Description

Technical Field

[0001] The present application relates to the field of container door panel production, and in particular to an automated production line for container door panels. Background Art

[0002] The existing door panel processing technology for containers usually involves processing the pre-processed door panel through four processes: side trimming, stamping, punching, and tail trimming. The finished door panel is made to meet the required size and shape, and has holes for connecting the door handle.

[0003] Several challenges arise during these four steps. First, when trimming the side and tail edges, the trimming equipment can only trim one side at a time, requiring assistance from a worker to rotate the door panel to trim the two opposing sides. Second, manual handling and positioning are required to transfer door panels between adjacent steps. In addition to the transfer and handling between the four steps, a single door panel also undergoes loading and unloading.

[0004] This means that workers need to move each door panel at least seven times to complete its production. While meeting the production line's production capacity, workers need to adjust the position of the door panel hundreds of times in each process. The production line has a limited degree of automation, which not only leads to higher labor intensity for workers, but also reduces the production efficiency of door panels. Summary of the Invention

[0005] In order to improve the degree of automation of the door panel production line, the present application provides an automated production line for container door panels.

[0006] The present application provides an automated production line for container door panels that employs the following technical solutions:

[0007] An automated production line for container door panels, comprising a stacking device, a trimming device, a stamping device, a punching device, and a trimming device connected in sequence;

[0008] The stacking device is used to stack multiple door panels, a first manipulator is provided between the trimming device and the stacking device, the first manipulator includes a manipulator body and a suction piece installed on the manipulator body, the suction piece is used to suck and place the door panels, the manipulator body is used to drive the door panels to move from the stacking device to the trimming device, a flip piece is provided between the manipulator body and the suction piece, and the flip piece is used to adjust the horizontal layout angle of the door panels;

[0009] A feeding assembly is arranged between the stamping equipment and the trimming equipment, a discharging assembly is arranged between the stamping equipment and the punching equipment, and a second manipulator with the same structure as the first manipulator is arranged between the punching equipment and the trimming equipment. The second manipulator is used to place the door panel on the trimming equipment and adjust the horizontal layout angle of the door panel.

[0010] By adopting the above technical solution, when processing door panels, multiple door panels are stacked and placed by a stacking device, and then the first manipulator drives the adsorption part to adsorb the top door panel and move the door panel to the trimming device. The flip part adjusts the angle of the door panel so that one long side of the door panel is aligned with the trimming device for trimming. Then, the first manipulator flips the door panel horizontally 180 degrees so that the other long side enters the trimming device for trimming. This allows the first manipulator to not only achieve the effect of transporting the door panel, but also to flip the door panel, thereby preliminarily reducing the labor intensity of the workers. The door panel with trimmed long sides enters the stamping device through the feeding assembly for stamping. The stamped door panel enters the punching device for punching through the discharging assembly. The punched door panel is transported to the trimming device by the second manipulator. The second manipulator can also adjust the angle of the door panel so that both short sides of the door panel can be trimmed. This reduces the number of times workers transport and adjust the angle of the door panel. Compared with the prior art, this application improves the degree of automation of the door panel production line and reduces the labor intensity of workers.

[0011] Optionally, the feeding assembly includes a feeding rack, a feeding belt and a guide member;

[0012] The feed belt is installed on the feed rack and is transported horizontally from the edge trimming equipment to the stamping equipment. The feed belt is flush with the feed port of the stamping equipment. The guide member includes two guide plates installed on the feed rack. The guide plates are located above the feed belt and are arranged along the conveying direction of the feed belt. A guide channel for the door panel to slide through is provided between the two guide plates. A guide plate is connected to one end of the guide plate facing the edge trimming equipment, and the guide plate is inclined along the side facing the edge trimming equipment away from the guide channel.

[0013] By employing this technical solution, door panels, after their long edges have been trimmed, are placed on a feed rack and driven by a feed belt toward the inlet of the stamping equipment. Guides define the door panel's position on the feed belt and guide it in its proper position, improving positioning accuracy during stamping. The guide plate also reduces the difficulty of the door panel entering the feed belt, allowing it to enter the stamping equipment for stamping without manual handling.

