The linkage shaft 628 is fixedly connected at an end close to the working frame 100 with an abutting plate 641. The telescopic shaft 639 is hingedly connected at an end close to the working frame 100 with a driving lever 631. A driven lever 632 is hingedly connected at an end away from a prying head 638 to an end of the driving lever 631 away from the telescopic shaft 639.

[0064] It can be understood that when the first driving cylinder 624 drives the linkage shaft 628 to extend or retract, the abutting plate 641 is driven to move axially relative to the grabbing sleeve 623, thereby releasing the skin bowl 420 in the grabbing sleeve 623. When the second driving cylinder 627 drives the telescopic shaft 639 to extend or retract, the driving lever 631 drives the driven lever 632 to swing relative to the grabbing sleeve 623, and the prying head 638 is driven to push the skin bowl 420 in the grabbing sleeve 623 radially.

[0065] As shown in FIGS. 8 and 9, the adapter cylinder 622 is fixedly provided at an end away from the working frame 100 with a transition bracket 621, and the second driving cylinder 627 is fixedly arranged at an end of the transition bracket 621 away from the working frame 100. The second driving cylinder 627 is fixedly provided at an end away from the transition bracket 621 with an adapter seat 625, and the first driving cylinder 624 is fixedly arranged at an end of the adapter seat 625 away from the second driving cylinder 627. The extending end of the first driving cylinder 624 is fixedly connected with an adapter bracket 626 slidingly connected with the adapter seat 625 and the transition bracket 621, respectively, and the linkage shaft 628 is fixedly arranged on the adapter bracket 626.

[0066] As shown in FIGS. 8, 10 and 11, the adapter cylinder 622 is fixedly provided at an end close to the working frame 100 with an adapter 629, and a positioning frame 630 is fixedly arranged at an end of the adapter 629 close to the working frame 100.

[0067] As shown in FIGS. 8, 11 and 12, the linkage shaft 628 is fixedly provided at an end close to the working frame 100 with a synchronous plate 640, and the abutting plate 641 is fixedly arranged on the synchronous plate 640.

[0068] As shown in FIG. 13, the abutting plate 641 is provided with two stroke grooves 644 extending axially along the grabbing sleeve 623, and the two stroke grooves 644 are symmetrical about a central axis of the grabbing sleeve 623.

[0069] The shaping plate 645 is provided with a sliding convex part, and the sliding convex parts of the two shaping plates 645 are respectively connected with the stroke grooves 644 at corresponding positions in a sliding mode.

[0070] As shown in FIG. 13, the abutting plate 641 is fixedly provided with two fixed blocks 646 which are symmetrical about the central axis of the grabbing sleeve 623, and the two fixed blocks 646 are respectively located at corresponding positions of the two shaping plates 645. Among them, the shaping plate 645 and the corresponding fixed block 646 are fixedly provided with an elastic element 647.

[0071] It can be understood that when the shaping plate 645 moves relative to the abutting plate 641 in the axial direction of the grabbing sleeve 623, the elastic element 647 can accumulate elastic potential energy, which can not only ensure the reliability of the force of the shaping plate 645 on the leather cup 420, but also realize the automatic reset of the shaping plate 645.

[0072] The elastic element 647 can be a spring, a clasp or an elastic rubber, as long as it can realize the elastic sliding of the shaping plate 645 relative to the abutting plate 641, and details are not repeated here.

[0073] As shown in FIGS. 1 and 2, the valve block tooling includes a transposition guide rail 310 fixedly arranged on the working frame 100, and the assembly table 320 is arranged in a sliding mode on the transposition guide rail 310.

