[0002] A speaker is a transducer that converts electrical signals into sound signals. The performance of the speaker has a great impact on the sound quality. The speaker is the weakest component in the audio equipment, but it is also the most important component for the sound effect.

[0003] The magnetic circuit of the speaker is composed of a magnetic bowl, a magnetic plate and a pole piece, which are stacked in sequence and connected by gluing. In the related art, the assembly of the speaker magnetic circuit is performed by manual dispensing with auxiliary tooling. Due to the small size of the three parts and the small positioning structure on the auxiliary tooling, the production efficiency and the positioning accuracy between the parts of the product will be negatively affected during mass production. Summary of the invention

[0004] In order to improve the above problems, the present application provides a fully automatic loudspeaker magnetic circuit production line.

[0006] By adopting the above technical solution, the pole pieces, magnetic sheets and magnetic bowls are automatically placed on the tooling blocks in sequence. The dispensing mechanism adds glue and then pressurizes and heat-bakes it for reinforcement. The assembled workpiece on the tooling block is then removed by the unloading assembly. The empty tooling blocks can be used for part-bearing assembly again. The production line works continuously, which improves production efficiency.

[0007] Preferably, the feeding mechanism includes a first centrifugal disk, a second centrifugal disk and a third centrifugal disk arranged in sequence along the moving direction of the tooling block, the first centrifugal disk is used to send the pole piece to the circulation slide, the second centrifugal disk is used to send the magnetic piece to the circulation slide, and the third centrifugal disk is used to send the magnetic bowl to the circulation slide, and a transfer component for moving the pole piece, the magnetic piece or the magnetic bowl to the tooling block is provided between the frame and the first centrifugal disk, the second centrifugal disk and the third centrifugal disk, and the transfer component includes a transfer block, which is movably connected to the frame, and the transfer block adsorbs the pole piece, the magnetic piece or the magnetic bowl through a negative pressure airflow; the glue dispensing mechanism includes a glue injection needle, and the glue injection needle is provided with two groups, and the two groups of glue injection needles are respectively located between the first centrifugal disk and the second centrifugal disk, and between the second centrifugal disk and the third centrifugal disk.

[0008] By adopting the above technical solution, after the transfer component places the pole pieces and magnetic pieces respectively delivered by the first and second centrifugal disks on the tooling block, the glue dispensing mechanism adds glue on top of the pole pieces and magnetic pieces. When the magnetic pieces and magnetic bowls are placed, they naturally contact with the glue to achieve bonding of the parts.

[0009] Preferably, the transfer assembly includes an offset slide, which is slidably connected to the frame, and the sliding direction is parallel to the moving direction of the tooling block. A positioning groove is provided on the offset slide. During the movement of the offset slide, the positioning groove and the end of the first centrifugal disk are intermittently connected. When the positioning groove and the end of the first centrifugal disk are connected, the positioning groove allows a single pole piece to slide into.

[0010] By adopting the above technical solution, when the seating groove and the end of the first centrifugal disk are connected, a single seating groove is provided for a pole piece or a magnetic piece to slide into, and then the offset slide moves, and the pole piece or the magnetic piece at the end of the centrifugal disk abuts against the side wall of the offset slide and cannot move forward, thereby reducing the stacking caused by the accumulation of pole pieces, magnetic pieces or magnetic bowls here.

[0011] Preferably, a positioning groove is provided on the side wall of the tooling block, and a positioning slider is slidably arranged on the frame, and the sliding direction is perpendicular to the moving direction of the tooling block. When the movable block adsorbs and transports the pole piece, magnetic piece or magnetic bowl, the positioning slider is inserted into the positioning groove.

[0012] By adopting the above technical solution, when the transfer assembly takes and places the pole piece, magnetic piece or magnetic bowl, the end of the positioning slider is inserted into the corresponding positioning groove and abuts the tooling block to position the tooling block, thereby improving the position stability of the tooling block and further improving the placement accuracy of the parts.

[0013] Preferably, the glue dispensing mechanism also includes a glue injection rack and a cleaning assembly, the cleaning assembly includes a cleaning box and a cleaning sponge, the cleaning box is connected to the frame, the cleaning sponge is located in the cleaning box, and the glue injection rack is used to control the movement of the glue injection needle relative to the frame and allow the needle tip of the glue injection needle to be inserted into the cleaning sponge.