[0014] Optionally, the discharging assembly includes a discharging rack, a discharging belt, a clamping member and a driving member;

[0015] The discharging belt is installed on the feeding rack and is transported horizontally in the direction from the stamping equipment to the punching equipment. The discharging belt is flush with the discharge port of the stamping equipment. The clamping member is slidably installed on the discharging rack and is used to clamp the short side of the door panel passing through the discharge port of the stamping equipment. A clamping channel for the clamping member to slide is opened in the middle of the discharging belt. The driving member is connected to the clamping member and is used to drive the clamping member to slide horizontally along the transmission direction of the discharging belt.

[0016] By adopting the above technical solution, in order to enable continuous stamping of door panels, a clamping member is installed at the discharge assembly. The door panel section passing through the discharge port of the stamping equipment is placed on the discharge belt, and the side of the door panel at the discharge port of the stamping equipment is clamped by the clamping member. As the driving member drives the clamping member to slide, the stamping position is precisely controlled, and the stamped door panel section is lifted off the stamping equipment. When the door panel is completely stamped, the clamping member releases the door panel, and the door panel is transported to the punching equipment via the discharge belt, thus eliminating the step of manually dragging the door panel.

[0017] Optionally, the clamping member includes a sliding base, a lifting rod, a lifting cylinder and a clamp;

[0018] The discharging rack is provided with a slide rail which is slidably connected to the sliding base along the conveying direction of the discharging belt. The bottom end of the lifting rod is hinged to the sliding base in a vertical plane. The clamp is installed on the top of the lifting rod. The lifting cylinder is located on one side of the lifting rod along its own rotation trajectory and the output shaft is hinged to the lifting rod. The lifting cylinder is hingedly installed on the sliding base.

[0019] By adopting the above technical solution, when clamping the door panel, the lifting cylinder first rotates the lifting rod in the direction away from the stamping equipment, raising the clamp to a position where it can horizontally clamp the door panel. The driving member then drives the sliding base to slide along the layout direction of the slide rail, thereby lifting the door panel away from the clamp. To prevent the clamp from blocking the sliding path of the door panel, the lifting cylinder drives the lifting rod to rotate in the direction toward the stamping equipment, lowering the clamp. This allows the door panel to be moved to the punching equipment via the discharge belt without human handling, thus achieving automated handling.

[0020] Optionally, the clamp includes a clamping main rod, a first clamping rod, a second clamping rod, an opening and closing rod and a clamping cylinder;

[0021] One end of the clamping main rod is vertically connected to the top of the lifting rod and the other end points to the stamping equipment. The first clamping rod is installed at the top of the other end of the clamping main rod, and the second clamping rod is located above the first clamping rod. The bottom of the opening and closing rod is hinged to the first clamping rod and the top is connected to the second clamping rod. The opening and closing rod rotates in the direction of approaching or moving away from the stamping equipment. The clamping cylinder is hingedly installed at the top of the clamping main rod and is located on the side of the second clamping rod away from the stamping equipment. The output shaft of the clamping cylinder is hinged to the second clamping rod.

[0022] By adopting the above technical solution, when the clamp rises until the first clamping rod is flush with the discharge port of the stamping equipment, it stops rising. When the side of the door panel enters between the first clamping rod and the second clamping rod, the clamping cylinder drives the opening and closing rod to rotate in the direction close to the stamping equipment, and the opening rod drives the second clamping rod to rotate in the direction close to the first clamping rod until the second clamping rod and the first clamping rod clamp the door panel, thereby completing the clamping of the door panel.

[0023] Optionally, a lifting member is provided on the discharging rack, and the end of the discharging belt facing away from the stamping equipment is hinged to the discharging rack. The lifting member is located below the discharging belt and close to the side of the stamping equipment. The lifting member is connected to the bottom of the discharging belt and is used to control the flipping and lifting of the discharging belt along the vertical plane.

[0024] By adopting the above technical solution, in order to facilitate the transportation of door panels to the punching equipment through the discharge belt, and at the same time shorten the rotation angle of the lifting rod and improve the transportation efficiency, the lifting part can drive the discharge rack to flip on the vertical plane along the side away from the stamping equipment, and by lifting the discharge rack, the speed of the door panel lifting away from the clamp is accelerated, and at the same time, it is convenient to guide the stamped door panel to quickly slide out of the discharge belt and enter the punching equipment.