[0074] The embodiment of the present application provides a leather cup assembling method, which is suitable for the leather cup assembling device in the above embodiment 1, and includes the following steps: S1, initially positioning the leather cup 420 so that the grabbing sleeve 623 is coaxial with the leather cup 420; S2, applying a radial force to the outer circular surface of the leather cup 420 at a first direction so that the leather cup 420 is eccentric to the grabbing sleeve 623 until the corresponding outer circular surface of the leather cup 420 is tangent to the inner cavity wall of the grabbing sleeve 623; S3, applying an axial force to a predetermined position of the end surface of the leather cup 420 away from the grabbing sleeve 623 so that the leather cup 420 is collected into the grabbing sleeve 623 in an elliptical shape; S4, inserting the grabbing sleeve 623 into the valve hole 411 of the valve block 410 until the collection gap 643 is located at the corresponding position of the embedding groove 412; S5, applying a radial force to the inner ring surface of the leather cup 420 at a second direction so that the central axis of the leather cup 420 moves to the side direction close to the central axis of the grabbing sleeve 623; and S6, sequentially applying an axial force to the intermediate position and the predetermined position of the end surface of the leather cup 420 close to the grabbing sleeve 623 so that the leather cup 420 is completely separated from the grabbing sleeve 623 and embedded into the valve hole 411 under the action of the elastic force of the leather cup 420. The predetermined position is specifically the tangent position of the outer circular surface of the leather cup 420 and the inner cavity wall of the grabbing sleeve 623, and the first direction and the second direction are specifically opposite directions along the radial direction of the leather cup 420.

[0075] In step S3, after the axial force is applied to the predetermined position of the side end face of the cup 420 away from the gripping sleeve 623, a guiding force is further applied to the side end face of the cup 420 close to the gripping sleeve 623, so that the outer circumferential surface of the cup 420 on both sides symmetrical about the first direction and the second direction is radially shrunk and deformed.

[0076] As shown in FIGS. 1-15, the embodiment of the present application provides a cup assembly device, which comprises a working frame 100, and a valve block tool, a cup feeding device, a direction recognizing and positioning assembly 800, and a cup pressing assembly installed on the working frame 100.

[0080] The gripping and pressing assembly 620 comprises a gripping sleeve 623 fixedly connected with the driving assembly of the mechanical arm assembly 610, a connecting guide rod 642 is penetratingly and fixedly arranged in the gripping sleeve 623, the connecting guide rod 642 extends to the side of the gripping sleeve 623 close to the working frame 100 and is fixedly arranged with a limiting table 637 close to the working frame 100, and a receiving gap 643 is arranged between the limiting table 637 and the end of the gripping sleeve 623 close to the working frame 100.

[0081] The skin bowl press-fitting assembly further comprises a collection mechanism 500 configured to obliquely press-fit the skin bowl 420 into the grabbing sleeve 623 in an oval shape, a release assembly arranged on the grabbing sleeve 623 and configured to push the skin bowl 420 in the grabbing sleeve 623 out to the collection gap 643, the release assembly comprising a driven crowbar 632 hingedly arranged in the grabbing sleeve 623, the driven crowbar 632 extending to the corresponding position of the collection gap 643 at one end close to the working frame 100 and being fixedly provided with a crowbar head 638.

[0082] The forward skin bowl 420 is specifically the skin bowl 420 with the slotted end 422 facing away from the working frame 100, and is arranged in the grabbing press-fitting assembly 620 for assembling the forward skin bowl 420, the outer cylindrical surface of the grabbing sleeve 623 is gap-fitted with the inner wall of the valve hole 411, the diameter of the limiting table 637 matches the inner ring diameter of the skin bowl 420, and the diameter of the grabbing sleeve 623 is greater than the diameter of the limiting table 637; the reverse skin bowl 420 is specifically the skin bowl 420 with the closed end 421 facing away from the working frame 100, and is arranged in the grabbing press-fitting assembly 620 for assembling the reverse skin bowl 420, the diameter of the grabbing sleeve 623 matches the inner ring diameter of the skin bowl 420, and the diameter of the limiting table 637 is smaller than the diameter of the grabbing sleeve 623.

[0083] In the state that the skin bowl 420 is collected into the grabbing sleeve 623, the part of the skin bowl 420 close to the working frame 100 on the inclined surface relative to the horizontal plane corresponds to the position of the driven crowbar 632, and when the driven crowbar 632 swings relative to the grabbing sleeve 623, the crowbar head 638 can abut against the inner ring surface of the corresponding side of the skin bowl 420 to push the corresponding part of the skin bowl 420 into the embedding groove 412.

[0084] As can be understood, as shown in FIG. 15, the two side end surfaces of the skin bowl 420, one of which is arranged as a flat surface and serves as the closed end 421, and the other of which is arranged as an open slot and serves as the slotted end 422, when the skin bowl press-fitting assembly shapes the skin bowl 420, due to the forward and reverse arrangement of the skin bowl 420 in the valve block 410, in order to avoid the shaping member cutting the skin bowl 420 when shaping the skin bowl 420, it is necessary to perform the shaping action from the closed end 421 side to the slotted end 422 side of the skin bowl 420.

