Description

Technical Field

[0001] This application relates to the technical field of electronic device production, and particularly relates to a stopping and positioning mechanism and a production device. Background Art

[0002] With the rapid development of electronic devices, people's requirements for the production efficiency of electronic devices are also getting higher and higher. In the processing of electronic devices, the application of assembly line production equipment is becoming more and more extensive. In the assembly line production equipment, a stopping and positioning mechanism generally needs to be set so that the workpiece carrier stays at a specified position for testing or assembly. However, the existing stopping and positioning mechanism is likely to cause the position accuracy of the workpiece carrier to stay low, affecting subsequent testing or assembly. Utility Model Content

[0003] An embodiment of this application provides a stopping and positioning mechanism and a production device, which are used to solve the problem that the position accuracy of the workpiece carrier staying in the production device is low.

[0004] To achieve the above object, the embodiment of this application adopts the following technical solutions:

[0005] In a first aspect, a stopping and positioning mechanism is provided. The stopping and positioning mechanism includes a stopping component, a sliding member, a first elastic member, and a locking component. The stopping component includes a stopping block and a fixed seat. The stopping block can slide relative to the fixed seat along a first direction. A sliding groove is formed on the fixed seat, and the sliding groove extends along the first direction. The stopping block can move between a first position and a second position. One end of the sliding member extends into the sliding groove. The first elastic member is disposed on the sliding member and abuts between the sliding member and the fixed seat. The locking component is used to limit the movement direction of the sliding member. During the process of the stopping block sliding from the first position to the second position, the stopping block pushes the sliding member along the first direction and slides towards the direction close to the fixed seat, and the first elastic member is compressed. The locking component enables the sliding member to only slide towards the direction close to the fixed seat.

[0006] The workpiece carrier is transported by the conveyor belt of the device. When the workpiece carrier abuts against the stopping block, the workpiece carrier pushes the stopping block to slide from the first position to the second position. During this process, the stopping block pushes the sliding member to slide, and the sliding member slides to compress the first elastic member. The first elastic member can buffer and absorb the kinetic energy generated by the workpiece carrier.

[0007] Moreover, the locking component enables the sliding member to only slide towards the direction close to the fixed seat and cannot slide away from the fixed seat, so that the kinetic energy of the workpiece carrier absorbed by the first elastic member is locked. That is to say, during this process, the first elastic member will not rebound, and the workpiece carrier will not move repeatedly along the first direction due to the restoring force of the first elastic member. The workpiece carrier only has an impact force towards the direction close to the fixed seat. When the impact force of the workpiece carrier is zero, the workpiece carrier stops.

[0008] In this way, through the cooperation of the first elastic member, the sliding member and the locking assembly, while absorbing the impact force of the workpiece carrier, it is also possible to control the first elastic member so that it cannot rebound after being compressed, so that the speed of the workpiece carrier quickly returns to zero and does not move repeatedly in the first direction, thereby making it more convenient to control the stopping position of the workpiece carrier and improving the position accuracy of the workpiece carrier staying.

[0009] In a possible implementation manner of the first aspect, a plurality of grooves are formed in the sliding member, and the plurality of grooves are distributed in the first direction. The inner wall of the groove includes a first guiding surface and a first locking surface, the first guiding surface and the first locking surface are distributed in the first direction, and the first guiding surface is located on the side close to the stop block. The locking assembly includes a locking rod, and the end of the locking rod has a second locking surface.

[0010] During the process of the stop block moving from the first position to the second position, the end of the locking rod extends into the groove and is located between the first guiding surface and the first locking surface, and the second locking surface abuts against the first locking surface.

[0011] During the process of the stop block sliding from the first position to the second position, the end of the locking rod extends into the groove and is located between the first guiding surface and the first locking surface. The stop block pushes the sliding member to slide, and the second locking surface of the locking rod abuts against the first locking surface of the sliding member. The first locking surface is located on the side away from the stop block, so that the sliding member cannot slide in the direction close to the stop block. Through the cooperation of the first locking surface and the second locking surface, it is realized that the sliding member can only slide in the direction away from the stop block and cannot slide in the direction close to the stop block, so as to lock the kinetic energy of the workpiece carrier absorbed by the first elastic member.

[0012] In a possible implementation manner of the first aspect, the cross section of the sliding member can be polygonal, and the sliding groove matches the shape of the sliding member. That is to say, the cross-sectional profile of the sliding groove is also polygonal. The sliding member can slide along the first direction relative to the groove wall of the sliding groove. However, the sliding member will not rotate relative to the groove wall of the sliding groove, avoiding the misalignment of the end of the locking rod and the groove caused by the rotation of the sliding member, and improving the stability and reliability of the cooperation between the locking rod and the groove.

[0013] In a possible implementation manner of the first aspect, the end of the locking rod further has a second guiding surface, and the second guiding surface is parallel to the first guiding surface. The end of the locking rod extends into the groove, and the second guiding surface abuts against the first guiding surface.

[0014] In this structure, by setting the second guiding surface to cooperate with the first guiding surface, the contact area between the end of the locking rod and the second guiding surface is increased, so that the guiding effect of the second guiding surface is better, and the end of the locking rod can extend into the groove more smoothly in sequence, so that the sliding member can slide along the direction close to the fixed seat more smoothly.

[0015] In a possible implementation manner of the first aspect, along the direction from the bottom of the groove to the opening of the groove, the first guiding surface gradually moves away from the first locking surface. In this way, the end of the locking rod can extend into the groove more smoothly in sequence, so that the sliding member can slide along the direction close to the fixed seat more smoothly.

[0016] In a possible implementation manner of the first aspect, both the first locking surface and the second locking surface are perpendicular to the first direction. In this way, by setting the first locking surface and the second locking surface perpendicular to the movement direction of the sliding member, the first locking surface and the second locking surface can better limit the movement of the sliding member along the direction close to the stop block.

[0017] In a possible implementation manner of the first aspect, the stop block is slidably connected to the fixed seat. The stop positioning mechanism further includes a driving device, and the output end of the driving device is fixedly connected to the fixed seat. The driving device can drive the fixed seat and the stop block to move between a third position and a fourth position along a second direction, and the second direction intersects the first direction.

[0018] When the fixed seat and the stop block are in the third position, the stop block can abut against the workpiece carrier, and the locking assembly is connected to the sliding member. When the fixed seat and the stop block are in the fourth position, the stop block cannot abut against the workpiece carrier, and the locking assembly is separated from the sliding member.

[0019] In this structure, by setting the driving device to drive the fixed seat and the stop block to be able to move between the third position and the fourth position, it is realized that the stop block can freely switch whether to stop the workpiece carrier, and at the same time, it is realized that the locking assembly can freely switch whether to be connected to the sliding member, making the use of the stop positioning mechanism more flexible and convenient.

[0020] In a possible implementation manner of the first aspect, the second direction is perpendicular to the first direction. The direction in which the driving device drives the stop block to move is perpendicular to the movement direction of the workpiece carrier. Compared with the case where the included angle between the second direction and the first direction is an acute angle, there will be no mutual interference between the two movement directions, and the stop block can better stop the workpiece carrier, and the control is simpler.