[0025] Optionally, the sliding base includes a connecting seat and a sliding seat, the sliding seat is in sliding contact with the slide rail and an upper end surface of the sliding seat is provided with a buffer groove for the connecting seat to slide along the layout direction of the slide rail;

[0026] A buffer spring is connected between the connecting seat and the sliding seat. The buffer spring is located on the side of the connecting seat facing the stamping equipment and is arranged along the sliding direction of the sliding seat. A locking assembly is connected between the connecting seat and the sliding seat. The locking assembly is used to lock the position of the connecting seat when the sliding seat slides and unlock the position of the connecting seat when the sliding seat is stationary.

[0027] By adopting the above technical solution, when the stamping equipment is performing stamping, one end of the door panel is fixed on the clamp and the other end is in an active state. The impact force and stress received during stamping are likely to cause the free end panel section of the door panel to deform or deflect due to uneven force, resulting in inaccurate size of the door panel after stamping.

[0028] In order to improve this phenomenon, when the sliding seat is in a sliding state, the locking assembly drives the connecting seat and the door panel to move together. When the sliding seat stops, the stamping equipment stamps the door panel. At this time, the locking assembly unlocks the position of the connecting seat. When the stamping equipment stamps the door panel, the sliding seat can slide in the direction close to the stamping equipment due to the tension generated by the deformation of the door panel, so that the two ends of the door panel section of the stamping part are evenly stressed, so as to improve the situation where the door panel is deformed or skewed during stamping.

[0029] Optionally, the locking assembly includes a locking slider, a locking slide rod, an elastic member, a locking gear, a locking member and an unlocking member;

[0030] The bottom of the buffer slide is provided with a locking slide hole for the vertical sliding of the locking slider, the bottom end of the connecting seat is provided with a locking socket for the locking slider to be inserted, the locking slide rod is vertically slidably connected to the sliding seat and connected to the locking slider, the elastic member is connected to the locking slide rod, the middle section of the side wall of the locking slide rod is provided with a vertically arranged locking rack, the locking gear is rotatably mounted on the sliding seat and meshes with the locking rack, and the locking gear is connected with a locking member and an unlocking member;

[0031] When the sliding seat moves, the locking member drives the locking gear to rotate counterclockwise until the locking gear is located below the locking rack, and the locking slider is inserted into the locking socket;

[0032] When the sliding member stops, the unlocking member drives the locking gear to rotate clockwise until the locking gear is located above the locking rack, and the locking slider is inserted into the locking socket;

[0033] When the locking gear is located above the locking rack, the elastic member is used to control the locking slide bar to abut against the locking gear downward; when the locking gear is located above the locking rack, the elastic member is used to control the locking slide bar to abut against the locking gear upward.

[0034] By adopting the above technical solution, when the sliding seat moves away from the stamping equipment, the locking member drives the locking gear to rotate counterclockwise, causing the locking slide and locking slider to slide upward, and the locking slider to insert into the locking socket. When the sliding member stops, the unlocking member can drive the locking gear to rotate clockwise, causing the locking slider to slide out of the locking socket. Because the locking rack is mounted in the middle of the unlocking slide, the length of the locking rack determines the lifting distance of the locking slider. Moreover, when the locking gear rotates above or below the locking rack, the continued rotation of the locking gear keeps the locking rack position constant, thereby achieving continuous locking and unlocking. The elastic member ensures that the locking rack is always in contact with the locking gear. Once the locking gear turns, the locking rack can be meshed with the locking gear in a timely manner to change the position of the locking slider.

[0035] Optionally, the locking member includes a driving rack, a driving gear and a locking ratchet;

[0036] The driving rack is installed on the top of the slide rail along the layout direction of the slide rail, the driving gear is rotatably installed on the sliding seat and meshes with the driving rack, the locking gear is coaxially connected with a linkage rod, the locking ratchet is rotatably sleeved on the linkage rod, the driving gear is coaxially provided with a locking tooth groove meshing with the locking ratchet, the locking ratchet is abutted against a baffle on the side facing away from the stamping equipment, and a compression spring is connected between the linkage rod and the locking ratchet to drive the locking ratchet to press against the baffle.

[0037] By adopting the above technical solution, when the sliding seat moves in the direction away from the stamping equipment, the driving gear rotates counterclockwise and drives the rack to engage the transmission, and the locking ratchet presses against the baffle to drive the combining rod and the locking gear to rotate counterclockwise, so that the locking slider can be inserted into the locking socket. After that, the locking gear continues to rotate and the position of the locking slider remains stable.