[0085] As can be understood, since the skin bowl 420 needs to be distinguished in terms of front and back during assembly into the valve block 410, the orientation positioning assembly 800 can identify the front and back of the skin bowl 420 at the identification station, and when it is identified that the skin bowl 420 is oriented incorrectly, the skin bowl 420 will be flipped, and when it is identified that the skin bowl 420 is oriented correctly, the assembly of the skin bowl 420 into the valve block 410 will be directly performed.

[0086] When positioning, the skin bowl feeding device outputs the skin bowl 420 to the orientation station of the orientation positioning assembly 800, and the orientation positioning assembly 800 adjusts the skin bowl 420 in the forward and reverse directions, and then the skin bowl pressing assembly collects the skin bowl 420 into the grabbing sleeve 623 through the collection mechanism 500;

[0087] When pressing, the mechanical arm assembly 610 drives the grabbing pressing assembly 620 to move to the position corresponding to the valve block tool, the grabbing sleeve 623 is coaxial with the valve hole 411 of the valve block 410 on the valve block tool, when the grabbing sleeve 623 is positioned, the mechanical arm assembly 610 drives the grabbing sleeve 623 to insert into the valve hole 411, when the collection gap 643 is located at the position corresponding to the embedding groove 412 in the valve hole 411, the driven pry lever 632 swings relative to the grabbing sleeve 623 and pushes the skin bowl 420 into the embedding groove 412 through the pry head 638;

[0088] When shaping, for the forward skin bowl 420, the grabbing pressing assembly 620 moves away from the working frame 100, and the outer circular surface of the limiting table 637 realizes the contact shaping of the inner ring surface of the skin bowl 420; for the reverse skin bowl 420, the grabbing pressing assembly 620 moves close to the working frame 100, and the outer circular surface of the grabbing sleeve 623 realizes the contact shaping of the inner ring surface of the skin bowl 420.

[0089] In the embodiment of the application, the above-mentioned skin bowl assembly equipment is adopted, the feeding state of the skin bowl 420 is identified through the orientation positioning assembly 800, so as to ensure the accuracy of the skin bowl 420 assembly, the skin bowl pressing assembly can automatically grab the skin bowl 420 and perform the pressing of the skin bowl 420 on the valve block 410, and the two groups of skin bowl pressing assemblies respectively perform the assembly of the forward and reverse skin bowls 420, and can directly perform the shaping of the skin bowl 420 after the assembly of the skin bowl 420 is completed, realizing the full-automatic assembly process of the skin bowl 420, which not only reduces the labor cost, but also greatly improves the production efficiency, and at the same time, the diameters of the grabbing sleeves 623 and the limiting tables 637 of the two groups of skin bowl pressing assemblies can ensure that the skin bowl 420 is not damaged in the shaping of the skin bowl 420, further improving the assembly quality of the skin bowl 420.

[0090] As shown in FIGS. 8-13, the edge of the limiting table 637 away from the side surface of the working frame 100 is provided with a chamfer in the grabbing pressing assembly 620 for assembling the forward skin bowl 420;

[0091] The edge of the grabbing sleeve 623 close to the side surface of the working frame 100 is provided with a chamfer in the grabbing pressing assembly 620 for assembling the reverse skin bowl 420.

[0092] It can be understood that the chamfer provided on the grabbing sleeve 623 and the limiting table 637 can guide the leather cup 420 during shaping, thereby ensuring the assembly accuracy of the leather cup 420.

[0093] As shown in FIGS. 8-13, the limiting table 637 is provided with a probe groove 633 axially penetrating through the grabbing sleeve 623, and the grabbing sleeve 623 is provided with a guide groove 634 coaxial with the probe groove 633 at one end close to the working frame 100. The probe groove 633 and the guide groove 634 are located on the opposite side of the pry head 638 with respect to the central axis of the grabbing sleeve 623.

[0094] The collecting mechanism 500 includes a top plate 581 capable of moving axially along the grabbing sleeve 623 and being inserted into the probe groove 633 and the guide groove 634. When the top plate 581 moves away from the working frame 100 and penetrates through the probe groove 633 and the guide groove 634, the leather cup 420 at the collecting gap 643 can be pushed into the grabbing sleeve 623 in an elliptical shape.