[0014] By adopting the above technical solution, with long-term use, the needle of the glue injection needle will have residual solidified glue. It can be set that after every certain number of dispensing cycles, the glue injection frame controls the needle of the glue injection needle to insert into the cleaning box and rub the needle and the cleaning sponge to remove the solidified glue on the needle.

[0015] Preferably, a rejection mechanism is also provided on the frame next to the circulating slide, and the rejection mechanism includes a detection sensor and a material return assembly, the detection sensor is used to detect the placement of parts on the tooling block, and the material return assembly is used to selectively reject the parts on the tooling block.

[0016] By adopting the above technical solution, the detection sensor is used to detect the placement of parts on the tooling block. If it is detected that the parts are not placed correctly or there is a problem with the assembly of the parts, the detection sensor will control the return component to remove the corresponding parts here to ensure the production yield.

[0017] Preferably, a top piece hole is vertically opened on the upper edge of the circulating slide, and a clearance hole is vertically opened on the upper edge of the tooling block, and the upper port of the clearance hole is blocked when the pole piece is placed on the tooling block; the material return assembly includes a lifting cylinder and a horizontal pushing cylinder, and the lifting cylinder and the horizontal pushing cylinder are fixedly connected to the frame, the lifting cylinder is located below the circulating slide and the piston rod and the top piece hole are coaxial, the extension and retraction direction of the piston rod of the horizontal pushing cylinder is perpendicular to the length direction of the circulating slide, the piston rod of the lifting cylinder abuts against the lower side of the pole piece, and the piston rod of the horizontal pushing cylinder hits the side edge of the magnetic bowl.

[0018] By adopting the above technical solution, after the lifting cylinder extends the piston rod, the end of the piston rod passes through the top piece hole and the give way hole, the piston rod of the lifting cylinder abuts against the lower side of the pole piece and lifts it to the height of the piston rod of the horizontal push cylinder, and then the piston rod of the horizontal push cylinder extends out and hits the side edge of the magnetic bowl. After the parts are subjected to the lateral thrust, they fly out in the horizontal direction to achieve material removal.

[0019] Preferably, an auxiliary block is hingedly provided at the end of the piston rod of the jacking cylinder, the hinge axis is parallel to the length direction of the circulating slide, and the hinge axis is located on the side of the piston rod of the jacking cylinder away from the horizontal thrust cylinder, and a torsion spring is provided on the hinge axis between the auxiliary block and the piston rod of the jacking cylinder. In a natural state, the top surface of the auxiliary block is parallel to the upper surface of the tooling block.

[0020] Preferably, an auxiliary plate is slidingly provided on the top of the auxiliary block, and the plate surface of the auxiliary plate facing away from the auxiliary block is in contact with the magnetic sheet, an initial position spring is connected between the auxiliary plate and the auxiliary block, and in a natural state, the sliding direction of the auxiliary plate relative to the auxiliary block is parallel to the extension and retraction direction of the piston rod of the lifting cylinder, and an auxiliary pull rope is connected between the auxiliary plate and the piston rod of the lifting cylinder.

[0021] By adopting the above technical solution, when rejecting, the end of the piston rod of the horizontal push cylinder abuts against the edge of the magnetic bowl and the side wall of the auxiliary block. After the auxiliary block is subjected to the horizontal thrust, it swings toward the side of the scrap trough; at the same time, since the distance between the connection point between the auxiliary plate and the auxiliary pull rope relative to the piston rod end of the jacking cylinder becomes longer, the auxiliary pull rope has a tendency to lengthen, and the auxiliary plate moves closer to the auxiliary block under the tension, so that the parts on the auxiliary plate are easier to detach from the auxiliary plate, thereby improving the success rate of rejection; and since the piston rod of the horizontal push cylinder will inevitably collide with the auxiliary block, the accuracy requirement of its installation position is greatly reduced.

[0022] In summary, the present application includes at least one of the following beneficial technical effects: 1. Through the setting of the conveying device, circulating slideway, feeding mechanism, dispensing mechanism, hot drying channel and unloading assembly, the pole piece, magnetic piece and magnetic bowl are automatically placed on the tooling block in sequence. The dispensing mechanism adds glue and then pressurizes and heats the workpiece for reinforcement. Then the unloading assembly removes the assembled workpiece on the tooling block. The vacant tooling block can be used for part bearing assembly again. The production line works continuously, which improves production efficiency. 2. Through the setting of the rejection mechanism, the detection sensor detects the workpiece on the tooling block that has been processed in the previous process. When assembly quality defects or placement position deviations are detected, the material removal component ejects the parts on the tooling block to prevent the parts from being subsequently processed, thereby improving the yield rate.