[0038] Optionally, the unlocking member includes an unlocking shaft and an unlocking coil spring;

[0039] The unlocking shaft is installed on the sliding seat and is coaxially connected to the locking gear. The locking gear is coaxially provided with an unlocking cavity for placing an unlocking spring. The inner end of the unlocking spring is fixed to the unlocking shaft and the outer end is connected to the wall of the unlocking cavity.

[0040] By adopting the above technical solution, when the locking gear rotates counterclockwise, the coil spring deforms. When the sliding seat stops sliding, the coil spring drives the locking gear to rotate clockwise. At this time, the combined rod and the locking ratchet also rotate clockwise. The locking ratchet moves away from the stop rod, thus preventing the driving gear from rotating. Until the coil spring resets, the locking slider slides away from the locking socket.

[0041] In summary, this application includes at least one of the following beneficial technical effects:

[0042] 1. The first manipulator and the second manipulator can realize the effect of door panel conversion equipment and adjusting its own layout position. Since the stamping equipment accounts for a relatively large proportion of manual labor, the feeding equipment and the discharging equipment can realize the effect of automatic stamping and feeding and discharging of workpieces, thereby solving the problem of manual labor requiring multiple handling of door panels and adjustment of door panel angles, reducing workers' labor intensity and improving the degree of automation of the door panel production line;

[0043] 2. To enable continuous stamping of the door panel, the clamping parts clamp the side of the door panel at the discharge port of the stamping equipment. As the driving part drives the clamping parts to slide, the stamping position is precisely controlled. When the door panel is completely stamped, the clamping parts release the door panel and the door panel is transported to the punching equipment via the discharge belt, thus saving the step of manually dragging the door panel;

[0044] 3. When the stamping equipment stamps the door panel, the locking assembly unlocks the position of the connecting seat, and the sliding seat can slide in the direction close to the stamping equipment due to the tension generated by the deformation of the door panel, so that the two ends of the door panel section of the stamping part are evenly stressed, so as to improve the deformation or deflection of the door panel during stamping.

DETAILED DESCRIPTION

[0055] The following is combined with Figure 1-9 This application is described in further detail.

[0056] Example 1

[0057] The embodiment of the present application discloses an automated production line for container door panels. Figure 1 and Figure 2 The production line includes a stacking device 1, a trimming device 3, a stamping device 4, a punching device 5, and a trimming device 7 which are connected in sequence according to the production process.

[0058] Among them, multiple door panels are placed on the stacking equipment 1, and the stacking equipment 1 stacks the multiple door panels vertically. A first manipulator 2 is connected between the trimming device 3 and the stacking equipment 1. The first manipulator 2 includes a manipulator body 21 and a suction member 22 installed on the manipulator body 21. The suction member 22 can absorb and place the door panels. The manipulator body 21 can drive the door panels from the stacking equipment 1 to the trimming device 3 through the suction member 22. Since the door panels have two long sides and two short sides arranged relative to each other, a flip member 23 is installed between the manipulator body 21 and the suction member 22. The flip member 23 can adjust the horizontal arrangement angle of the door panels. After the trimming device 3 trims one of the long sides of the door panel, the flip member 23 can drive the door panel to rotate 180 degrees in the horizontal plane to facilitate the trimming device 3 to trim the other long side of the door panel, thereby saving the steps of manual handling and adjusting the position of the door panel.

[0059] Furthermore, a feeding assembly 8 is provided between the stamping device 4 and the trimming device 3, and a discharging assembly 9 is provided between the stamping device 4 and the punching device 5, thereby saving the step of manually adjusting the position of the door panel during stamping.

[0060] In addition, a second manipulator 6 with the same structure as the first manipulator 2 is arranged between the punching device 5 and the trimming device 7. The second manipulator 6 is used to place the door panel on the trimming device 7 and adjust the horizontal layout angle of the door panel to facilitate trimming the two short sides of the door panel, thereby saving the steps of manual handling of the door panel as a whole, reducing the labor intensity of workers, and improving the degree of automation of the door panel production line.

[0061] When stamping door panels, the highest level of manual intervention is required. Not only does the door panel need to be kept horizontal before entering the stamping equipment 4, but the relative position of the door panel segment and the stamping equipment 4 needs to be adjusted according to the stamping position. Each time a door panel segment is stamped, the door panel position needs to be adjusted in time to facilitate continuous stamping. In the stamping process, if there is a problem with the stamping position or shape of a door panel segment, the door panel needs to be reselected for stamping. Therefore, the stamping process of door panels is the most complicated and requires the highest concentration and position accuracy of the workers. Improving the degree of automation of this part of the stamping equipment 4 is also the most important.