[0021] In a possible implementation manner of the first aspect, the second direction is the vertical direction, which avoids interference or obstruction to the conveyor belt when the stop block moves between the third position and the fourth position, and reasonably utilizes the space between the conveyor belt and the machine frame, making the structure of the production equipment more compact.

[0022] Exemplarily, when the fixed seat and the stop block move to the fourth position, both the fixed seat and the stop block are located below the workpiece carrier. Therefore, the fixed seat and the stop block do not occupy other areas in the plane where the workpiece carrier is located. For example, when there are multiple parallel conveying paths and a workpiece carrier is arranged on each conveying path, the movement of the fixed seat and the stop block will not affect the movement of adjacent workpiece carriers, which is beneficial to improving the structural rationality of the production equipment.

[0023] In a possible implementation manner of the first aspect, a plurality of grooves are formed in the sliding member, and the plurality of grooves are distributed along the first direction. A receiving hole is formed in the fixed seat, and the receiving hole communicates with the sliding groove. The locking assembly includes a locking rod, and the locking rod extends into the receiving hole. When the fixed seat and the stop block are in the third position, the first end of the locking rod extends into the groove.

[0024] The hole wall of the receiving hole can guide the movement of the locking rod in the second direction, prevent the locking rod from shaking, and enable the locking rod to move stably in the second direction.

[0025] In a possible implementation manner of the first aspect, the locking assembly further includes a connecting rod and a second elastic member. The first end of the connecting rod is hinged to the second end of the locking rod, and the connecting rod is hinged to the fixed seat. A first boss is provided on the locking rod, and the second elastic member abuts between the fixed seat and the first boss.

[0026] During the process of the fixed seat and the stop block moving from the fourth position to the third position, the fixed seat compresses the second elastic member, and the second elastic member pushes the locking rod to move in a direction close to the sliding member.

[0027] In this structure, by setting the second elastic member to push the locking rod to move in a direction close to the sliding member, the movement direction of the sliding member can be restricted by the locking rod, and the structural design is ingenious.

[0028] In a possible implementation manner of the first aspect, a second boss is provided on the inner wall of one end of the receiving hole close to the sliding groove. When the fixed seat and the stop block are in the third position, the first boss abuts against the side of the second boss away from the sliding member.

[0029] In this way, the second boss can cooperate with the first boss to limit the movement distance of the locking rod in the second direction, avoid the locking rod moving excessively in the direction close to the sliding member and causing an obstacle to the movement of the sliding member, and make the movement stroke of the locking rod in the second direction more stable and reliable.

[0030] In a possible implementation of the first aspect, the stopping and positioning mechanism further includes a base, the driving device is arranged on the base, and an abutting protrusion is arranged on the base. The second end of the connecting rod can abut against the abutting protrusion, and the middle of the connecting rod is hinged to the fixed seat. During the movement of the fixed seat and the stopping block from the third position to the fourth position, the abutting protrusion pushes the connecting rod to rotate, and the connecting rod drives the locking rod to move away from the sliding member.

[0031] During the movement of the fixed seat and the stopping block from the third position to the fourth position, the second end of the connecting rod abuts against the abutting protrusion, causing the connecting rod to rotate, so that the first end of the connecting rod can drive the locking rod to move away from the sliding member, so that the end of the locking rod can disengage from the groove of the sliding member, and the second elastic member is gradually compressed.

[0032] During the movement of the fixed seat and the stopping block from the fourth position to the third position, the second end of the connecting rod is separated from the abutting protrusion, and the elastic force of the second elastic member pushes the locking rod to slide towards the sliding member, so that the end of the locking rod can be inserted into the groove of the sliding member, and the locking rod drives the connecting rod to rotate.

[0033] In a possible implementation of the first aspect, the locking assembly includes a shaft rod, one end of the shaft rod is fixedly connected to the fixed seat to realize the installation and fixation of the shaft rod, and the shaft rod can move with the fixed block. The other end of the shaft rod is hinged to the connecting rod, and the connecting rod can rotate around the shaft rod to drive the locking rod to move between the third position and the fourth position.

[0034] In a possible implementation of the first aspect, the fixed seat includes a fixed block and a support plate, and the fixed block is fixed on the support plate. The stopping block is slidably connected to the fixed block, and a receiving hole is opened on the fixed block. The output end of the driving device is connected to the support plate. The second elastic member abuts between the support plate and the first boss, so that the movement of the locking rod along the second direction can cause the second elastic member to deform, and the elastic force of the second elastic member drives the locking rod to reset.

[0035] In a possible implementation of the first aspect, the stopping and positioning mechanism further includes a reset member, and the reset member abuts between the stopping block and the fixed seat. During the movement of the stopping block from the first position to the second position, the reset member is compressed.

[0036] When the workpiece carrier moves to the specified position, the conveyor belt stops moving, and most of the kinetic energy of the workpiece carrier is absorbed and locked by the first elastic member. However, due to inertia, the workpiece carrier may still move a certain distance in the direction close to the fixed seat. The reset member pushes the stopping block to slide from the second position to the first position, and the stopping block can push the workpiece carrier back to the specified position. By setting the reset member, the position accuracy of the workpiece carrier can be higher.

[0037] In a possible implementation of the first aspect, the stop positioning mechanism further includes a guide rod, and a guide hole is formed on the fixing seat. One end of the guide rod is connected to the stop block, and the other end of the guide rod extends into the guide hole. The axis of the guide rod is parallel to the first direction, and the reset member is sleeved on the guide rod.

[0038] The guide rod can guide the deformation of the reset member along the first direction, reduce the shaking of the reset member, and make the deformation of the reset member along the first direction more stable and reliable.

[0039] In a possible implementation of the first aspect, the fixing seat includes a fixing block, the fixing block includes a first part and a second part, the first part is fixed to the second part, and the sliding groove is provided in the first part. The stop block includes an abutting portion and two sliding portions, and the two sliding portions are respectively fixed to two ends of the abutting portion. The stop block is arranged on the second part, the abutting portion and the first part are distributed along a first direction, and the two sliding portions are respectively located on both sides of the first part.

[0040] When the workpiece carrier pushes the abutment part to move along the first direction, the two sliding parts slide relative to the two sides of the first part, and the two sliding parts and the first part cooperate with each other for guiding and limiting, so that the stop block can stably slide relative to the fixed block along the first direction to prevent the stop block from shaking.

[0041] In a possible implementation manner of the first aspect, the fixed block further includes two third parts, the two third parts are arranged in a one-to-one correspondence with the two sliding parts, and the sliding part is located between the first part and the corresponding third part.

[0042] The first part, the second part and the third part together form a sliding track. The sliding part can slide relative to the corresponding sliding track. The sliding track can guide the sliding of the sliding part along the first direction, thereby improving the stability and reliability of the sliding of the sliding part along the first direction, and making the movement of the stop block along the first direction more reliable.

[0043] In a possible implementation of the first aspect, a guide groove and a guide protrusion are provided between the third part and the surface opposite to the sliding part, one of the guide groove and the guide protrusion is provided on the third part, and the other of the guide groove and the guide protrusion is provided on the sliding part. The guide groove extends along the first direction, and the guide protrusion extends into the guide groove.

