Technical Field

[0001] The utility model relates to the technical field of automatic loading and unloading of workpieces, in particular to an automatic loading and unloading tooling and an automatic welding device. Background Art

[0002] During the automatic welding process, a bearing plate is required to load a workpiece plate into a welding device for welding, and then the workpiece plate is taken out from the bearing plate after welding. In the prior art, in order to ensure the fixed position of the workpiece plate during the welding process, the bearing plate is designed to include a bottom plate and a pressing plate, and the ends of the bottom plate and the pressing plate are hinged. When it is necessary to fix the workpiece plate, the workpiece plate is placed in the bearing plate, and the pressing plate is manually driven to rotate along the hinged end to abut against the workpiece position. By fixing the pressing plate on the bearing plate, the fixing of the workpiece plate can be achieved. When it is necessary to take out the workpiece plate, it is necessary to manually rotate the pressing plate to a position where it is separated from the bearing plate, so that the pressing plate is away from the workpiece plate, and then the workpiece plate is taken out.

[0003] In view of the unique structure of the bearing plate, in the prior art, before and after the automatic welding process, it is necessary to manually operate to open or close the pressing plate to realize the loading and unloading operations of the workpiece plate. Manually opening or closing the pressing plate has the defect of time-consuming and laborious, and it is urgent to find a device that can automatically open and close the bearing plate to realize automatic loading and unloading after the automatic welding process. Summary of the Utility Model

[0004] To overcome the problems existing in the related art, one of the purposes of the utility model is to provide an automatic loading and unloading tooling, which can realize the rotational separation of the bearing plate and the pressing plate through the mutual cooperation between the pressing part and the clamping and flipping part, thereby realizing the automatic opening or closing of the bearing plate, avoiding the waste of human resources, improving the automatic loading and unloading level of workpieces, and further improving the processing efficiency of workpieces.

[0005] An automatic loading and unloading tooling is used for automatically loading and unloading workpieces loaded on a bearing plate; the bearing plate includes a bottom plate and a pressing plate, the ends of the pressing plate and the bottom plate are hinged, and the workpiece is placed between the bottom plate and the pressing plate;

[0006] The automatic loading and unloading tooling includes: a pressing part and a clamping and flipping part, the clamping and flipping part is hinged to the pressing part, the pressing part is used for fixing the bottom plate, and the clamping and flipping part is used for clamping the pressing plate and driving the pressing plate to rotate along the hinged part at the ends of the clamping and flipping part and the pressing part, so that the pressing plate is separated from or abuts against the bottom plate.

[0007] Through the flipping of the clamping and flipping part in this application, the automatic opening and closing of the pressing plate can be achieved, avoiding waste of human resources, improving the automation level of workpiece loading and unloading, and thus improving the processing efficiency of workpieces.

[0008] In a preferred technical solution of the present utility model, the clamping and flipping part includes a clamping assembly, the clamping assembly includes clamping jaws, and the clamping jaws are connected to a clamping driving member.

[0009] In this application, the clamping and flipping part needs to simultaneously realize the clamping and flipping functions of the pressing plate, that is, it is necessary to clamp and fix the pressing plate through the clamping assembly, and then drive the pressing plate and the clamping assembly to flip together through the flipping assembly to ensure that the pressing plate can still be firmly clamped during the flipping process. Specifically, the clamping assembly includes clamping jaws and a clamping driving member, and the clamping driving member can drive the clamping jaws to move towards or away from the pressing plate to realize the fastening and loosening of the pressing plate; only when the clamping jaws clamp the pressing plate, the flipping assembly will drive the clamping assembly and the pressing plate to flip. If the clamping jaws do not clamp and fasten the pressing plate, the flipping assembly will not perform the flipping operation. This can ensure that during the flipping process of the flipping assembly, the clamping assembly and the pressing plate are an integral structure, ensuring that the pressing plate is flipped while being fastened, avoiding the pressing plate detaching from the flipping assembly during the flipping process, and improving the efficiency of opening and closing the pressing plate.

[0010] In a preferred technical solution of the present utility model, the clamping and flipping part further includes a flipping assembly, the flipping assembly includes a flipping member and a flipping driving member, the flipping member is arranged on the side of the clamping jaws away from the pressing plate, and the clamping assembly is fixedly connected to the flipping member, and the output end of the flipping driving member is connected to the flipping member.