[0062] Reference Figure 2 and Figure 3The feeding assembly 8 includes a feeding rack 81, a feeding belt 82 and a guide member 83.

[0063] The feed belt 82 is mounted on the feed rack 81 and conveys horizontally from the trimming device 3 to the stamping device 4. The feed belt 82 is flush with the feed inlet of the stamping device 4. The guide member 83 includes two guide plates 831 mounted on the feed rack 81. The guide plates 831 are located above the feed belt 82 and arranged along the conveying direction of the feed belt 82. A guide channel 832 is provided between the two guide plates 831 for the door panel to slide through.

[0064] As the door panel is conveyed on the feed belt 82, it is positioned between two guide plates 831. These two guide plates 831 prevent the door panel from falling and allow for adjustment of the panel's angle of placement, ensuring that its long edge lies parallel to the conveyance direction of the feed belt 82. This improves positioning accuracy during stamping. A guide plate 833 is connected to the end of the guide plate 831 facing the edge trimming device 3. The side of the guide plate 833 facing the edge trimming device 3 is tilted away from the guide channel 832 to increase the area within which the door panel enters the guide channel 832.

[0065] Reference Figure 3 and Figure 4 The discharging assembly 9 includes a discharging frame 91 , a discharging belt 92 , a clamping member 93 and a driving member 94 .

[0066] The discharge belt 92 is mounted on the feed frame 81 and conveys horizontally from the stamping device 4 to the punching device 5. The discharge belt 92 is flush with the discharge port of the stamping device 4. The clamping member 93 is slidably mounted on the discharge frame 91 and clamps the door panel through the short side of the discharge port of the stamping device 4. A clamping channel is provided in the middle of the discharge belt 92 for the clamping member 93 to slide. When the door panel moves to the discharge port of the stamping device 4, the lower end surface of the door panel abuts the discharge belt 92 to support the door panel. The driving member 94 is connected to the clamping member 93 to facilitate driving the clamping member 93 to slide horizontally along the conveying direction of the discharge belt 92, thereby adjusting the stamping position of the door panel and improving the stamping accuracy of the door panel.

[0067] The driving member 94 may be a cylinder, a linear motor or a belt. Any device that can drive the clamping member 93 to slide horizontally may be used as the driving member 94 .

[0068] Then, the clamping member 93 includes a sliding base 931, a lifting rod 932, a lifting cylinder 933 and a clamp.

[0069] The discharge rack 91 is mounted with a slide rail that is slidably connected to the sliding base 931 along the conveying direction of the discharge belt 92. The bottom end of the lifting rod 932 is vertically hinged to the sliding base 931, and the clamp is mounted on the top of the lifting rod 932. The lifting cylinder 933 is located on the side of the lifting rod 932 along its own rotation trajectory, and its output shaft is hinged to the lifting rod 932. The lifting cylinder 933 is hingedly mounted on the sliding base 931 and is located on the side of the lifting cylinder 933 facing the stamping equipment 4.

[0070] When the output shaft of the lifting cylinder 933 is extended, the lifting rod 932 rotates counterclockwise, thereby driving the clamp to rise. When the clamp is not in use, the output shaft of the lifting rod 932 is shortened, and the lifting rod 932 moves the clamp down to below the discharge belt 92, so that the discharge belt 92 can drive the punched door panel to the punching device 5.

[0071] In addition, the clamp includes a clamping main rod 934 , a first clamping rod 935 , a second clamping rod 936 , an opening and closing rod 937 and a clamping cylinder 938 .

[0072] One end of the clamping main rod 934 is vertically connected to the top of the lifting rod 932, and the other end points toward the stamping equipment 4. The first clamping rod 935 is installed on the top of the other end of the clamping main rod 934, and the second clamping rod 936 is located above the first clamping rod 935. The opening and closing rod 937 is hinged at the bottom to the first clamping rod 935 and connected at the top to the second clamping rod 936. The opening and closing rod 937 rotates in the direction of approaching or moving away from the stamping equipment 4. The clamping cylinder 938 is hingedly installed at the top of the clamping main rod 934 and is located on the side of the second clamping rod 936 away from the stamping equipment 4. The output shaft of the clamping cylinder 938 is hinged to the second clamping rod 936.