[0044] Under this structure, the contact area between the sliding part and the third part is increased by cooperating with the guide protrusion and the guide groove, so that the sliding part can slide relative to the third part more stably, further improving the stability and reliability of the sliding part sliding along the first direction, thereby improving the stability and reliability of the sliding of the stop block.

[0045] In a possible implementation of the first aspect, the stopping block further includes a limiting portion, and the limiting portion is fixed to an end of the sliding portion away from the abutting portion; when the stopping block is in the first position, the limiting portion abuts against a side of the third part away from the abutting portion.

[0046] In this structure, by setting the limiting portion to limit the movement of the stopping block from the second position to the first position, it is avoided that the workpiece carrier is still pushed away from the fixing base after the stopping block reaches the first position, and the position accuracy of the workpiece carrier staying is improved.

[0047] In a possible implementation of the first aspect, the stopping and positioning assembly further includes a first buffer pad, and the first buffer pad is located on the surface of the stopping block away from the fixing base.

[0048] In this way, by setting the first buffer pad to buffer between the stopping block and the workpiece carrier, the impact force between the workpiece carrier and the stopping block is reduced, making the resilience of the workpiece carrier smaller. At the same time, the first buffer pad can also prevent the workpiece carrier or the stopping block from being damaged due to excessive impact force between the workpiece carrier and the stopping block, and prolong the service life of the workpiece carrier and the stopping block.

[0049] In a possible implementation of the first aspect, the stopping and positioning mechanism further includes an adsorption assembly, and the adsorption assembly is located on the surface of the stopping block away from the fixing base.

[0050] The adsorption assembly is used to adsorb the workpiece carrier so that the workpiece carrier moves together with the stopping block, making it more convenient for the stopping block to push the workpiece carrier back to the designated position.

[0051] In a possible implementation of the first aspect, the stopping and positioning mechanism further includes a second buffer pad, and the second buffer pad is arranged at the end of the sliding member away from the fixing base.

[0052] In this way, by setting the second buffer pad to buffer between the sliding member and the stopping block, the impact force between the sliding member and the stopping block is reduced, and it is avoided that the sliding member or the stopping block is damaged due to excessive impact force between the sliding member and the stopping block, and the service life of the sliding member and the stopping block is prolonged.

[0053] In the second aspect, a production device is further provided. The production device includes a frame, a conveyor belt, a driving mechanism, a working carrier, and a stopping and positioning mechanism. The conveyor belt is arranged on the frame. The driving mechanism is used to drive the conveyor belt to move. The working carrier is arranged on the conveyor belt. The stopping and positioning mechanism is arranged on the frame, and the working carrier can abut against the stopping block of the stopping and positioning mechanism.

[0054] Since the production device provided in this application includes the stopping and positioning mechanism of any of the above technical solutions in the first aspect, the two can solve the same technical problems and achieve the same effects. BRIEF DESCRIPTION OF THE DRAWINGS

[0081] In the embodiments of the present application, the terms "first", "second", and "third" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first", "second", and "third" may explicitly or implicitly include one or more of such features.

[0082] In the embodiments of the present application, the term "comprise", "include" or any other variation thereof is intended to cover non-exclusive inclusion, such that a process, method, article or device comprising a series of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article or device. Without further limitation, an element defined by the phrase "comprising a..." does not exclude the presence of additional identical elements in the process, method, article or device comprising such element.

[0083] Please refer to Figure 1 and Figure 2 , Figure 1 which is a schematic three-dimensional structure diagram of a production device provided by the embodiments of the present application, Figure 2 and which is a schematic top view of a production device provided by the embodiments of the present application. The embodiments of the present application provide a production device 200, and the production device 200 includes a frame 204, a conveyor belt 201, a workpiece carrier 202, a driving mechanism (not shown in the figure), and a stopping and positioning mechanism 100.

[0084] For the convenience of the following description, an XYZ coordinate system is established, and it is defined that the length direction of the conveyor belt 201 in the production device 200 is the X-axis direction, the width direction of the conveyor belt 201 is the Y-axis direction, and the thickness direction of the conveyor belt 201 is the Z-axis direction. It can be understood that Figure 1 only some components included in the production device 200 are schematically shown, and the actual shape, actual size, actual position and actual structure of these components are not limited by Figure 1 .

[0085] For the convenience of description, features representing spaces such as holes, slots, and holes in the drawings are marked with lead wires with arrows, and features representing solid structures are marked with lead wires without arrows.

[0086] The conveyor belt 201 is arranged on the frame 204, and the conveyor belt 201 extends along the X-axis direction. The driving mechanism is used to drive the conveyor belt 201 to rotate. Exemplarily, the conveyor belt 201 can be a belt, and the belt has advantages such as stable transmission, simple structure, easy maintenance, and low noise. The driving mechanism can include a driving motor and a pulley. The driving motor is used as a driving member, the output end of the driving motor is connected to the pulley, and the conveyor belt 201 is wound around the pulley. The driving motor rotates to drive the pulley to rotate, and the pulley drives the conveyor belt 201 to rotate.

[0087] Exemplarily, the number of the conveyor belts 201 can be two, and the two conveyor belts 201 are distributed along the Y-axis direction. By arranging two conveyor belts 201, the movement of the workpiece carrier 202 along the X-axis direction is more stable.

[0088] The workpiece carrier 202 is used to support the workpiece. The workpiece carrier 202 is placed on the conveyor belt 201. The rotation of the conveyor belt 201 can drive the workpiece carrier 202 and the workpiece to move in the X-axis direction.

[0089] The stop and positioning mechanism 100 is arranged on the frame 204. The stop and positioning mechanism 100 can be fixedly connected to the frame 204 to realize the installation and fixation of the stop and positioning mechanism 100. When the conveyor belt 201 drives the workpiece carrier 202 to move to the specified position, the stop and positioning mechanism 100 stops the workpiece carrier 202, so that the workpiece carrier 202 stops at the specified position to facilitate the testing or assembly of the workpiece.

[0090] In some embodiments, please continue to refer to Figure 1 and Figure 2 , the production equipment 200 may further include a lifting structure 203. The lifting structure 203 has a lifting rod 231. A positioning hole 206 is formed on the workpiece carrier 202. The shape of the lifting rod 231 matches that of the positioning hole 206, and the lifting rod 231 can be inserted into the positioning hole 206. When the stop and positioning mechanism 100 stops the workpiece carrier 202 at the specified position, the lifting rod 231 will be inserted into the positioning hole 206 to realize the connection between the lifting structure 203 and the workpiece carrier 202. Then the lifting structure 203 will drive the workpiece carrier 202 to rise or fall to facilitate operations such as testing or assembling the workpiece.

[0091] Please refer to Figure 1 and Figure 3 , Figure 3 is a schematic structural diagram of a stop and positioning mechanism provided by an embodiment of the present application. Some stop and positioning mechanisms include a driving member 301 and a stop structure 302. The driving member 301 is used to drive the stop structure 302 to rise or fall. When the workpiece carrier 202 moves to the specified position, the driving member 301 drives the stop structure 302 to rise, and the stop structure 302 stops the workpiece carrier 202, so that the workpiece carrier 202 stops at the specified position.

