addition, the first retainer 3304 is used to limit the first elastic member 3305 so that the guide needle 3303 does not exceed the initial position when it is reset.

In some cases, when the guide pin 3303 does not enter the connecting hole 40 of the workpiece 4 due to deviation (e.g., abuts against the periphery of the connecting hole 40), the guide pin 3303 may move backward by a greater distance with respect to the first stopper 3302. Accordingly, in some embodiments, the positioning station 330 may also include a sensor, such as an optical sensor. The sensor may be provided on first stage 3300 and located on the moving path of guide pin 3303 (it can also be interpreted that guide pin 3303 is located on the moving path of the sensor). When the first restraint member 3302 stops moving against the workpiece 4 (not located in the connecting hole 40), the sensor continues to move along the second direction DR2 with the first restraint member 3302. Since the guide pins 3303 are located on the sensor's moving path, the moving sensor is thus shielded by the stationary guide pins 3303. At this time, the operator or the control system can judge the positioning failure through the feedback of the sensor. It should be noted that the above description is only an example, and the present invention is not limited thereto. For example, in some embodiments, the operator or the control system determines the abnormality not by whether the sensor is shielded, but by whether the sensor is shielded early. For example, in the case of a normal positioning, the sensor may be interrupted after a certain time. However, in the event of a positioning failure, the sensor may be blocked earlier than a certain time. Therefore, it is possible to determine an abnormality by early interruption of the sensor.

Referring to fig. 4 and 7, fig. 7 is a schematic view of a detection station according to an embodiment of the present invention. As shown, in some embodiments, the at least one station 33 further includes a detection station 331, and the detection station 331 includes a second stage 3310, a second guide rail 3311, a second position limiter 3312, a probe 3313, a second stop 3314, a second elastic member 3315, a second driver 3316, and a first sensor 3317.

The second stage 3310 is disposed between two positioning rods 340 at the station 33. The second guide rail 3311 is disposed on the second stage 3310, and the second guide rail 3311 extends along a second direction DR 2. The second position-limiting member 3312 is slidably disposed on the second guide rail 3311, and the second position-limiting member 3312 includes two second abutting protrusions 33120 disposed oppositely. The probe 3313 is movably inserted through the two second abutting protrusions 33120 of the second position-limiting members 3312. The second stop ring 3314 is fixed on the probe 3313 and located between the two second stop protrusions 33120. The second elastic member 3315 is sleeved on the probe 3313, and two ends of the second elastic member 3315 abut against the second stopper 3314 and a second abutting protrusion 33120. The second driver 3316 is disposed on the second stage 3310, and the second driver 3316 is configured to drive the second position-limiting member 3312 to move. For example, the second driver 3316 may be a cylinder which drives the second stopper 3312 to linearly reciprocate by converting the pressure of compressed air into mechanical energy. Alternatively, the second driver 3316 may be a hydraulic cylinder or an electric motor or the like having the same or similar effect to achieve the same effect. The first sensor 3317 is disposed on the second stage 3310 and is located on the moving path of the probe 3313 (it can also be interpreted that the probe 3313 is located on the moving path of the first sensor 3317). The first sensor 3317 is configured as a sensing probe 3313. To make the inspection station 331 more comprehensible, the operation of the inspection station 331 will be described in detail below.

The second driver 3316 drives the second position-limiting member 3312 to move along the second guide rail 3311 (i.e., along the second direction DR2), so that the second position-limiting member 3312 is close to the carrier 2 on the rotary conveyor 1. When the probe 3313 of the second position-limiting member 3312 enters the workpiece 4 of the carrier 2, the probe 3313 contacts the assembled terminal. At this time, the first driver 3306 still pushes the first stopper 3302 to move. The probe 3313 is moved backward (i.e., opposite to the second direction DR2) relative to the second stopper 3312, so that the second elastic member 3315 is compressed. As the second driver 3316 drives the second position-limiting member 3312 to return, the second elastic member 3315 sleeved on the probe 3313 releases the compression force to reposition the probe 3313. In addition, the second stopper 3314 is used to limit the position of the second elastic member 3315, so that the probe 3313 does not exceed the initial position when resetting.

On the other hand, when the probe 3313 stops moving against the terminal in the connection hole 40, the first sensor 3317 moves along the second direction DR2 along with the second stopper 3312. Since the probe 3313 is located on the moving path of the first sensor 3317, the moving first sensor 3317 is shielded by the stationary probe 3313. At this time, the operator or the control system can judge the assembling result through the feedback of the sensor. For example, when the workpiece 4 is not successfully assembled with the terminals, the probes 3313 do not advance against the terminals. Thus, the first sensor 3317 may not be shielded by one end of the probe 3313, or may be shielded by one end of the probe 3313 later. Therefore, the operator or the control system can determine the abnormality of the assembly result by the feedback of the first sensor 3317.