[0011] The function of the flipping member in this application is to flip the clamping jaws and the pressing plate clamped by them. Specifically, the flipping member is arranged on the side of the clamping jaws away from the pressing plate. For example, if the clamping jaws clamp the left and right sides of the pressing plate, the flipping member is located on the left and right sides of the clamping jaws away from the pressing plate. For example, if the clamping jaws clamp the upper and lower sides of the pressing plate, the flipping member is located on the upper and lower sides of the clamping jaws away from the pressing plate. Through this setting, it is ensured that the object of action of the flipping member is the clamping jaws and the pressing plate clamped by the clamping jaws. Further, in this application, the flipping driving member drives the flipping member to flip, so as to realize the flipping of the pressing plate relative to the hinge end of the bottom plate, and thus realize the opening or closing of the pressing plate relative to the bottom plate.

[0012] In a preferred technical solution of the present utility model, the flipping assembly includes two relatively arranged flipping members and a connecting shaft connecting the ends of the two flipping members, and the axis line of the connecting shaft is connected to the output end of the flipping driving member.

[0013] The flipping driving member can be, for example, a stepping motor or other structures. When the flipping driving member operates, the connecting shaft connected to the output end of the flipping driving member rotates, and the rotation of the connecting shaft can drive the two flipping members at its end to flip. In this application, there are two flipping members, which respectively fasten the whole clamping assembly and the pressing plate from two opposite directions and drive them to flip. Corresponding to the two flipping plates, the clamping jaws can also be set to two, and the two flipping members are respectively located on the side of the clamping jaws away from the pressing plate; through the corresponding setting of the clamping jaws and the flipping members, the fastening effect of the clamping assembly on the pressing plate can be improved, and the fastening effect of the flipping assembly on the clamping assembly and the pressing plate clamped by it can also be improved, thereby ensuring the smooth flipping of the pressing plate relative to the bottom plate.

[0014] In a preferred technical solution of the present utility model, two clamping jaws are arranged oppositely, and the two clamping jaws are respectively located on the side of the flipping member close to the pressing plate; one of the clamping jaws is fixedly connected to the flipping member, and the other clamping jaw is connected to the clamping driving member.

[0015] In this application, the two clamps are arranged oppositely to clamp the pressing plate from opposite sides respectively. It should be noted that in this application, two clamping jaws can be set to be connected to the clamping driving member at the same time, or only one of the clamping jaws can be set to be connected to the clamping driving member, while the other clamping jaw remains stationary. When the two clamping jaws are connected to the clamping driving member at the same time, the clamping driving member drives the two clamping jaws to move towards or away from the pressing plate at the same time to loosen or fasten the pressing plate. When one of the clamping jaws is connected to the clamping driving member, one side of the pressing plate and its corresponding clamping jaw are stationary, and the clamping jaw on the other side moves towards or away from the pressing plate to loosen or fasten the pressing plate. Further, when both clamping jaws can move, they can be connected to the same clamping driving member at the same time, or they can be respectively connected to different clamping driving members.

[0016] In a preferred technical solution of the present utility model, the pressing part includes two oppositely arranged baffles. The baffles are of an L-shaped structure, and the minimum distance between the two baffles is less than or equal to the width of the bottom plate; the two flipping members are respectively located in the two baffles.

[0017] The openings in the two L-shaped baffles are arranged relative to each other. The function of the baffles is to fix the bottom plate, that is, the bottom plate can be placed under the baffle, and the minimum spacing between the two baffles is set to be less than or equal to the width of the bottom plate. Here, the width of the bottom plate refers to the size of the bottom plate in the same direction as the minimum spacing between the two baffles. This ensures that the two bottom plates are respectively in contact with both sides of the bottom plate in the width direction to achieve fixation of the bottom plate. In this application, the two flip parts can be respectively set in the two baffles, and correspondingly, the two clamping claws are also respectively set in the two baffles. When the two baffles fix the two sides of the width of the bottom plate, the clamping claws fasten the press plate from both sides in the width direction of the press plate, and the flip part then fastens the clamping claws and the press plate clamped by them.