[0073] When clamping a door panel, the lifting rod 932 first drives the clamp upward until the first clamping rod 935 is flush with the discharge port of the punching device 4, so that the door panel can slide horizontally into the gap between the first clamping rod 935 and the second clamping rod 936. Then, the clamping cylinder 938 drives the opening and closing rod 937 to rotate in the direction closer to the punching device 4 until the second clamping rod 936 and the first clamping rod 935 clamp the door panel.

[0074] In addition, a lifting member 95 is provided on the discharge rack 91. The end of the discharge belt 92 facing away from the stamping device 4 is hinged to the discharge rack 91. The lifting member 95 is located below the discharge belt 92 and close to the stamping device 4. The lifting member 95 is connected to the bottom of the discharge belt 92 and controls the discharge belt 92 to tilt and rise along the vertical plane. In this embodiment, the lifting member 95 is preferably a cylinder.

[0075] When the door panel is stamped, the clamp 93 completely drags the door panel onto the discharge belt 92, and the clamp releases the door panel. The lifting cylinder 933 drives the clamp downward, and then the lifting member 95 drives the discharge belt 92 to flip on the vertical plane along the side away from the stamping device 4, while shortening the rotation angle of the lifting rod 932 to improve conveying efficiency. By lifting the discharge rack 91, the speed at which the door panel is lifted off the clamp is accelerated, and at the same time, the stamped door panel is guided to slide quickly off the discharge belt 92 and enter the punching device 5.

[0076] The implementation principle of an automated production line for container door panels in Example 1 of the present application is as follows: when producing door panels, multiple door panels are first stacked together by a stacking device 1 for subsequent handling, the first manipulator 2 transfers the door panels to the trimming device 3, trims the two side edges of the door panels along the length direction, and then drives the door panels into the stamping device 4 for stamping through the feeding assembly 8, clamps one of the short sides of the door panels by the clamping member 93 and pulls the door panels according to the stamping position to adjust the stamping position accuracy of the door panels until all the door panels are located on the discharge belt 92, then the clamp descends, and the discharge belt 92 flips to drive the stamped door panels into the punching device 5 for punching, and the door panels after punching are grabbed by the second manipulator 6 and driven to the trimming device 7, trimming the two side edges of the door panels along the width direction, thereby completing the entire processing of the door panels. During the processing, the staff did not manually carry or adjust the door panels, thereby reducing the labor intensity of the staff and improving the degree of automation of the door panel production line.

[0077] Example 2

[0078] The difference between the second embodiment of the present application and the first embodiment is that: when the stamping device 4 is stamping, one end of the door panel is fixed on the clamp and the other end is in an active state. The impact force and stress received during the stamping are likely to cause the free end panel segment to deform or deflect due to uneven force, resulting in inaccurate size of the door panel after stamping. In order to improve this phenomenon, reference is made to Figure 5 and Figure 6 The sliding base 931 includes a connecting base 9311 and a sliding base 9312 .

[0079] The sliding seat 9312 slides against the slide rail and has a buffer groove 9313 on its upper end surface, allowing the connecting seat 9311 to slide along the slide rail's orientation. A buffer spring 9314 is connected between the connecting seat 9311 and the sliding seat 9312. The buffer spring 9314 is located on the side of the connecting seat 9311 facing the punching device 4 and is arranged along the sliding direction of the sliding seat 9312. A locking assembly 10 is connected between the connecting seat 9311 and the sliding seat 9312.

[0080] When the sliding seat 9312 is in a stationary state, the locking assembly 10 unlocks the position of the connecting seat 9311. At this time, when the stamping device 4 stamps the door panel, the stamped door panel section can drive the connecting seat 9311 to move in the direction close to the stamping device 4 when deformed. The buffer spring 9314 contracts, so that the two ends of the stamped door panel section are evenly stressed, thereby improving the situation where the door panel is deformed or deflected during stamping. When the sliding seat 9312 needs to slide, the buffer spring 9314 extends and drives the connecting seat 9311 to reset. The locking assembly 10 locks the position of the connecting seat 9311, so that the sliding seat 9312 can drive the connecting seat 9311 to slide together.