Please refer back to fig. 4. In some embodiments, at least one of the stations 33 may also include a loading station 332 and a unloading station 333. The loading station 332, the positioning station 330, the detecting station 331 and the unloading station 333 are sequentially disposed along a first direction DR 1. The loading station 332 is used to place unassembled workpieces 4 on the carrier 2. The blanking station 333 is used to remove the assembled work pieces 4 from the carrier 2. When the upper portion of the endless conveyor 122 moves along the first direction DR1, the carriers 2 on the endless conveyor 122 are sequentially loaded, positioned, inspected, and unloaded. That is, through the four work stations 33, the present invention can realize the automatic assembly function.

Please refer to fig. 8 and 9, which are another perspective view of an assembly apparatus according to an embodiment of the present invention and an enlarged schematic view of an area a in fig. 8, respectively. As shown, in some embodiments, the assembly device may also include a second sensor 35. The second sensor 35 is disposed on one of the two retainers 11 away from the station device 3, and the second sensor 35 is configured to sense the workpiece 4 on the carrier 2 to determine whether the carrier 2 is in place. The second sensor 35 may be, for example, an infrared sensor.

Please refer to fig. 10 to 12, which are a perspective view, an exploded view, and a cross-sectional view of a line B-B' of fig. 10 of a carrier according to an embodiment of the present invention. As shown, the carrier 2 includes a base 20, a workpiece mount 21, and a follower 22. The base 20 has a recess 200. The workpiece mount 21 is slidably disposed in the groove 200 along the first direction DR 1. The follower 22 is disposed on one side of the workpiece mount 21 along the first direction DR 1.

In this embodiment, the follower 22 may cooperate with a positioning assembly 34 of the station apparatus 3. Specifically, when the station driving module 32 drives the two positioning rods 340 of the positioning assembly 34 to approach the carrier 2, one of the two positioning rods 340 contacts the follower 22. Upon contact, the follower 22 will adjust its position in the first direction DR1 along the chamfer 3400 on the positioning rod 340. That is, the follower 22 provided on the workpiece mount 21 brings the workpiece mount 21 into sliding movement in the groove 200 by contacting the chamfer 3400 on the positioning rod 340. In this way, the relative position between the workpiece attachment base 21 and the station 33 can be adjusted by the follower 22 and the positioning rod 340.

In some embodiments, the carrier 2 may further include a guide rail 23 and a slider 24, and the guide rail 23 and the slider 24 are disposed in the groove 200 along the first direction DR 1. Further, the work mounting base 21 includes a slide base 210 and a work fixing base 211. The sliding seat 210 is slidably disposed on the guide rail 23 by the slider 24. The workpiece fixing seat 211 is detachably provided on the sliding seat 210 and is used for fixing the workpiece 4. It should be noted that the pattern of the workpiece holder 211 shown in the drawings is merely an example. In practical use, the carrier 2 can correspond to different workpieces by replacing different workpiece fixing seats 211. Two different embodiments will be provided below to make the description of the workpiece holder 211 more comprehensible.

Please refer to fig. 13 and 14, which are schematic views of a workpiece holder and a workpiece according to an embodiment of the present invention. As shown, in some embodiments, the workpiece holder 211 may have a fixing through slot 2110A and a through hole 2111A facing the second direction DR2, and the through hole 2111A and the fixing through slot 2110A correspond to one end of the workpiece 4A. More specifically, the fixing penetration groove 2110A is fitted to the connection portion 41A of the workpiece 4A to fix the workpiece 4A. The through hole 2111A is fitted over the positioning end 42A of the workpiece 4A. During assembly, the positioning end 42A of the workpiece 4A is passed through by the guide pins 3303 or probes 3313, while the other end is fitted with a connection terminal.

In addition, please refer to fig. 15 and fig. 16, which are schematic views of a workpiece fixing base and a workpiece according to another embodiment of the present invention, respectively. As shown, in other embodiments, the workpiece holder 211 may have a fixing through slot 2110B and a through hole 2111B facing the second direction DR2, and the through hole 2111B and the fixing through slot 2110B correspond to one end of the workpiece 4B. More specifically, the fixing penetration groove 2110B is fitted to the connection portion 41B of the workpiece 4B to fix the workpiece 4B. The through hole 2111B is fitted over the positioning end 42B of the workpiece 4B. During assembly, the positioning end 42B of the workpiece 4B is passed through by the guide pin 3303 or the probe 3313, and the other end is mounted with a connection terminal. In this way, the carrier 2 can correspond to different workpieces by replacing different workpiece holders 211.

Please refer to fig. 10 to 12. In some embodiments, the follower 22 includes a roller 220 and a connecting rod 221, the connecting rod 221 is disposed on the sliding seat 210, and the roller 220 is disposed on an end of the connecting rod 221 away from the sliding seat 210. The roller 220 can be smoothly engaged with the positioning rod 340 of the assembly apparatus to reduce the friction force during the contact. However, the present invention is not limited thereto, and in other embodiments, the follower 22 may include a connecting rod having a chamfer. The connecting rod of the follower 22 can be matched with the chamfer 3400 of the positioning rod 340 through the chamfer, so that the effect of adjusting the position of the workpiece fixing seat 211 is realized.