[0018] In a preferred technical solution of the present invention, the two baffles are located above the transmission line, and the transmission line is used to transmit the carrier plate.

[0019] The transfer line can be located at the inlet or outlet of a processing station, used to transport the carrier plate and the workpiece above it into or out of the processing station. When the transfer line is located at the inlet, the flip assembly drives the clamping jaws and the clamping plate they hold toward the base plate, ensuring that the workpiece in the base plate is secured by the clamping plate and the base plate. When the transfer line is located at the outlet, the flip assembly drives the clamping jaws and the clamping plate they hold away from the base plate, ensuring that the workpiece in the base plate is released and achieving automatic workpiece unloading.

[0020] In a preferred technical solution of the present invention, the space between the two baffles is hollowed out and an ejection assembly is provided; a hollow workpiece placement position is provided in the bottom plate; the ejection assembly is arranged on the side of the supporting plate away from the baffle, and the ejection assembly can drive the workpiece on the supporting plate to move in a direction away from the supporting plate.

[0021] The base plate of the present application is provided with a hollowed-out workpiece placement area, and the cross-sectional area of the hollowed-out workpiece placement area is smaller than that of the workpiece. At the same time, the side of the hollowed-out workpiece placement area of the base plate is provided with a placement groove, and the cross-sectional area of the placement groove is equal to the cross-sectional area of the workpiece. This ensures that when the workpiece is placed in the placement groove, the bottom side abuts against the bottom of the placement groove, and the center position of the workpiece is located in the hollowed-out structure. Correspondingly, the present application can provide an ejection assembly below the base plate. When the flip assembly drives the pressing plate to separate from the base plate, the ejection assembly extends, allowing the workpiece to be separated from the base plate, so that it can be removed manually or by a robot.

[0022] In a preferred technical solution of the present invention, a clamping sensor for detecting whether the clamping is in place is provided on the side of the clamping claw facing the pressing plate; and a position sensor for detecting whether the supporting plate is in place is provided in the pressing portion.

[0023] The clamping sensor can be, for example, a pressure sensor or the like. It is arranged in the jaw and used to detect the relative acting force between the jaw and the pressing plate. Only when the relative acting force reaches the preset value can it be ensured that the jaw effectively fastens the pressing plate. Specifically, the clamping sensor can be arranged in only one of the jaws or in both jaws simultaneously.

[0024] The in - place sensor is used to detect whether the carrier plate has moved below the pressing part. Specifically, the in - place sensor can be installed on the side of the pressing part close to the transmission line. Only when the in - place sensor detects that the carrier plate has moved below the pressing part will the jaws extend to fasten the pressing plate, and then the flipping assembly will drive the clamping assembly and the pressing plate it holds to flip. Otherwise, the clamping and flipping part will not operate.

[0025] The second object of this application is to provide an automatic welding device, including an automatic loading and unloading tooling as described above.

[0026] The automatic welding device of this application can not only realize the automation of welding, but also improve the automation level of PCB board loading and unloading, avoid waste of human resources, improve the automation level of the automatic welding device, and further improve the efficiency of automatic welding.

In the initial state of the carrier plate, the bottom plate and the pressing plate are separated. At this time, the pressing part fixes the bottom plate, and the workpiece is placed in the carrier plate.

[0041] Embodiment 1

[0042] As Figures 1 - 6 shown, an automatic loading and unloading tooling is used for automatically loading and unloading workpieces loaded on a carrier plate; wherein, the carrier plate includes a bottom plate 21 and a pressing plate 22, the end of the pressing plate 22 is hinged to the bottom plate 21, and the workpiece is placed between the bottom plate 21 and the pressing plate 22; the automatic loading and unloading tooling includes a pressing part and a clamping and flipping part, the clamping and flipping part is hinged to the pressing part, the pressing part is used to fix the bottom plate 21, and the clamping and flipping part is used to clamp the pressing plate 22 and drive the pressing plate 22 to rotate along the hinged joint of the ends of the clamping and flipping part and the pressing part, so that the pressing plate 22 and the bottom plate 21 are separated or abutted.