DETAILED DESCRIPTION

[0030] The following is combined with Figure 1-6 This application is described in further detail.

[0031] Embodiment 1: The present application embodiment discloses a fully automatic loudspeaker magnetic circuit production line, such as Figure 1 and 2 As shown, it includes a frame 1 and a conveying device 5. A circulating slide 11 is provided on the frame 1. A plurality of tooling blocks 13 are placed on the frame 1 and on the circulating slide 11. The conveying device 5 is used to drive the tooling blocks 13 to move in a directional and cyclic manner along the circulating slide 11. The tooling blocks 13 are used to place three parts of the loudspeaker magnetic circuit 7: a pole piece 71, a magnetic piece 72 and a magnetic bowl 73. The frame 1 is also provided with a feeding mechanism 2, a glue dispensing mechanism 3, a hot drying channel 17 and a discharge assembly 4. The feeding mechanism 2 is used to place the pole piece 71, the magnetic piece 72 and the magnetic bowl 73 on the tooling block 13 from bottom to top in sequence. The glue dispensing mechanism 3 is used to add glue between the magnetic bowl 73 and the magnetic piece 72, and between the magnetic piece 72 and the pole piece 71. The hot drying channel 17 is used to perform hot drying treatment on the parts on the tooling block 13 that have passed through the glue dispensing mechanism 3. The discharge assembly 4 is used to remove the parts on the tooling block 13 that have passed through the hot drying channel 17 from the tooling block 13.

[0032] like Figure 1 and 2As shown, the track of the circulating slide 11 is rectangular, and the tooling block 13 is approximately rectangular. When placed on the circulating slide 11, its upper surface is provided with two positions for placing the speaker magnetic circuit 7. The pole piece 71 and the magnetic sheet 72 are both rectangular thin sheets, and the magnetic bowl 73 is a rectangular metal sheet with a bent structure on the edge. Above the tooling block 13, the bending direction of the bent structure on the edge of the magnetic bowl 73 is downward.

[0033] like Figure 1 As shown, the feeding mechanism 2 includes a first centrifugal disc 21, a second centrifugal disc 22 and a third centrifugal disc 23 which are arranged in sequence along the moving direction of the tooling block 13. The first centrifugal disc 21 is used to send the pole piece 71 to the circulating slide 11, the second centrifugal disc 22 is used to send the magnetic piece 72 to the circulating slide 11, and the third centrifugal disc 23 is used to send the magnetic bowl 73 to the circulating slide 11. A transfer component 24 for moving the pole piece 71, the magnetic piece 72 or the magnetic bowl 73 to the tooling block 13 is provided between the frame 1 and the first centrifugal disc 21, the second centrifugal disc 22 and the third centrifugal disc 23. At the feeding mechanism 2, the arrangement direction of the two positions for placing parts on the tooling block 13 is consistent with the moving direction of the tooling block 13, and the conveying device 5 drives the tooling block 13 to move one position at a time. The first centrifugal disc 21, the second centrifugal disc 22 and the third centrifugal disc 23 each have two parallel material chutes, that is, the transfer component 24 transports two pole pieces 71, magnetic pieces 72 or magnetic bowls 73 to the tooling block 13 at a time. The three centrifugal discs are arranged in parallel, and their material chutes are parallel to each other, and the length direction is perpendicular to the length direction of the circulation chute 11 here.