As shown in fig. 12, in some embodiments, the base 20 further has a first sidewall 20A and a second sidewall 20B, the first sidewall 20A and the second sidewall 20B being opposite to each other in the first direction DR 1. In addition, the carrier 2 further includes a first limiting member 25 and an elastic member 26. The first limiting member 25 is disposed on the first sidewall 20A of the base 20 and extends into the groove 200. The elastic element 26 is sleeved on the first limiting element 25, and two ends of the elastic element 26 abut against the workpiece mounting seat 21 or between the sliding block 24 and the first sidewall 20A. In the present embodiment, both ends of the elastic member 26 abut between the slider 24 and the first side wall 20A. However, the present invention is not limited thereto, and in other embodiments, when the workpiece mounting seat 21 is directly disposed on the guide rail 23, both ends of the elastic member 26 abut between the workpiece mounting seat 21 and the first side wall 20A.

The elastic element 26 serves to increase the damping of the entire vehicle. Specifically, when the follower 22 comes into contact with the positioning rod 340 of the assembly apparatus, the workpiece mount 21 connected to the follower 22 may shake due to the contact. At this time, the elastic member 26 can absorb the shaking by compression. In addition, the workpiece mount 21 may be moved away from the positioning rod 340 in the first direction DR1 by the contact force. Thus, the elastic member 26 can also abut against the slider 24, so that the follower 22 connected to the slider 24 is continuously abutted against the positioning rod 340. In addition, the first limiting member 25 is used for guiding the elastic member 26.

In some embodiments, the carrier 2 may further include a second stopper 27, and the second stopper 27 is disposed on the second sidewall 20B of the base 20 and extends into the groove 200. The second stopper 27 is configured to restrain the workpiece mount 21. Specifically, the second stoppers 27 are configured to restrict the movement of the workpiece mount 21 on the slider 24 in the first direction DR 1.

As shown in fig. 10 and 11, in some embodiments, the base 140 further has a third sidewall 20C and a fourth sidewall (not shown), the third sidewall 20C and the fourth sidewall are opposite to each other in the second direction DR2, the second direction DR2 is orthogonal to the first direction DR1, and positioning posts 201 are disposed on the third sidewall 20C or/and the fourth sidewall. The positioning posts 201 correspond to the positioning slots 110 of the two limiting seats 11 of the rotary conveying device 1. More specifically, when the carrier 2 moves to the upper portion along with the endless conveyor belt 122, the positioning posts 201 of the carrier 2 enter the positioning grooves 110, so that the movement of the carrier 2 in the third direction DR3 is limited.

In some embodiments, the carrier 2 further includes a connecting slot disposed on the bottom surface of the base 140. The connecting groove corresponds to the connecting piece 16 of the rotary conveyor 1. More specifically, in the above-described embodiment, the connecting member 16 may be a projection. Thus, the connection slot under the carrier 2 corresponds to the connection piece 16. In this way, the carrier 2 and the connecting member 16 can be engaged with each other.

In some embodiments, the carrier 2 may further include a blocking block 28, and the blocking block 28 is disposed on the workpiece mount 21 and located on a side of the workpiece mount 21 close to the follower 22. The blocking block 28 is configured to block a third sensor 36 on the station device 3 to determine whether the carrier 2 is in place. When the third sensor 36 is blocked by a blocker on the vehicle 2, the third sensor 36 may send a signal to a control system of the assembly apparatus to stop the operation of the endless conveyor 122.

In some embodiments, the carrier 2 may further include a bar 29, the bar 29 being disposed on a side of the workpiece mount 21 away from the follower 22. One or both ends of the barrier strip 29 are provided with a chamfer 290. The chamfer 290 of the barrier 29 can cooperate with the chamfer 3400 of the positioning rod 340 to achieve the effect of adjusting the position of the workpiece holder 211.

In summary, the transmission assembly of the rotary conveyor is composed of the driving wheel, the driven wheel and the endless belt, and the driving assembly circularly conveys the carrier on a plane perpendicular to the ground, so as to achieve the effects of product assembly and carrier backflow. Therefore, the problem of low space utilization rate caused by the fact that the automation equipment needs to use two transmission lines can be solved. Furthermore, two limiting seats in the rotary conveying device limit the displacement of the carrier in the second direction, and the precision of the assembling process is effectively improved. In addition, the positioning station and the detection station in the assembly equipment can respectively process and detect the workpieces on the carrier. Furthermore, whether the assembly is abnormal or not can be confirmed through the guide needle and the probe on the positioning work station and the detection work station, so that the assembly quality is improved, and the requirement of manual judgment is reduced. Therefore, the rotary conveyer and the assembling equipment can effectively utilize the space and improve the precision and the efficiency of automatic assembling.