[0043] In the initial state of the carrier plate in the present application, the bottom plate 21 and the pressing plate 22 are separated. At this time, the pressing part fixes the bottom plate 21, and the workpiece is placed in the carrier plate. The clamping and flipping part drives the pressing plate 22 to rotate to a position where it abuts against the workpiece in the bottom plate 21 and fixes the pressing plate 22, so that the bottom plate 21 and the pressing plate 22 can fix the workpiece; after the workpiece completes the processing procedure, the pressing part fixes the bottom plate 21, the clamping and flipping part drives the pressing plate 22 to rotate to a position away from the bottom plate 21, and the workpiece in the bottom plate 21 is taken out, so that the automatic feeding and discharging of the workpiece can be realized.

[0044] In the present application, through the flipping of the clamping and flipping part, the automatic opening and closing of the pressing plate 22 can be realized, avoiding waste of human resources, improving the automatic loading and unloading level of the workpiece, and further improving the processing efficiency of the workpiece.

[0045] In this application, the clamping and flipping part needs to achieve two functions. One is to clamp and fasten the pressing plate 22, and the other is to drive the pressing plate 22 to flip. Flipping means rotating around the hinge end of the pressing plate 22 and the bottom plate 21, so that the pressing plate 22 abuts against the bottom plate 21 or the pressing plate 22 moves away from the bottom plate 21, thereby realizing the fixation or loosening of the workpiece in the carrier plate.

[0046] In the carrier plate of this application, there is a placement position for placing the workpiece. The specific workpiece is in a plate-like structure, such as a PCB board, etc. Specifically, a placement groove or a combination of a hollow structure and a groove can be set in the carrier plate to realize the placement of the workpiece. At the same time, with the abutment of the pressing plate 22, the fixation of the workpiece in the placement position can be realized.

[0047] Embodiment 2

[0048] As Figures 1 - 6 shown, an automatic loading and unloading tooling is used for automatically loading and unloading the workpiece loaded on the carrier plate. Among them, the carrier plate includes a bottom plate 21 and a pressing plate 22. The ends of the pressing plate 22 and the bottom plate 21 are hinged, and the workpiece is placed between the bottom plate 21 and the pressing plate 22. The automatic loading and unloading tooling includes a pressing part and a clamping and flipping part. The clamping and flipping part is hinged to the pressing part. The pressing part is used to fix the bottom plate 21, and the clamping and flipping part is used to clamp the pressing plate 22 and drive the pressing plate 22 to rotate along the hinge joint of the ends of the clamping and flipping part and the pressing part, so that the pressing plate 22 and the bottom plate 21 are separated or abutted.

[0049] Specifically, the clamping and flipping part includes a clamping component and a flipping component. The clamping component includes a clamping jaw 14, and the clamping jaw 14 is connected to a clamping driving part 15.

[0050] In this application, the clamping and flipping part needs to simultaneously realize the clamping and flipping functions of the pressing plate 22, that is, it is necessary to clamp and fix the pressing plate 22 through the clamping component, and then drive the pressing plate 22 and the clamping component to flip together through the flipping component to ensure that the clamping of the pressing plate 22 can still be maintained during the flipping process. Specifically, the clamping component includes a clamping jaw 14 and a clamping driving part 15, and the clamping driving part 15 can drive the clamping jaw 14 to move towards or away from the pressing plate 22 to realize the fastening and loosening of the pressing plate 22. Only when the clamping jaw 14 clamps the pressing plate 22, the flipping component will drive the clamping component and the pressing plate 22 to flip. If the clamping jaw 14 does not clamp and fasten the pressing plate 22, the flipping component will not perform the flipping operation. This can ensure that during the flipping process of the flipping component, the clamping component and the pressing plate 22 are an integral structure, ensuring that the pressing plate 22 is flipped under the condition of being fastened, avoiding the pressing plate 22 detaching from the flipping component during the flipping process, and improving the opening and closing efficiency of the pressing plate 22.

[0051] Further, the flipping assembly of the present application includes a flipping member 12 and a flipping driving member 13. The flipping member 12 is disposed on a side of the clamping jaw 14 away from the pressing plate 22, and the clamping assembly is fixedly connected to the flipping member 12. The output end of the flipping driving member 13 is connected to the flipping member 12.