[0034] like Figure 1 and 3As shown, the transfer assembly 24 includes a transfer block 241 and a dislocation slide 242. The transfer block 241 is slidably connected to the frame 1. A cylinder is fixedly arranged on the frame 1 to control the two-dimensional movement of the transfer block 241 along the length direction perpendicular to the circulation slide 11 there. The transfer block 241 is provided with a negative pressure airway and is externally connected to a negative pressure pump. The transfer block 241 grasps and moves by negative pressure adsorption of the pole piece 71, the magnetic piece 72 or the magnetic bowl 73. The dislocation slide 242 is located at the end of the material slide of the first centrifugal disc 21, the second centrifugal disc 22 or the third centrifugal disc 23 and is slidably connected to the frame 1. The sliding direction is parallel to the moving direction of the tooling block 13. Two positioning grooves 243 are provided on the dislocation slide 242. Taking the offset slide 242 between the first centrifugal disk 21 and the frame 1 as an example, during the movement of the offset slide 242, its positioning groove 243 is intermittently connected to the end of the first centrifugal disk 21. When the positioning groove 243 is connected to the end of the first centrifugal disk 21, a single positioning groove 243 is provided for one pole piece 71 to slide into; then the offset slide 242 moves, and the pole piece 71 at the end of the first centrifugal disk 21 abuts against the side wall of the offset slide 242 and cannot move forward, thereby reducing the stacking caused by the accumulation of the pole pieces 71 here. At the same time, the pole piece 71 on the moved offset slide 242 is located directly below the transfer block 241 waiting to be sucked.

[0035] like Figure 2 and 3 As shown, a positioning groove 131 is provided on the side wall of the tooling block 13, and a positioning slider 14 is slidably provided on the frame 1, and the sliding direction is perpendicular to the moving direction of the tooling block 13. A positioning cylinder for pushing and pulling the positioning slider 14 is also provided on the frame 1. When the transfer assembly 24 takes and places the pole piece 71, the magnetic piece 72 or the magnetic bowl 73, the end of the positioning slider 14 is inserted into the corresponding positioning groove 131 and abuts against the tooling block 13 to position the tooling block 13, thereby improving the position stability of the tooling block 13 and further improving the placement accuracy of the parts.

[0036] like Figure 1 and 4As shown, the glue dispensing mechanism 3 includes glue injection needles 31. There are two groups of glue injection needles 31. The two groups of glue injection needles 31 are respectively located between the first centrifugal disk 21 and the second centrifugal disk 22, and between the second centrifugal disk 22 and the third centrifugal disk 23, and are used to apply glue to the upper surface of the pole piece 71 and the upper surface of the magnetic piece 72. In this embodiment, the glue material adopts AB glue, so the number of times of glue application at each glue application position is two. The glue dispensing mechanism 3 also includes a glue injection rack 32 and a cleaning assembly. A tank body for storing glue material is fixedly installed on the glue injection rack 32, and the glue injection needles 31 are located below the tank body; the glue injection rack 32 is slidably connected to the frame 1, and a cylinder for controlling the movement of the glue injection rack 32 is provided on the frame 1. The glue injection rack 32 carries the tank body and the glue injection needles 31 to move in two dimensions perpendicular to the moving direction of the tooling block 13. The cleaning assembly includes a cleaning box 33 and a cleaning sponge. The cleaning box 33 is fixedly connected to the frame 1. The cleaning sponge is located in the cleaning box 33 (not shown in the figure). The glue injection rack 32 allows the needle tip of the glue injection needle 31 to be inserted into the cleaning sponge. With long-term use, the needle tip of the glue injection needle 31 will have residual solidified glue. It can be set that after a certain number of glue dispensing cycles, the glue injection rack 32 controls the needle tip of the glue injection needle 31 to be inserted into the cleaning box 33 and causes the needle tip and the cleaning sponge to rub to remove the solidified glue on the needle tip.

[0037] like Figure 1-3 As shown, the upper surface of the tooling block 13 is formed with a positioning edge 132 for positioning each part, and the positioning edge 132 is in the shape of a rectangular frame; when placed correctly, the pole piece 71 and the magnetic piece 72 are located in the rectangular frame formed by the positioning edge 132, and the bending structure of the edge of the magnetic bowl 73 will be located outside the positioning edge 132. A pressure block 15 is also slidably arranged on the frame 1 and above the circulating slide 11, and the sliding direction is perpendicular to the upper surface of the tooling block 13; the pressure block 15 is located behind the first centrifugal disk 21, behind the second centrifugal disk 22, and behind the third centrifugal disk 23. A cylinder for controlling the downward movement of the pressure block 15 is installed on the frame 1. A pressure block 151 is elastically connected to the bottom of the pressure block 15 through a spring. After the corresponding parts are placed on the tooling block 13, they move downward. The pressure block 151 abuts and presses the top of the pole piece 71, the magnetic piece 72 or the magnetic bowl 73 to correct the parts with slight placement deviations, thereby improving the stability and position accuracy of the corresponding parts placed on the tooling block 13.