[0095] As shown in FIGS. 1 and 2, the leather cup feeding device is specifically provided as a vibrating feeding assembly 200 fixedly arranged on the working frame 100, and the discharging end of the vibrating feeding assembly 200 extends to the orientation work station of the orientation positioning assembly 800.

[0096] It can be understood that the vibrating feeding assembly 200 can transfer the leather cup 420 to the orientation work station of the orientation positioning assembly 800, and the orientation positioning assembly 800 can realize the orientation of the output leather cup 420 of the leather cup feeding device.

[0097] It can be understood that the leather cup feeding device is mainly arranged to transfer the leather cup 420 to the orientation work station of the orientation positioning assembly 800, and the structure form is not limited to the above-mentioned one. For example, a turntable feeding, a belt feeding, a robot feeding, etc. can also be adopted, as long as the feeding action of the leather cup 420 can be realized, which is not specifically limited herein.

[0098] As shown in FIGS. 1 and 2, the leather cup feeding device further includes an oil spraying assembly 900 arranged to spray oil circumferentially on the oriented leather cup 420 and a transfer assembly 700 arranged to transfer the leather cup 420 between the grabbing work station of the leather cup press assembly, the orientation work station of the orientation positioning assembly 800, and the oil spraying work station of the oil spraying assembly 900.

[0099] It can be understood that the reason for spraying oil circumferentially on the leather cup 420 by the oil spraying assembly 900 is that the outer circumferential surface of the leather cup 420 will be in contact with the inner wall of the valve hole 411 during the process of being pressed into the embedding groove 412 by the leather cup press assembly. Under the action of friction, the pose state of the leather cup 420 can be affected. Spraying oil on the circumferential surface of the leather cup 420 can reduce the friction between the leather cup 420 and the inner wall of the valve hole 411, thereby reducing the influence of the friction on the installation accuracy of the leather cup 420.

[0100] As shown in FIGS. 1-3, the orientation positioning assembly 800 includes a mounting seat 820 fixedly arranged on the working frame 100, a telescopic cylinder 821 and a visual sensor 830 fixedly arranged on the mounting seat 820, a placing table 822 fixedly arranged on the telescopic end of the telescopic cylinder 821, and a containing groove capable of containing the rubber bowl 420 output by the rubber bowl feeding device arranged on the placing table 822.

[0101] The orientation positioning assembly 800 further includes a support 810 fixedly arranged on the working frame 100, an electric sliding table 811 capable of moving towards or away from the placing table 822 fixedly arranged on the support 810, a turnover motor 812 fixedly arranged on the electric sliding table 811, and a fork 813 arranged on the output end of the turnover motor 812.

[0102] In the telescopic cylinder 821 retracted state, the containing groove on the placing table 822 corresponds to the output end position of the rubber bowl feeding device, i.e. the rubber bowl 420 output by the rubber bowl feeding device can directly fall into the containing groove on the placing table 822; in the telescopic cylinder 821 extended state, the containing groove on the placing table 822 corresponds to the position of the turnover motor 812.

[0103] Specifically, in the initial state, the telescopic cylinder 821 is in the retracted state, and the electric sliding table 811 is located at the end of the sliding stroke away from the placing table 822; after the rubber bowl 420 output by the rubber bowl feeding device falls into the containing groove on the placing table 822, the visual sensor 830 can perform positive and negative visual detection on the rubber bowl 420 in the containing groove on the placing table 822; if the orientation of the rubber bowl 420 is correct, the rubber bowl 420 is directly transferred to the oil injection station of the oil injection assembly 900 through the transfer assembly 700; if the orientation of the rubber bowl 420 is incorrect, the telescopic cylinder 821 is extended; after the telescopic cylinder 821 is completely extended, the electric sliding table 811 drives the turnover motor 812 and the fork 813 to move towards the placing table 822, the fork 813 performs clamping on the rubber bowl 420 in the containing groove on the placing table 822, the electric sliding table 811 moves away from the placing table 822 to provide adjustment space for the fork 813, the fork 813 turns the rubber bowl 420 by 180° under the drive of the turnover motor 812, the electric sliding table 811 moves towards the placing table 822 after the rubber bowl 420 is turned, and the fork 813 repositions the rubber bowl 420 in the containing groove on the placing table 822, the telescopic cylinder 821 and the electric sliding table 811 are reset, and then the rubber bowl 420 is transferred to the oil injection station of the oil injection assembly 900 through the transfer assembly 700.