[0052] The function of the flipping member 12 in the present application is to flip the clamping jaw 14 and the pressing plate 22 clamped thereby. Specifically, the flipping member 12 is disposed on a side of the clamping jaw 14 away from the pressing plate 22. For example, if the clamping jaw 14 clamps the left and right sides of the pressing plate 22, the flipping member 12 is located on the left and right sides of the clamping jaw 14 away from the pressing plate 22. If the clamping jaw 14 clamps the upper and lower sides of the pressing plate 22, the flipping member 12 is located on the upper and lower sides of the clamping jaw 14 away from the pressing plate 22. Through this setting, it is ensured that the object of action of the flipping member 12 is the clamping jaw 14 and the pressing plate 22 clamped by the clamping jaw 14. Further, in the present application, the flipping driving member 13 drives the flipping member 12 to flip, so that the flipping of the pressing plate 22 relative to the hinged end of the bottom plate 21 can be realized, and further the opening or closing of the pressing plate 22 relative to the bottom plate 21 can be realized.

[0053] Further, the flipping assembly includes two flipping members 12 disposed oppositely and a connecting shaft 18 connecting the ends of the two flipping members 12. The axis line of the connecting shaft 18 is connected to the output end of the flipping driving member 13.

[0054] The flipping driving member 13 can be, for example, a stepping motor or the like. When the flipping driving member 13 operates, the connecting shaft 18 connected to the output end of the flipping driving member 13 rotates, and the rotation of the connecting shaft 18 can drive the two flipping members 12 at its ends to flip. In the present application, there are two flipping members 12, which respectively fasten the whole of the clamping assembly and the pressing plate 22 from two opposite directions and drive them to flip. Correspondingly, the clamping jaws 14 can also be provided in two, and the two flipping members 12 are respectively located on a side of the clamping jaws 14 away from the pressing plate 22; through the corresponding setting of the clamping jaws 14 and the flipping members 12, the fastening effect of the clamping assembly on the pressing plate 22 can be improved, and the fastening effect of the flipping assembly on the clamping assembly and the pressing plate 22 clamped thereby can also be improved, thereby ensuring the smooth flipping of the pressing plate 22 relative to the bottom plate 21.

[0055] Further, two clamping jaws 14 are disposed oppositely, and the two clamping jaws 14 are respectively located on a side of the flipping member 12 close to the pressing plate 22; one of the clamping jaws 14 is fixedly connected to the flipping member 12, and the other clamping jaw 14 is connected to the clamping driving member 15.

[0056] In this application, the two clamps are arranged oppositely and are used to clamp the pressing plate 22 from opposite sides respectively. It should be noted that in this application, two jaws 14 can be set to be connected to the clamping driving member 15 at the same time, or only one of the jaws 14 can be set to be connected to the clamping driving member 15, while the other jaw 14 remains fixed. When the two jaws 14 are connected to the clamping driving member 15 at the same time, the clamping driving member 15 drives the two jaws 14 to move towards or away from the pressing plate 22 simultaneously to loosen or fasten the pressing plate 22. When one of the jaws 14 is connected to the clamping driving member 15, one side of the pressing plate 22 and its corresponding jaw 14 remain fixed, and the jaw 14 on the other side moves towards or away from the pressing plate 22 to loosen or fasten the pressing plate 22. Further, when both jaws 14 can move, they can be connected to the same clamping driving member 15 at the same time, or can be connected to different clamping driving members 15 respectively.

[0057] Further, the pressing part includes two oppositely arranged baffles 11. The baffle 11 is of an L-shaped structure, and the minimum distance between the two baffles 11 is less than or equal to the width of the bottom plate 21; the two flipping members 12 are respectively located in the two baffles 11.

[0058] The openings in the two L-shaped baffles 11 are arranged oppositely. The function of the baffle 11 is to fix the bottom plate 21, that is, the bottom plate 21 can be placed below the baffle 11, and the minimum distance between the two baffles 11 is set to be less than or equal to the width of the bottom plate 21. Here, the width of the bottom plate 21 refers to the size of the bottom plate 21 in the same direction as the minimum distance between the two baffles 11. Only in this way can it be ensured that the two bottom plates 21 respectively abut against both sides in the width direction of the bottom plate 21 to realize the fixation of the bottom plate 21. In this application, the two flipping members 12 can be respectively arranged in the two baffles 11. Correspondingly, the two jaws 14 are also respectively arranged in the two baffles 11. When the two baffles 11 fix both sides of the width of the bottom plate 21, the jaws 14 fasten the pressing plate 22 from both sides in the width direction of the pressing plate 22, and the flipping member 12 further fastens the jaws 14 and the pressing plate 22 held by them.