[0038] like Figure 1 , 4As shown in Figure 5, a rejection mechanism 6 is also provided on the frame 1 beside the circulating slide 11. The rejection mechanism 6 includes a detection sensor 61 and a material return assembly 62. The rejection mechanism 6 is located after the pressure block 15 behind the third centrifugal disk 23. The rejection mechanism 6 includes a detection sensor 61 and a material return assembly 62. The detection sensor 61 is used to detect the placement of parts on the tooling block 13. If it is detected that the parts are not placed correctly or there is a problem with the assembly of the parts, the detection sensor 61 will control the material return assembly 62 to reject the corresponding parts here. A top piece hole 12 is vertically opened on the upper edge of the circulating slide 11, and a clearance hole 133 is vertically opened on the upper edge of the tooling block 13. The clearance hole 133 is located within the rectangular frame formed by the positioning edge 132. When the pole piece 71 is placed on the tooling block 13, the upper port of the clearance hole 133 is blocked. In this embodiment, the detection sensor 61 works by a mechanism combining visual detection and infrared detection.

[0039] like Figure 4 and 5 As shown, the material removal assembly 62 includes a lifting cylinder 621 and a horizontal push cylinder 622, both of which are fixedly connected to the frame 1, the lifting cylinder 621 is located below the circulating slide 11 and the piston rod is coaxial with the top piece hole 12, the piston rod of the horizontal push cylinder 622 is in the horizontal direction and perpendicular to the length direction of the circulating slide 11, and after the lifting cylinder 621 extends the piston rod, the end of the piston rod passes through the top piece hole 12 and the clearance hole 1 33, the piston rod of the lifting cylinder 621 abuts against the lower side of the pole piece 71 and lifts it to the height of the piston rod of the horizontal push cylinder 622, and then the piston rod of the horizontal push cylinder 622 extends and hits the side edge of the magnetic bowl 73, and the parts are subjected to the lateral thrust and fly out in the horizontal direction; a waste trough 16 is provided on the frame 1 and on the side of the circulation slide 11 away from the horizontal push cylinder 622, and the parts subjected to the thrust of the horizontal push cylinder 622 fall into the waste trough 16 for collection. If the loudspeaker magnetic circuit 7 on the tooling block 13 passes the detection of the detection sensor 61, its assembly process is completed and it is about to enter the hot drying channel 17.

[0040] like Figure 1 and 4As shown, in order to increase the existence time of each workpiece block in the hot drying channel 17, the various tooling blocks 13 are first grouped in front of the hot drying channel 17, with four tooling blocks 13 forming a group. The arrangement direction of the four tooling blocks 13 is perpendicular to the length direction of the hot drying channel 17, and the single travel distance of each group of tooling blocks 13 is also the length of one tooling block 13, but the stagnation time is four times the single travel stagnation time of the tooling blocks 13 at the feeding mechanism 2. The conveying device 5 includes a first reversing cylinder 51, a grouping cylinder 52, a conveyor belt 53 and a hot drying cylinder 54. After the tooling block 13 passes through the material return assembly 62, the first reversing cylinder 51 pushes the tooling block 13 in the horizontal and vertical directions. The conveyor belt 53 is located on the frame 1, and its conveying direction is consistent with the extension and retraction direction of the piston rod of the first reversing cylinder 51; after the first reversing cylinder 51 pushes eight tooling blocks 13, the grouping cylinder 52 pushes the eight tooling blocks 13 together in the horizontal and vertical directions again, and the pushing direction of the grouping cylinder 52 is perpendicular to the conveying direction of the conveyor belt 53, so that the eight tooling blocks 13 are moved to the conveyor belt 53 at the same time, and the eight tooling blocks 13 are divided into two groups. A pressure block 15 is also provided on the frame 1 and between the grouping cylinder 52 and the conveyor belt 53. When a row of eight tooling blocks 13 are waiting to enter the conveyor belt 53, the pressure block 15 here can pressurize the speaker magnetic circuit 7 on the tooling block 13 below to improve the fit between parts and the uniformity of the diffusion of the rubber between two adjacent parts. After the conveyor belt 53 is started, the tooling blocks 13 on it can be transported to the starting end of the hot drying channel 17. The hot drying cylinder 54 is located at the starting end of the hot drying channel 17, and its propulsion direction is also perpendicular to the conveying direction of the conveyor belt 53 and parallel to the length direction of the hot drying channel 17. A single propulsion of the hot drying cylinder 54 can move four tooling blocks 13 toward the hot drying channel 17 by a body length.