[0092] Please refer to Figure 1 , Figure 3 and Figure 4 , Figure 4 is for using Figure 3 in the stop and positioning mechanism of the workpiece carrier speed-time relationship schematic diagram. As Figure 3As shown, the stop structure 302 and the workpiece carrier 202 are in hard limit stop, that is to say, there is no buffer between the stop structure 302 and the workpiece carrier 202. When the moving speed of the workpiece carrier 202 is relatively high, for example, exceeding 100 mm / s, when the conveyor belt 201 stops rotating, the inertial force of the workpiece carrier 202 is relatively large, resulting in a large impact between the workpiece carrier 202 and the stop structure 302. Since the stop structure 302 is fixed, the workpiece carrier 202 will rebound a certain distance, resulting in a low position accuracy of the workpiece carrier 202 when it stops. After the workpiece carrier 202 stops moving, the lifting rod 231 and the positioning hole 206 cannot be coaxially positioned. During the process of inserting the lifting rod 231 into the positioning hole 206, wear will occur between the lifting rod 231 and the positioning hole 206. Even when the lifting rod 231 and the positioning hole 206 are misaligned, the lifting rod 231 will lift the workpiece carrier 202, resulting in the overturning of the workpiece carrier 202.

[0093] And, based on Figure 4 it can be known that since the workpiece carrier 202 and the stop structure 302 are in hard limit stop, the impact force between the workpiece carrier 202 and the stop structure 302 is relatively large, resulting in a long time for the workpiece carrier 202 to move back and forth along the X-axis direction.

[0094] Please refer to Figure 1 、 Figure 3 and Figure 5 , Figure 5 which is a schematic structural diagram of a buffer structure 303 provided by an embodiment of the present application. On this basis, some stop and positioning mechanisms further include a buffer structure 303. The buffer structure 303 can be connected to the stop structure 302. The buffer structure 303 can include a buffer member 331 and a spring 332. The buffer member 331 can be a hydraulic or pneumatic structure for providing movement resistance. Through the cooperation of the buffer member 331 and the spring 332, buffering is carried out to reduce the impact force between the workpiece carrier 202 and the stop structure 302.

[0095] Please refer to 5 and Figure 6 , Figure 6 which is Figure 5 a schematic diagram of the relationship between the speed and time of the workpiece carrier with the buffer structure 303 in Figure 1 . However, in the buffer structure 303, buffering is carried out through the spring 332. The spring 332 will be repeatedly compressed and rebounded, and the spring 332 will also push the workpiece carrier 202 (see Figure 1 ) to move back and forth along the X-axis direction, and the time for the workpiece carrier 202 to move back and forth is relatively long. Moreover, the process of the spring 332 pushing the workpiece carrier 202 to move back and forth is not easy to control, resulting in a still low position accuracy of the workpiece carrier 202 when it stops.

[0096] To solve the above problems, an embodiment of the present application provides a stop and positioning mechanism 100. Please refer to Figure 7And Figure 8 , Figure 7 is a schematic three-dimensional structure diagram of a stop and positioning mechanism 100 provided by an embodiment of the present application, Figure 8 and Figure 7 is an exploded structure diagram of the stop and positioning mechanism 100 in

[0097] The stop component 10 includes a stop block 11 and a fixed seat 12. The stop block 11 can slide relative to the fixed seat 12 along a first direction. The first direction is the X-axis direction. It can be understood that the first direction is consistent with the moving direction of the conveyor belt. The stop block 11 can abut against the workpiece carrier 202 (see Figure 1 ).

[0098] A sliding groove 121 is formed in the fixed seat 12, and the sliding groove 121 extends along the X-axis direction. The sliding member 20 extends along the X-axis direction, and one end of the sliding member 20 extends into the sliding groove 121. The sliding member 20 has an approximate rod-shaped structure, and the shape of the sliding groove 121 matches the shape of the sliding member 20. The sliding groove 121 can guide the sliding of the sliding member 20 along the X-axis direction, so that the sliding member 20 can slide stably and reliably along the X-axis direction.

[0099] A plurality of grooves 22 are formed in the sliding member 20, and the plurality of grooves 22 are distributed along the X-axis direction. The grooves 22 are located at one end away from the mounting protrusion 21. The inner wall of the groove 22 includes a first guiding surface 221 and a first locking surface 222. The first guiding surface 221 and the first locking surface 222 are distributed along the X-axis direction, and the first guiding surface 221 is located on the side close to the mounting protrusion 21.

[0100] In some embodiments, please continue to refer to Figure 7 and Figure 8 , the cross-section of the sliding member 20 can be polygonal, and the shape of the sliding groove 121 matches the shape of the sliding member 20. That is to say, the cross-sectional contour of the sliding groove 121 is also polygonal. The sliding member 20 can slide relative to the groove wall of the sliding groove 121 along the X-axis direction. However, the sliding member 20 will not rotate relative to the groove wall of the sliding groove 121, avoiding the misalignment of the end of the locking rod 41 and the groove 22 caused by the rotation of the sliding member 20, and improving the stability and reliability of the cooperation between the locking rod 41 and the groove 22.

[0101] Exemplarily, the cross-section of the sliding member 20 can be triangular, quadrilateral, pentagonal or other polygons, rather than a complete circle.

[0102] The first elastic member 30 extends along the X-axis direction, and the first elastic member 30 is disposed on the sliding member 20. Moreover, one end of the first elastic member 30 abuts against the sliding member 20, and the other end of the first elastic member 30 abuts against the fixed seat 12.

[0103] Exemplarily, the first elastic member 30 may be a spring, which has the advantages of convenient installation and easy replacement. The first elastic member 30 may be sleeved on the sliding member 20, and the sliding member 20 may play a guiding role in the deformation of the first elastic member 30 in the X-axis direction. The end of the sliding member 20 may have a mounting protrusion 21. One end of the first elastic member 30 may abut against the mounting protrusion 21, and the other end of the first elastic member 30 may abut against the fixed seat 12, so that the elastic force generated by the deformation of the first elastic member 30 can drive the sliding member 20 to slide.

[0104] In other embodiments, the first elastic member 30 may also be an elastic sleeve or other devices capable of generating elastic force. The embodiments of the present application do not limit the specific structure of the first elastic member 30, as long as it can generate elastic force in the X-axis direction.

[0105] Please refer to Figure 8 and Figure 9 , Figure 9 which is an exploded structural schematic diagram of the sliding member 20 and the locking rod 41 in a stop and positioning mechanism provided by an embodiment of the present application. The locking assembly 40 is used to limit the movement direction of the sliding member 20. The locking assembly 40 includes a locking rod 41, and the end of the locking rod 41 has a second locking surface 412.

[0106] During the process of the stop block 11 sliding from the first position to the second position, the end of the locking rod 41 extends into the groove 22 and is located between the first guiding surface 221 and the first locking surface 222. The stop block 11 pushes the sliding member 20 to slide, and the second locking surface 412 of the locking rod 41 abuts against the first locking surface 222 of the sliding member 20. The first locking surface 222 is located on the side away from the stop block 11, so that the sliding member 20 cannot slide in the direction close to the stop block 11. Through the cooperation of the first locking surface 222 and the second locking surface 412, it is realized that the sliding member 20 can only slide in the direction away from the stop block 11 and cannot slide in the direction close to the stop block 11, so as to lock the kinetic energy of the workpiece carrier 202 absorbed by the first elastic member 30.