[0059] Further, the two baffles 11 are located above the transmission line, and the transmission line is used to transmit the carrier plate.

[0060] The transmission line can be located at the inlet or outlet of a processing station, used to transport the carrier plate and the workpiece above it into or out of the processing station. When the transmission line is located at the inlet, the flip assembly drives the clamping jaws 14 and the clamping plate 22 held therein toward the base plate 21, ensuring that the workpiece in the base plate 21 is secured by the clamping plate 22 and the base plate 21. When the transmission line is located at the outlet, the flip assembly drives the clamping jaws 14 and the clamping plate 22 held therein toward the base plate 21, ensuring that the workpiece in the base plate 21 is released, thereby achieving automatic unloading of the workpiece.

[0061] Furthermore, the space between the two baffles 11 is hollowed out and an ejection assembly is provided; a hollow workpiece placement position is provided in the bottom plate 21; the ejection assembly is arranged on the side of the supporting plate away from the baffle 11, and the ejection assembly can drive the workpiece on the supporting plate to move in a direction away from the supporting plate.

[0062] The base plate 21 of the present application is provided with a hollowed-out workpiece placement position, and the hollowed-out cross-sectional area is smaller than the cross-sectional area of the workpiece. At the same time, the side of the hollowed-out workpiece placement position of the base plate 21 is provided with a placement groove, and the cross-sectional area of the placement groove is equal to the cross-sectional area of the workpiece, ensuring that when the workpiece is placed in the placement groove, the bottom side abuts against the bottom of the placement groove, and the center position of the workpiece is located in the hollow structure. Correspondingly, the present application can set an ejection component below the base plate 21. When the flip assembly drives the pressing plate 22 to separate from the base plate 21, the ejection component extends, allowing the workpiece to be separated from the base plate 21, so that it can be removed manually or by a robot.

[0063] Furthermore, the clamping jaw 14 of the present application is provided with a clamping sensor on the side facing the pressing plate 22 for detecting whether the clamping is in place; and the pressing portion is provided with an in-place sensor for detecting whether the supporting plate is in place.

[0064] The clamping sensor, for example, a pressure sensor, is disposed in the clamping jaw 14 to detect the relative force between the clamping jaw 14 and the pressing plate 22. Only when the relative force reaches a preset value can the clamping jaw 14 be guaranteed to have effectively tightened the pressing plate 22. Specifically, the clamping sensor can be disposed in only one of the clamping jaws 14 or in both.

[0065] The in-place sensor is used to detect whether the carrier plate moves to the bottom of the pressing part. Specifically, the in-place sensor can be installed on the side of the pressing part close to the transmission line. Only when the in-place sensor detects that the carrier plate moves to the bottom of the pressing part, the clamping claw 14 will extend to tighten the pressing plate 22, and then the flipping assembly will drive the clamping assembly and the clamped pressing plate 22 to flip, otherwise, the clamping and flipping part will not operate.

[0066] Example 3

[0067] As shown Figures 1 - 6 in the figure, an automatic loading and unloading tooling is used for automatically loading and unloading workpieces loaded on a carrier plate. The carrier plate includes a bottom plate 21 and a pressing plate 22. The end of the pressing plate 22 is hinged to the end of the bottom plate 21, and the workpiece is placed between the bottom plate 21 and the pressing plate 22. The automatic loading and unloading tooling includes a pressing part and a clamping and flipping part. The clamping and flipping part is hinged to the pressing part. The pressing part is used to fix the bottom plate 21, and the clamping and flipping part is used to clamp the pressing plate 22 and drive the pressing plate 22 to rotate along the hinged joint at the end of the clamping and flipping part and the pressing part, so that the pressing plate 22 and the bottom plate 21 are separated or abutted.