[0081] like Figure 6 and Figure 7 As shown, the locking assembly 10 includes a locking slider 101 , a locking slide bar 102 , an elastic member 103 , a locking gear 104 , a locking member 105 and an unlocking member 106 .

[0082] The bottom of the buffer chute 9313 is provided with a locking slide hole for the vertical sliding of the locking slider 101, and the bottom of the connecting seat 9311 is provided with a locking socket for the insertion of the locking slider 101. The locking slide bar 102 is vertically slidably connected to the sliding seat 9312 and is connected to the locking slider 101. The elastic member 103 is connected to the locking slide bar 102. A vertically arranged locking rack 107 is provided in the middle section of the side wall of the locking slide bar 102 facing away from the stamping device 4. The locking gear 104 is located on the side of the locking slide bar 102 facing away from the stamping device 4 and is rotatably mounted on the sliding seat 9312. The locking gear 104 meshes with the locking rack 107 on the locking slide bar 102.

[0083] When the sliding seat 9312 is in a stationary state, the locking gear 104 is located above the locking rack 107 on the locking slide bar 102, the locking slider 101 is located in the locking slide hole, and the locking gear 104 is abutted against the uppermost tooth groove of the locking rack 107 by the elastic member 103, so that the locking gear 104 can be meshed with the locking rack 107 at any time. In this embodiment, the elastic member 103 is preferably a spring to provide space for the lifting and lowering of the locking slide bar 102.

[0084] In addition, refer to Figure 5 and Figure 8 The locking member 105 includes a driving rack 1051 , a driving gear 1052 and a locking ratchet 1053 .

[0085] The driving rack 1051 is installed on the top of the slide rail along the layout direction of the slide rail, the driving gear 1052 is rotatably installed on the sliding seat 9312 and meshes with the driving rack 1051, and the locking gear 104 is coaxially connected to the linkage rod 108. Figure 9As shown, the locking ratchet 1053 is rotatably sleeved on the linkage rod 108, and the driving gear 1052 is coaxially provided with a locking tooth groove that meshes with the locking ratchet 1053. The locking ratchet 1053 is abutted against a baffle 1054 on the side facing away from the stamping equipment 4, and a compression spring 1055 is connected between the linkage rod 108 and the locking ratchet 1053 to drive the locking ratchet 1053 to press against the baffle 1054.

[0086] When the sliding seat 9312 starts to slide, as the driving member 94 drives the sliding seat 9312 to slide, the driving rack 1051 and the driving gear 1052 engage, thereby driving the driving rack 1051 to rotate counterclockwise. The locking ratchet 1053 is connected to the locking tooth groove, so that the linkage rod 108 drives the locking gear 104 to rotate counterclockwise. The locking rack 107 drives the locking slide 102 to rise, and the locking slide 101 is inserted into the locking socket until the locking rack 107 is above the locking gear 104. After that, the locking gear 104 continues to rotate, and the locking rack 107 maintains its position.

[0087] In addition, if Figure 8 As shown, the unlocking member 106 includes an unlocking shaft 1061 and an unlocking coil spring 1062 .

[0088] The unlocking shaft 1061 is installed on the sliding seat 9312 and is coaxially connected to the locking gear 104. The locking gear 104 is coaxially provided with an unlocking cavity for placing the unlocking spring 1062. The inner end of the unlocking spring 1062 is fixed to the unlocking shaft 1061 and the outer end is connected to the wall of the unlocking cavity.

[0089] When the sliding seat 9312 begins to slide, the locking gear 104 rotates counterclockwise, the unlocking spring 1062 begins to deform, and the spacing between adjacent coils increases. When the sliding seat 9312 stops sliding, the unlocking spring resets, driving the locking gear 104 to rotate clockwise. The locking rack 107 drives the locking slide bar 102 and the locking slider 101 downward until the locking rack 107 is located below the locking gear 104. The elastic member 103 can drive the locking rack 107 to always abut the locking gear 104, so that it can mesh with the locking gear 104 in time when the locking gear 104 changes its rotation direction.

[0090] During the clockwise rotation of the locking gear 104, the connecting rod rotates together with the locking gear 104, and the locking ratchet 1053 presses against the compression spring 1055 so that the locking ratchet 1053 disengages from the locking tooth groove and rotates, so that the locking slider 101 slides downward to disengage from the locking socket, and the connecting seat 9311 can slide relative to the sliding seat 9312.

[0091] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