[0107] On this basis, please continue to refer to Figure 8 and Figure 9 , the first locking surface 222 and the second locking surface 412 are both perpendicular to the first direction. The movement direction of the sliding member 20 is the first direction, that is, the X-axis direction. The first locking surface 222 and the second locking surface 412 are both perpendicular to the X-axis direction, and the first locking surface 222 and the second locking surface 412 may both extend along the Z-axis direction. By setting the first locking surface 222 and the second locking surface 412 to be perpendicular to the movement direction of the sliding member 20, the first locking surface 222 and the second locking surface 412 can better limit the movement of the sliding member 20 in the direction close to the stop block 11.

[0108] The end of the locking rod 41 can be in an approximately thin rod-shaped structure. The side of the end of the locking rod 41 away from the mounting protrusion 21 is the second locking surface 412. The side of the end of the locking rod 41 close to the mounting protrusion 21 can be in abutting contact with the first guiding surface 221 and slide along the first guiding surface 221 to enter the next groove 22, so that the sliding member 20 can slide in the direction away from the stopping block 11.

[0109] Based on this, please refer to Figure 8 and Figure 10 , Figure 10 which is an exploded structural schematic diagram of the sliding member 20 and the locking rod 41 in another stopping and positioning mechanism provided by the embodiment of the present application. The end of the locking rod 41 further has a second guiding surface 411. The second guiding surface 411 is parallel to the first guiding surface 221. The end of the locking rod 41 extends into the groove, and the second guiding surface 411 is in abutting contact with the first guiding surface 221.

[0110] Exemplarily, two adjacent grooves 22 are respectively a first groove 22a and a second groove 22b. The first groove 22a is located on the side close to the fixed seat. During the process of the stopping block 11 sliding from the first position to the second position, the end of the locking rod 41 first extends into the first groove 22a. The stopping block 11 pushes the sliding member 20 to slide in the direction close to the fixed seat 12. The first guiding surface 221 is in abutting contact with the second guiding surface 411, and the first guiding surface 221 slides relative to the second guiding surface 411, so that the end of the locking rod 41 disengages from the first groove 22a and extends into the second groove 22b. By setting the second guiding surface 411 to cooperate with the first guiding surface 221, the contact area between the end of the locking rod 41 and the second guiding surface 411 is increased, so that the guiding effect of the second guiding surface 411 is better, and the end of the locking rod 41 can extend into the groove 22 more smoothly in sequence, so that the sliding member 20 can slide more smoothly in the direction close to the fixed seat 12.

[0111] Please continue to refer to Figure 8 and Figure 10 , along the direction from the bottom of the groove 22 to the opening of the groove 22, the first guiding surface 221 gradually moves away from the first locking surface 222. That is to say, along the -Z direction, the first guiding surface 221 is inclined in the direction close to the mounting protrusion 21.

[0112] By setting the first guiding surface 221 to gradually move away from the first locking surface 222, the end of the locking rod 41 can disengage from the first groove 22a more smoothly to enter the second groove 22b, so that the end of the locking rod 41 can extend into the groove 22 more smoothly in sequence, so that the sliding member 20 can slide more smoothly in the direction close to the fixed seat 12.

[0113] Exemplarily, the included angle between the first guiding surface 221 and the first locking surface 222 may be 20°, 30°, 40°, 45°, 50°, 60°, 70°, 75° or 80°.

[0114] Please refer to Figure 11 and Figure 12 , Figure 11 which is a schematic cross-sectional view of the stop block 11 in the stop and positioning mechanism 100 provided by an embodiment of the present application when the stop block 11 is in the first position. Figure 12 which is a schematic cross-sectional view of the stop block 11 in the stop and positioning mechanism 100 provided by an embodiment of the present application when the stop block 11 is in the second position.

[0115] The stop block 11 can move between the first position and the second position. When the stop block 11 is in the first position, the workpiece carrier 202 is not in contact with the stop block 11. When the workpiece carrier 202 moves to the specified position, the conveyor belt 201 (see Figure 1 ) stops moving. Due to inertia, the workpiece carrier 202 still moves in the direction close to the fixed seat 12, so that the workpiece carrier 202 contacts the stop block 11, and the workpiece carrier 202 will push the stop block 11 to slide from the first position to the second position.

[0116] During the process of the stop block 11 sliding from the first position to the second position, the stop block 11 pushes the sliding member 20 in the X-axis direction and slides in the direction close to the fixed seat 12, and the first elastic member 30 is compressed. The end of the locking rod 41 is inserted into the groove 22 of the sliding member 20, so that the sliding member 20 can only slide in the direction close to the fixed seat 12.

[0117] That is to say, during the process of the workpiece carrier 202 pushing the stop block 11 to slide from the first position to the second position, the stop block 11 pushes the sliding member 20 to slide. The sliding of the sliding member 20 causes the first elastic member 30 to be compressed. The first elastic member 30 can buffer and absorb the kinetic energy generated by the workpiece carrier 202. The locking rod 41 of the locking assembly 40 makes the sliding member 20 can only slide in the direction close to the fixed seat 12 and cannot slide in the direction away from the fixed seat 12, so that the kinetic energy of the workpiece carrier 202 absorbed by the first elastic member 30 is locked.

[0118] Moreover, the first elastic member 30 does not rebound, and the first elastic member 30 does not push the workpiece carrier 202 to move repeatedly in the X-axis direction. The workpiece carrier 202 only has an impact force in the direction close to the fixed seat 12. When the impact force of the workpiece carrier 202 is zero, the workpiece carrier 202 stops. Through the cooperation of the first elastic member 30, the sliding member 20 and the locking rod 41, the impact force of the workpiece carrier 202 is absorbed, so that the speed of the workpiece carrier 202 drops rapidly, and the position where the workpiece carrier 202 stops can be controlled more conveniently, improving the position accuracy of the workpiece carrier 202 staying.

[0119] Please refer to Figure 13 , Figure 13 which is a schematic diagram showing the relationship between the speed and time of the workpiece carrier 202 of the stop and positioning mechanism 100 adopted in Figure 12 . It can be seen that Figure 13 the stop time of the workpiece carrier 202 in Figure 4 and Figure 6 is much less than 1 s, while the stop time of the workpiece carrier 202 shown in

[0120] is close to 1 s. When the initial speed of the workpiece carrier 202 is 100 mm / s, since the first elastic member 30 absorbs the function generated by the workpiece carrier 202 and cooperates with the locking assembly 40 and the sliding member 20, the kinetic energy of the workpiece carrier 202 absorbed by the first elastic member 30 is locked, the first elastic member 30 does not rebound, and the first elastic member 30 does not push the workpiece carrier 202 to move repeatedly along the X-axis direction. The time for the workpiece carrier 202 to decelerate from the start to a speed of zero is shorter than that of the prior art, thereby improving the work efficiency. Figure 14 Figure 14 On this basis, please refer to