[0068] Specifically, the pressing part includes two oppositely arranged baffles 11. The baffles 11 are of an L-shaped structure, and the openings in the two L-shaped baffles 11 are oppositely arranged. As Figure 1 shown in the figure, the bottoms of the two baffles 11 are horizontally opposite, and the tops of the two baffles 11 are vertically opposite. The two baffles 11 are respectively located above the transmission line, and the transmission line is used to transmit the carrier plate. In this application, the two baffles 11 can be set as a liftable structure. When it is necessary to fix the carrier plate in the transmission line, the two baffles 11 descend simultaneously to fix the bottom plate 21 in the carrier plate. When the flipping of the pressing plate 22 and the bottom plate 21 is completed and the carrier plate in the transmission line needs to continue to move along the transmission line, the two baffles 11 rise simultaneously to reserve enough space for the carrier plate to continue to be transmitted.

[0069] In this embodiment, it is defined that the length direction of the bottom plate 21 is the same as the transmission direction of the transmission line, and the minimum distance between the two baffles 11 is less than or equal to the width of the bottom plate 21; only in this way can it be ensured that the baffles 11 fix the two sides of the bottom plate 21 in the width direction. And when the baffles 11 fix the bottom plate 21, the transmission line is stationary, and when the baffles 11 rise, the transmission line resumes transmission.

[0070] In this application, the clamping and flipping part includes a clamping component and a flipping component. The flipping component includes two oppositely arranged flipping pieces 12, a connecting shaft 18 connecting the ends of the two flipping pieces 12, and a flipping driving part 13. Among them, the two flipping pieces 12 are oppositely arranged in the two baffles 11. The ends of the two flipping pieces 12 are respectively connected to both ends of the connecting shaft 18, and the axis line of the connecting shaft 18 is connected to the output end of the flipping driving part 13. The flipping driving part 13 is specifically a stepping motor, and the flipping driving part 13 is fixed in one of the baffles 11. When the flipping driving part 13 operates, it can drive the connecting shaft 18 to rotate, and then drive the flipping pieces 12 at both ends of the connecting shaft 18 to flip.

[0071] The clamping assembly of the present application includes a jaw 14 and a clamping drive 15. In this embodiment, there is only one jaw 14, and the jaw 14 is disposed on one side of one of the flipping members 12 close to the other flipping member 12. That is to say, defining the side where the two flipping members 12 face each other as the inner side of the flipping member 12, then the jaw 14 is disposed on the inner side of one of the flipping members 12, and the other flipping member 12 can be used as both the jaw 14 and the flipping member 12 simultaneously, without the need to provide the jaw 14 separately. The jaw 14 is connected to the clamping drive 15. The clamping drive 15 can be a cylinder, and the jaw 14 is slidably connected to the flipping member 12. When the clamping drive 15 extends, the jaw 14 can move towards the direction close to the other flipping member 12 to achieve the fastening of the pressing plate 22 between the two flipping members 12.

[0072] In the present application, the position of the flipping member 12 is fixed and cannot achieve the fastening and loosening of the pressing plate 22. However, the jaw 14 located inside the flipping member 12 can move. Under the action of the clamping drive 15, it can cooperate with the other flipping member 12 to achieve the fastening and loosening of the pressing plate 22.

[0073] When the flipping drive 13 drives the flipping assembly, the clamping assembly, and the pressing plate 22 to flip through the connecting shaft 18, the flipping member 12, the jaw 14, the clamping drive 15, and the pressing plate 22 form a unified whole and will flip simultaneously with the flipping member 12.

[0074] An in-place sensor for detecting whether the carrier plate is in place is provided in the pressing portion. The in-place sensor can specifically be a photoelectric sensor, etc. The in-place sensor can be installed at the bottom of the baffle 11. Only when the in-place sensor detects that the carrier plate has moved below the baffle 11, the jaw 14 will extend to fasten the pressing plate 22.

[0075] A clamping sensor for detecting whether the clamping is in place is provided on the side of the jaw 14 facing the pressing plate 22. The clamping sensor can be, for example, a pressure sensor, etc. It is disposed in the jaw 14 and is used to detect the relative acting force between the jaw 14 and the pressing plate 22. Only when the relative acting force reaches a preset value, the flipping drive 13 will operate; otherwise, the tooling will alarm.