[0041] like Figure 1 and 4As shown, the conveying device 5 also includes a second reversing cylinder 55, the propulsion direction of the second reversing cylinder 55 is perpendicular to the length direction of the hot drying channel 17. When the tooling block 13 drives out of the hot drying channel 17, the second reversing cylinder 55 controls the tooling block 13 to move in the horizontal and vertical directions, and moves a body distance at a time. The tooling block 13 continues to move to the unloading assembly 4, and the unloading assembly 4 removes the speaker magnetic circuit 7 on the tooling block 13. The mechanism principle of removal is similar to that of the transfer block 241, which will not be repeated here; the unloading assembly 4 includes a finished product tray 42, which is placed on the frame 1 and located next to the circulating slide 11. The removed products fall on the finished product tray 42 for collection. The unloading assembly 4 also includes a distance sensor 41. After the product is removed, the distance sensor 41 continues to move and is detected by the distance sensor 41. When it is detected that the product has not been removed, the conveying device 5 is controlled to stop running and send an alarm signal to remind the operator to manually take the product. Then the top of the tooling block 13 is left empty, and it continues to move to the loading mechanism 2 to place the parts again.

[0042] Embodiment 2: like Figure 5 As shown, in embodiment 1, the operation of the material return assembly 62 is achieved through the cooperation of the lifting cylinder 621 and the horizontal pushing cylinder 622. Since the magnetic bowl 73 is thin and small in size, the smooth progress of the rejection process requires high position accuracy of the piston rod of the lifting cylinder 621 and the piston rod of the horizontal pushing cylinder 622, and collision of the piston rods of the two should be avoided as much as possible.

[0043] like Figure 6 As shown, on the basis of Example 1, in this embodiment, the piston rod end of the lifting cylinder 621 is hingedly provided with an auxiliary block 623, the hinge axis is parallel to the length direction of the circulating slide 11, and the hinge axis is located on the side of the piston rod of the lifting cylinder 621 away from the horizontal thrust cylinder 622; the top of the auxiliary block 623 is slidably provided with an auxiliary plate 624, and after the piston rod of the lifting cylinder 621 rises, the plate surface of the auxiliary plate 624 away from the side of the auxiliary block 623 will be in contact with the magnetic sheet 72. An initial position spring 625 is connected between the auxiliary plate 624 and the auxiliary block 623, a torsion spring is provided on the hinge shaft between the auxiliary block 623 and the piston rod of the lifting cylinder 621, and an auxiliary pull rope 626 is connected between the auxiliary plate 624 and the piston rod of the lifting cylinder 621. In a natural state, the top surface of the auxiliary block 623 is parallel to the upper surface of the tooling block 13, the sliding direction of the auxiliary plate 624 relative to the auxiliary block 623 is parallel to the extension and retraction direction of the piston rod of the lifting cylinder 621, and the auxiliary pull rope 626 is in a tensioned state.

[0044] like Figure 6As shown, when rejecting, the piston rod of the lifting cylinder 621 moves upward, the auxiliary block 623 and the auxiliary rod pass through the top piece hole 12 and the clearance hole 133, and then the piston rod of the horizontal push cylinder 622 moves horizontally, and the piston rod end of the horizontal push cylinder 622 abuts against the edge of the magnetic bowl 73 and the side wall of the auxiliary block 623. After the auxiliary block 623 is subjected to the horizontal thrust, it swings toward the side of the waste tank 16; at the same time, because the distance between the connection point on the auxiliary plate 624 and the auxiliary pull rope 626 relative to the piston rod end of the lifting cylinder 621 becomes longer, the auxiliary pull rope 626 has a tendency to lengthen, and the auxiliary plate 624 is pulled and moves close to the auxiliary block 623, so that the parts on the auxiliary plate 624 are also easier to separate from the auxiliary plate 624, thereby improving the success rate of rejection. And because the piston rod of the horizontal push cylinder 622 will inevitably collide with the auxiliary block 623, the accuracy requirement of its installation position is greatly reduced.

[0045] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