[0121] which is a schematic cross-sectional view of the fixed seat 12 of a stop and positioning mechanism 100 provided in an embodiment of the present application in the third position. The stop and positioning mechanism 100 further includes a driving device 50, and the output end of the driving device 50 is fixedly connected to the fixed seat 12. Exemplarily, the driving device 50 may be a cylinder, and the cylinder has advantages such as stable output and high transmission accuracy. The driving device 50 may also be a motor or other devices capable of providing power, and the specific structure of the driving device 50 is not limited in the embodiment of the present application. Figure 1 The driving device 50 can drive the fixed seat 12 and the stop block 11 to move between the third position and the fourth position along the second direction, and the second direction intersects the first direction. For example, the second direction may be perpendicular to the first direction, that is to say, the direction in which the driving device 50 drives the stop block 11 to move is perpendicular to the movement direction of the workpiece carrier 202 (see

[0122] In some examples, the first direction may be the X-axis direction, the second direction may be the Y-axis direction, and the stop and positioning mechanism 100 is located on the conveyor belt 201 (see Figure 1 ​)One side in the Y-axis direction. Alternatively, the second direction can also be the Z-axis direction, and the stop and positioning mechanism 100 is located on one side of the conveyor belt 201 in the Z-axis direction, that is, the stop and positioning mechanism 100 can move below the conveyor belt 201. In the following embodiments, the second direction is taken as the Z-axis direction as an example for illustration.

[0123] As Figure 14 shown, when the workpiece carrier 202 is about to move to the specified position, the driving device 50 drives the fixed seat 12 and the stop block 11 to move upward to the third position so that the stop block 11 can contact the workpiece carrier 202. When the fixed seat 12 and the stop block 11 are in the third position, the first end 413 of the locking rod 41 extends into the groove 22 so that the locking rod 41 can limit the movement direction of the sliding member 20, making the sliding member 20 only able to slide towards the fixed seat 12 and not able to slide away from the fixed seat 12 (as Figure 11 shown). Then the workpiece carrier 202 contacts the stop block 11, and the workpiece carrier 202 pushes the stop block 11 from the first position to the second position (as Figure 12 shown). During the process of the stop block 11 moving from the first position to the second position, the first end 413 of the locking rod 41 extends into the groove 22 in sequence, and the locking rod 41 makes the sliding member 20 only able to slide towards the fixed seat 12.

[0124] Please refer to Figure 15 and Figure 16 . Figure 15 is a schematic cross-sectional view of the fixed seat 12 in a stop and positioning mechanism 100 provided by an embodiment of the present application at a certain angle in the fourth position, Figure 16 is a schematic cross-sectional view of the fixed seat 12 in a stop and positioning mechanism 100 provided by an embodiment of the present application at another angle in the fourth position. As Figure 15 shown, after the operator completes the test or assembly of the workpiece, the driving device 50 drives the fixed seat 12 and the stop block 11 to move from the third position to the fourth position, so that the stop block 11 is disengaged from the workpiece carrier 202, and the conveyor belt 201 (see Figure 1 ) rotates again, and the conveyor belt 201 drives the workpiece carrier 202 to move to the next specified position for testing or assembly. As Figure 16 shown, when the fixed seat 12 and the stop block 11 are in the fourth position, the first end 413 of the locking rod 41 disengages from the groove 22, so that the locking rod 41 cannot limit the movement direction of the sliding member 20, and the sliding member 20 can slide away from the fixed seat 12, and the kinetic energy of the workpiece carrier 202 absorbed by the first elastic member 30 can be released.

[0125] By setting the driving device 50 to drive the fixed seat 12 and the stop block 11 to move between the third position and the fourth position, it is possible to realize that the stop block 11 can freely switch whether to stop the workpiece carrier 202, making the use of the stop positioning mechanism 100 more flexible and convenient.

[0126] On this basis, please refer to Figure 17 , Figure 17 which is a schematic structural diagram of another stop positioning mechanism 100 provided by an embodiment of the present application. Figure 17 In [the figure], the fixed seat 12 and the stop block 11 are in the fourth position, and the first end 412 of the locking rod 41 is located outside the groove 22. A receiving hole 122 is formed in the fixed seat 12, and the receiving hole 122 extends along the Z-axis direction and is communicated with the sliding groove 121. The locking rod 41 extends into the receiving hole 122, and the hole wall of the receiving hole 122 can guide the movement of the locking rod 41 along the Z-axis direction, preventing the locking rod 41 from shaking in the X-axis and Y-axis directions, so that the locking rod 41 can stably move along the Z-axis direction.

[0127] In some embodiments, please refer to Figure 17 , the locking assembly 40 further includes a connecting rod 42 and a second elastic member 43. The connecting rod 42 extends along the Y-axis direction. The first end 421 of the connecting rod 42 is hinged to the second end 414 of the locking rod 41, and the connecting rod 42 is hinged to the fixed seat 12. The connecting rod 42 rotates relative to the fixed seat 12, and the first end 421 of the connecting rod 42 can drive the locking rod 41 to move along the Z-axis direction, so that the first end 413 of the locking rod 41 can be inserted into or separated from the groove 22.

[0128] A first boss 415 is provided on the locking rod 41, and the first boss 415 is located on the side close to the first end 413. The second elastic member 43 abuts between the fixed seat 12 and the first boss 415.

[0129] During the movement of the fixed seat 12 and the stop block 11 from the fourth position to the third position, the fixed seat 12 compresses the second elastic member 43, and the second elastic member 43 pushes the locking rod 41 in the direction close to the sliding member 20, and the first end 413 of the locking rod 41 can extend into the groove 22.

[0130] By setting the second elastic member 43 to push the locking rod 41 in the direction close to the sliding member 20, it is possible to realize that the locking rod 41 can limit the movement direction of the sliding member 20, and the structural design is ingenious.

[0131] Exemplarily, the second elastic member 43 can be a spring, and the spring has the advantages of convenient installation and easy replacement. The second elastic member 43 can be sleeved on the locking rod 41, and the locking rod 41 can guide the deformation of the second elastic member 43 along the Z-axis direction.

[0132] Based on this, please continue to refer to Figure 17 One end inner wall of the accommodation hole 122 close to the sliding groove 121 is provided with a second boss 123. When the fixed seat 12 and the stop block 11 are in the third position, the first boss 415 abuts against the side of the second boss 123 away from the sliding member 20. The second boss 123 can cooperate with the first boss 415 to limit the movement distance of the locking rod 41 along the Z-axis direction, avoid the locking rod 41 moving excessively in the direction close to the sliding member 20 and causing an obstacle to the movement of the sliding member 20, and make the movement stroke of the locking rod 41 along the Z-axis direction more stable and reliable.

[0133] On this basis, please refer to in combination with Figure 17 and Figure 18 Figure 18 which is a schematic structural diagram of another stop and positioning mechanism 100 provided by the embodiment of the present application. Figure 18 In Figure 18 , the fixed seat 12 and the stop block 11 are in the third position, and the first end 412 of the locking rod 41 is located in the groove 22. The stop and positioning mechanism 100 further includes a base 60. The driving device 50 is arranged on the base 60 to realize the installation and fixation of the driving device 50. The base 60 is provided with an abutting protrusion 61, the second end 422 of the connecting rod 42 abuts against the abutting protrusion 61, and the middle part of the connecting rod 42 is hinged to the fixed seat 12.