[0104] It can be understood that the structure of the orientation positioning assembly 800 is not limited to the above, for example, a clamping and overturning mechanism can be directly arranged at the accommodating groove alignment position on the feeding table 822. On the other hand, the orientation positioning assembly 800 can also be integrally arranged on the rubber cup feeding device, and directly realize the positive and negative orientation during the feeding process of the rubber cup 420.

[0105] It can be understood that the orientation positioning assembly 800 is mainly arranged to identify and adjust the positive and negative directions of the rubber cup 420, but based on the structure of the rubber cup feeding device, when the rubber cup feeding device adopts semi-automatic feeding, that is, the orientation of the rubber cup is adjusted by manual pre-adjustment, the orientation positioning assembly 800 can be correspondingly omitted.

[0106] As shown in FIGS. 1-3, the oil injection assembly 900 includes an oil injection support 910 fixedly arranged on the working frame 100, and an oil injector 920 fixedly arranged on the oil injection support 910.

[0107] It can be understood that the oil injection support 910 is provided with an oil receiving groove at the oil injection position of the oil injector 920, and a sewage discharge pipeline arranged to discharge oil from the oil receiving groove.

[0108] As shown in FIGS. 1, 2 and 4, the transfer assembly 700 includes a support frame 710 fixedly arranged on the working frame 100, a horizontal sliding rail 720 fixedly arranged on the support frame 710, a transfer sliding table 730 slidingly arranged on the horizontal sliding rail 720, a lifting cylinder 740 fixedly arranged on the transfer sliding table 730, a lifting sliding table 750 fixedly arranged on the output end of the lifting cylinder 740, a steering motor 760 fixedly arranged on the lifting sliding table 750, and an inner support grabbing head 770 fixedly arranged on the output end of the steering motor 760.

[0109] It can be understood that the transfer sliding table 730 can move along the length direction of the horizontal sliding rail 720 under the action of an external power device, thereby driving the steering motor 760 and the inner support grabbing head 770 to move synchronously.

[0110] The orientation positioning assembly 800 and the oil injection assembly 900 are located on the moving track of the inner support grabbing head 770. After the orientation positioning assembly 800 finishes the orientation of the cup 420, the transfer sliding table 730 moves to the orientation positioning assembly 800 along the horizontal sliding rail 720, the lifting cylinder 740 extends and grabs the cup 420 at the orientation positioning assembly 800 through the inner support grabbing head 770, then the lifting cylinder 740 retracts to the original position, the transfer sliding table 730 moves to the oil injection assembly 900 along the horizontal sliding rail 720, the lifting cylinder 740 extends to the position corresponding to the oil injector 920, at this time, the oil injector 920 is started, the transfer motor 760 drives the inner support grabbing head 770 to rotate to realize the oil injection on the circumferential surface of the cup 420, after the oil injection of the cup 420 is completed, the transfer sliding table 730 moves to the cup pressing assembly along the horizontal sliding rail 720 and places the cup 420 at the grabbing position of the cup pressing assembly through the lifting cylinder 740, and finally, all components of the transfer assembly 700 are reset to execute the next working cycle.

[0111] It can be understood that the process station setting forms of the orientation positioning assembly 800 and the oil injection assembly 900 are not limited to the above-mentioned one, based on the overall layout of the assembly device, the orientation, oil injection and assembly grabbing of the cup 420 can be set as a nonlinear distribution, so as to improve the compactness of the device, at this time, the transfer assembly 700 needs to increase the horizontal movement degree of freedom of the inner support grabbing head 770, so as to ensure that the inner support grabbing head 770 can transfer the cup 420 between multiple stations, which can be set as replacing the transmission form between the horizontal sliding rail 720 and the transfer sliding table 730 into an X, Y double-shaft sliding table on the horizontal plane, through the driving in two directions on the horizontal plane, the flexible transfer of the inner support grabbing head 770 on the horizontal plane coordinates can be realized, and the overall adaptability of the device is improved.

[0112] As shown in FIG. 1 and FIG. 2, the valve block tooling includes a transposition guide rail 310 fixedly arranged on the working frame 100, and an assembly table 320 is slidably arranged on the transposition guide rail 310. The valve block 410 is installed on the assembly table 320 when the cup 420 is assembled, and the assembly table 320 can slide between the assembly stations of the two sets of cup pressing assembly under the action of an external power device.