[0134] During the process of the fixed seat 12 and the stop block 11 moving from the third position to the fourth position, the driving device 50 drives the fixed seat 12 to move towards the direction close to the base 60, and the connecting rod 42 gradually approaches the abutting protrusion 61. Then the abutting protrusion 61 contacts the second end 422 of the connecting rod 42, the abutting protrusion 61 pushes the second end 422 of the connecting rod 42 to rotate, the second end 422 drives the first end 421 to rotate, the first end 421 drives the second end 414 of the locking rod 41 to move away from the sliding member 20, the second end 414 of the locking rod 41 drives the first end 413 to move away from the sliding member 20, so that the first end 413 disengages from the groove 22. The first boss 415 moves away from the sliding member 20, and the first boss 415 gradually compresses the second elastic member 43.

[0135] During the process of the fixed seat 12 and the stop block 11 moving from the fourth position to the third position, the driving device 50 drives the fixed seat 12 to move away from the base 60, and the second end 422 of the connecting rod 42 disengages from the abutting protrusion 61. The elastic force of the second elastic member 43 pushes the first boss 415 to move towards the direction close to the sliding member 20, so that the first end 413 is inserted into the groove 22. The first end 413 of the locking rod 41 drives the second end 414 to move towards the direction close to the sliding member 20, and the second end 414 of the locking rod 41 drives the first end 421 of the connecting rod 42 to move towards the direction close to the sliding member 20, so that the connecting rod 42 rotates.​

[0136] The abutting protrusion 61 abuts against the second end 422 of the connecting rod 42, so that the connecting rod 42 drives the locking rod 41 to move away from the sliding member 20, so that the second elastic member 43 is gradually compressed. After the abutting protrusion 61 is no longer abutted against the second end 422 of the connecting rod 42, the elastic force of the second elastic member 43 pushes the locking rod 41 to move toward the sliding member 20, so that the first end 413 of the locking rod 41 can be inserted into the groove 22, so that the locking rod 41 can be reset.

[0137] On this basis, please continue to refer to Figure 18 The fixed seat 12 includes a fixed block 124 and a support plate 125, and the fixed block 124 is fixed on the support plate 125. The stop block 11 is slidably connected to the fixed block 124, and the stop block 11 can slide relative to the fixed block 124 along the X-axis direction. The accommodating hole 122 is opened on the fixed block 124. The output end of the driving device 50 is connected to the support plate 125, and the driving device 50 drives the support plate 125 to move along the Z-axis direction. The support plate 125 drives the fixed block 124 to move, and the fixed block 124 drives the stop block 11 to move. The second elastic member 43 abuts between the support plate 125 and the first boss 415, so that the movement of the locking rod 41 along the Z-axis direction can cause the second elastic member 43 to deform, and the locking rod 41 is reset by the elastic force of the second elastic member 43.

[0138] In some embodiments, please refer to Figure 18 , Figure 19 and Figure 20 , Figure 19 A schematic diagram of the structure of a locking assembly provided in an embodiment of the present application is shown in FIG. Figure 20 for Figure 19 The locking assembly 40 further includes a shaft 44, one end of which is fixedly connected to the fixing block 124 to achieve installation and fixing of the shaft 44, and the shaft 44 can move with the fixing block 124. The other end of the shaft 44 is hinged to the connecting rod 42, and the connecting rod 42 can rotate around the shaft 44 to drive the locking rod 41 to move between the third position and the fourth position.

[0139] Based on this, please continue to refer to Figure 18 , Figure 19 and Figure 20 The connecting rod 42 is provided with a mounting groove 423 and a mounting hole 424 . The mounting hole 424 is connected to the mounting groove 423 . The mounting hole 424 penetrates the connecting rod 42 along the X-axis direction. The shaft rod 44 passes through the mounting hole 424 .

[0140] The locking assembly 40 further includes a connecting seat 45, and the connecting seat 45 includes a first connecting portion 451 and a second connecting portion 452 which are connected to each other. The first connecting portion 451 extends along the Z-axis direction, and the second connecting portion 452 extends along the X-axis direction. The first connecting portion 451 extends into the installation groove 423, the shaft rod 44 passes through the first connecting portion 451, and the shaft rod 44 can rotate relative to the first connecting portion 451. The second connecting portion 452 is connected to the fixed block 124 to realize the installation and fixation of the connecting seat 45. By providing the connecting seat 45, the shaft rod 44 is hinged to the fixed block 124, so that the shaft rod 44 can rotate more stably and reliably.

[0141] Exemplarily, the locking assembly 40 may further include a fastener 46. The fastener 46 may be a bolt, and the second connecting portion 452 may be detachably connected to the fixed block 124 through the fastener 46 to fix the second connecting portion 452 to the fixed block 124. Moreover, the detachable connection method facilitates the installation and replacement of the connecting seat 45, making the use of the connecting seat 45 more flexible and convenient.

[0142] In some embodiments, please refer to Figure 21 、 Figure 22 and Figure 23 , Figure 21 which is a schematic structural diagram of the stop block 11 in a stop positioning mechanism 100 provided by an embodiment of the present application when it is in the first position, Figure 22 which is a schematic structural diagram of the stop block 11 in a stop positioning mechanism 100 provided by an embodiment of the present application when it is in the second position, Figure 23 which is a schematic structural diagram of a reset member 70 in a stop positioning mechanism 100 provided by an embodiment of the present application when it is in the reset state. The stop positioning mechanism 100 may further include a reset member 70. The reset member 70 abuts between the stop block 11 and the fixed seat 12, and the reset member 70 extends along the X-axis direction. Exemplarily, the reset member 70 may be a spring, and the spring has the advantages of being convenient for installation and replacement.

[0143] During the process that the workpiece carrier 202 (see Figure 1 ) pushes the stop block 11 to slide from the first position to the second position, the stop block 11 pushes the sliding member 20 to slide. As shown in Figure 22 , the sliding of the sliding member 20 causes the first elastic member 30 to be compressed, and the stop block 11 causes the reset member 70 to be compressed. The first elastic member 30 buffers and absorbs the kinetic energy generated by the workpiece carrier 202, and the locking rod 41 (see Figure 20 ) makes the sliding member 20 only able to slide in the direction close to the fixed seat 12 and not able to slide in the direction away from the fixed seat 12, so that the kinetic energy of the workpiece carrier absorbed by the first elastic member 30 is locked.

[0144] As shown in Figure 23As shown, after the stop block 11 moves to the second position, the locking component 40 still enables the sliding member 20 to slide only in the direction close to the fixed seat 12. The reset member 70 is in a reset state, and the elastic force of the reset member 70 pushes the stop block 11 to slide from the second position to the first position, realizing the quick reset of the stop block 11.

[0145] It can be understood that when the workpiece carrier 202 moves to the specified position, the conveyor belt 201 (see Figure 1 ) stops moving. Most of the kinetic energy of the workpiece carrier 202 is absorbed and locked by the first elastic member 30. However, due to inertia, the workpiece carrier 202 may still move a certain distance in the direction close to the fixed seat 12. The reset member 70 pushes the stop block 11 to slide from the second position to the first position, and the stop block 11 can push the workpiece carrier 202 back to the specified position. By setting the reset member 70, the position accuracy of the workpiece carrier 202 can be higher.

[0146] The reset member 70 with different elastic forces can be flexibly selected according to the weights of the workpiece and the workpiece carrier 202, so that the elastic force of the reset member 70 can push the workpiece carrier 202 and the workpiece back to the specified position.

[0147] Exemplarily, the number of the reset members 70 can be two. The two reset members 70 are respectively located on both sides of the stop block 11 along the Y-axis direction. By setting two reset members 70, the thrust of the reset members 70 is increased, and the force on the stop block 11 can also be made more uniform.

[0148] In some embodiments, please refer to Figure 24 , Figure 24 which is a schematic structural diagram of another stop and positioning mechanism 100 provided by the embodiment of the present application. The stop and positioning mechanism 100 further includes a guide rod 111. The axis of the guide rod 111 is parallel to the first direction, and the guide rod 111 extends along the X-axis direction. A guide hole 126 is formed in the fixed seat 12, and the guide hole 126 extends along the X-axis direction. One end of the guide rod 111 is connected to the stop block 11, and the guide rod 111 can move together with the stop block 11. The other end of the guide rod 111 extends into the guide hole 126, and the reset member 70 is sleeved on the guide rod 111. The guide rod 111 can guide the deformation of the reset member 70 along the X-axis direction, reduce the sway of the reset member 70 along the Z-axis direction and the Y-axis direction, and make the deformation of the reset member 70 along the X-axis direction more stable and reliable.

[0149] On this basis, please continue to refer to Figure 24 , the stop and positioning mechanism 100 further includes an adsorption component 80. The adsorption component 80 is located on the surface of the stop block 11 away from the fixed seat 12. The adsorption component 80 is used to adsorb the workpiece carrier 202 (see Figure 1) so that the workpiece carrier 202 moves together with the stop block 11, enabling the stop block 11 to more conveniently push the workpiece carrier 202 back to the specified position.

[0150] Please continue to refer to Figure 24 , the stop positioning mechanism 100 may further include a first buffer pad 112, and the first buffer pad 112 is located on the surface of the stop block 11 away from the fixed seat 12. By providing the first buffer pad 112 to buffer between the stop block 11 and the workpiece carrier 202, the impact force between the workpiece carrier 202 and the stop block 11 is reduced, making the resilience of the workpiece carrier 202 smaller. At the same time, the first buffer pad 112 can also prevent damage to the workpiece carrier 202 or the stop block 11 caused by excessive impact force between the workpiece carrier 202 and the stop block 11, and extends the service life of the workpiece carrier 202 and the stop block 11.

[0151] Please continue to refer to Figure 24 , the stop positioning mechanism 100 may further include a second buffer pad 23, and the second buffer pad 23 is provided at the end of the sliding member 20 away from the fixed seat 12. By providing the second buffer pad 23 to buffer between the sliding member 20 and the stop block 11, the impact force between the sliding member 20 and the stop block 11 is reduced, preventing damage to the sliding member 20 or the stop block 11 caused by excessive impact force between the sliding member 20 and the stop block 11, and extending the service life of the sliding member 20 and the stop block 11.

[0152] In some embodiments, please refer to Figure 25 and Figure 26 , Figure 25 is a schematic structural diagram of the stop component 10 in a stop positioning mechanism provided by an embodiment of the present application, Figure 26 is Figure 25 a disassembled schematic diagram of the stop component 10 in. The fixed seat 12 includes a fixed block 124, the fixed block 124 includes a first part 1241 and a second part 1242, the first part 1241 is fixed on the second part 1242, and the first part 1241 and the second part 1242 are distributed along the Z-axis direction. The sliding groove 121 is opened on the first part 1241, and the sliding member 20 can slide relative to the sliding groove 121 along the X-axis direction.

[0153] The stop block 11 includes an abutting portion 113 and two sliding portions 114, the two sliding portions 114 are distributed along the Y-axis direction, and the two sliding portions 114 are respectively fixed at both ends of the abutting portion 113. The stop block 11 is arranged on the second part 1242, the abutting portion 113 and the first part 1241 are distributed along the X-axis direction, and the two sliding portions 114 are respectively located on both sides of the first part 1241.

[0154] During the process of the workpiece carrier 202 pushing the abutting portion 113 to move in the X-axis direction, the two sliding portions 114 slide relative to both sides of the first portion 1241. The two sliding portions 114 and the first portion 1241 cooperate with each other for guiding and limiting, so that the stop block 11 can stably slide relative to the fixed block 124 in the X-axis direction, preventing the stop block 11 from wobbling in the Y-axis direction.

[0155] Based on this, please continue to refer to Figure 25 and Figure 26 The fixed block 124 further includes two third portions 1243. The two third portions 1243 are arranged in one-to-one correspondence with the two sliding portions 114, and the sliding portion 114 is located between the first portion 1241 and the corresponding third portion 1243. That is to say, the first portion 1241, the second portion 1242 and the third portion 1243 jointly enclose a sliding track 1244. The sliding portion 114 can slide relative to the corresponding sliding track 1244, and the sliding track 1244 can play a guiding role in the sliding of the sliding portion 114 in the X-axis direction, improving the stability and reliability of the sliding of the sliding portion 114 in the X-axis direction, and making the movement of the stop block 11 in the X-axis direction more reliable.

[0156] Please continue to refer to Figure 25 and Figure 26 A guiding groove 1245 and a guiding protrusion 115 are provided between the opposite surfaces of the third portion 1243 and the sliding portion 114. One of the guiding groove 1245 and the guiding protrusion 115 is provided on the third portion 1243, and the other of the guiding groove 1245 and the guiding protrusion 115 is provided on the sliding portion 114.

[0157] As Figure 25 and Figure 26 shown, the guiding groove 1245 is provided on the third portion 1243, and the guiding protrusion 115 is provided on the sliding portion 114. In another embodiment, the guiding groove 1245 can also be provided on the sliding portion 114, and the guiding protrusion 115 can also be provided on the third portion 1243.

[0158] The guiding groove 1245 extends in the X-axis direction, and the guiding protrusion 115 extends into the guiding groove 1245. By the cooperation of the guiding protrusion 115 and the guiding groove 1245, the contact area between the sliding portion 114 and the third portion 1243 is increased, so that the sliding portion 114 can slide more stably relative to the third portion 1243, further improving the stability and reliability of the sliding of the sliding portion 114 in the X-axis direction, thereby realizing the improvement of the stability and reliability of the sliding of the stop block 11.

[0159] On this basis, please continue to refer to Figure 25 and Figure 26, the stopping block 11 further includes a limiting portion 116, and the limiting portion 116 is fixed to one end of the sliding portion 114 away from the abutting portion 113. When the stopping block 11 is in the first position, the limiting portion 116 abuts against the side of the third part 1243 away from the abutting portion 113. By providing the limiting portion 116 to limit the movement of the stopping block 11 from the second position to the first position, it is avoided that the workpiece carrier 202 continues to move away from the fixed seat 12 after the stopping block 11 reaches the first position, thereby improving the position accuracy of the workpiece carrier 202 staying.