[0113] It can be understood that when one set of cup pressing assembly performs forward cup 420 pressing on the valve block 410 at the assembly station, the assembly table 320 at this position is transferred to the assembly station of the other set of cup pressing assembly and performs reverse cup 420 pressing; or when one set of cup pressing assembly performs reverse cup 420 pressing on the valve block 410 at the assembly station, the assembly table 320 at this position is transferred to the assembly station of the other set of cup pressing assembly and performs forward cup 420 pressing.

[0114] The embodiment of the application provides a skin bowl shaping method, which is suitable for the skin bowl assembling device in the above embodiment 3, and comprises the following steps: S1, the skin bowl 420 is oriented in the forward direction and the reverse direction before being assembled, so that the orientation of the skin bowl 420 is matched with the target of the skin bowl press-fitting assembly in the corresponding position; S2, corresponding shaping actions are performed on the skin bowl 420 with different orientations; in the step S2, the following is specifically performed: for the skin bowl 420 with the slotted end 422 oriented away from the ground side, the grabbing sleeve 623 and the limiting table 637 are moved away from the ground side, and the outer circular surface of the limiting table 637 is used to realize the contact shaping of the inner ring surface of the skin bowl 420; for the skin bowl 420 with the closed end 421 oriented away from the ground side, the grabbing sleeve 623 and the limiting table 637 are moved towards the ground side, and the outer circular surface of the grabbing sleeve 623 is used to realize the contact shaping of the inner ring surface of the skin bowl 420.

[0115] In the step S2, the following is further included: when the valve block 410 has a plurality of embedding grooves 412 for installing the forward skin bowl 420, in the direction from the ground to the side of the skin bowl press-fitting assembly, the skin bowl press-fitting assembly sequentially performs the press-fitting and shaping actions of the forward skin bowl 420 on the plurality of embedding grooves 412; when the valve block 410 has a plurality of embedding grooves 412 for installing the reverse skin bowl 420, in the direction from the side of the skin bowl press-fitting assembly to the ground, the skin bowl press-fitting assembly sequentially performs the press-fitting and shaping actions of the reverse skin bowl 420 on the plurality of embedding grooves 412.

[0116] In the step S2, the following is further included: for the skin bowl 420 with the closed end 421 oriented away from the ground side, the grabbing sleeve 623 and the limiting table 637 are moved back and forth along the axial direction of the skin bowl 420 twice, and the outer circular surface of the grabbing sleeve 623 is used to realize the contact shaping of the inner ring surface of the skin bowl 420 twice.

[0117] Before the step S2, the following is further included: after the skin bowl press-fitting assembly moves the skin bowl 420 to the corresponding position of the embedding groove 412, the driven lever 632 is swung and the skin bowl 420 is pushed into the embedding groove 412 by the lever head 638; the grabbing sleeve 623, the driven lever 632 and the limiting table 637 are rotated at least 180° about the central axis of the grabbing sleeve 623.

[0118] It can be understood that the rotation of the grabbing sleeve 623, the driven pry lever 632 and the limiting table 637 is performed on the one hand by pressing the inner ring surface of the leather cup 420 in the circumferential direction by the pry head 638, so that the leather cup 420 is further embedded into the embedding groove 412, and on the other hand, since the grabbing sleeve 623 and the limiting table 637 are provided with the probe groove 633 and the guide groove 634, and the leather cup 420 is only subjected to a one-way force by the pry head 638 during the preliminary pressing, if the leather cup pressing assembly directly performs the shaping action on the leather cup 420, the leather cup pressing assembly is separated from the valve block 410, the leather cup 420 may be deformed and taken out by the leather cup pressing assembly through the probe groove 633 and the guide groove 634, resulting in assembly failure, at this time, the worker still needs to manually handle, greatly affecting the assembly efficiency of the leather cup 420, and when the grabbing sleeve 623, the driven pry lever 632 and the limiting table 637 are rotated more than 180°, the positions of the probe groove 633 and the guide groove 634 are also adjusted synchronously, so that the above problems are avoided.

[0119] After step S2, the driven pry lever 632 and the pry head 638 are rotated back to reset, and the leather cup pressing assembly performs the next work position of the leather cup 420 pressing and shaping cycle.
