Description

Technical Field

[0001] The present application relates to the field of inner-pressed gecko processing technology, and in particular to an inner-pressed assembly machine. Background Art

[0002] An internal anchor refers to a fastener that is directly driven into a hole. An internal anchor usually includes a sleeve and an internal plug. After the internal anchor is placed in the wall hole, a screw is driven in. The screw drives the internal plug to push open the sleeve, causing the sleeve to expand and achieve a fixing effect.

[0003] At present, the inner force plug is usually assembled manually, that is, the staff places the inner force plug on the casing, and then uses a flat head screw to support the inner force plug, and uses a hammer to hammer the screw so that the inner force plug is pushed into the inner force expansion part of the casing, and finally screws are screwed into the casing to support the inner force plug to prevent the inner force plug from being squeezed out of the casing; however, in the face of larger production needs, the traditional manual assembly has low installation efficiency and is difficult to meet large-scale production needs. Summary of the invention

[0004] In order to improve the installation efficiency of the internally pressed wall anchor, the present application provides an internally pressed assembly machine.

[0005] The present application provides an internal pressure assembly machine that adopts the following technical solution:

[0006] An inner forced plug assembly machine comprises a workbench, a turntable, a motor, a placement seat, a feeding mechanism, a pressing mechanism and a limiting mechanism, wherein the turntable is rotatably arranged on the workbench, the motor is arranged on the workbench, and the output shaft of the motor is coaxially connected with the turntable; a plurality of placement seats are arranged on the turntable, and a receiving groove for accommodating a sleeve is provided on the placement seat; the feeding mechanism is arranged on the workbench and is used to drive the inner forced plug into the sleeve; the pressing mechanism is arranged on the workbench and is used to press the inner forced plug into the sleeve; the limiting mechanism is arranged on the workbench and is used to limit the inner forced plug from being removed from the sleeve.

[0007] By adopting the above technical solution, the staff places the sleeve in the accommodating groove on the placement seat, the motor drives the turntable to rotate, and the turntable drives the placement seat to move to the loading mechanism, the loading mechanism drives the inner forced plug into the sleeve, and then the pressing mechanism presses the inner forced plug into the inner forced expansion part in the sleeve, and finally the limiting mechanism limits the inner forced plug from being moved out of the sleeve, so that the assembly of the inner forced anchor is completed, and the motor drives multiple placement seats to rotate, so as to realize the assembly of the inner forced anchor in an assembly line manner, which effectively improves the installation efficiency of the inner forced anchor.

[0008] Optionally, the pressing mechanism includes a first cylinder and a pressing rod, the first cylinder is arranged on the workbench, the pressing rod is arranged on the piston rod of the first cylinder, and the pressing rod is opposite to the accommodating groove on the placement seat.

[0009] By adopting the above technical solution, when the turntable drives the placement seat to rotate to the position of the pressing rod and aligns the pressing rod with the receiving groove on the placement seat, the piston rod of the first cylinder extends, causing the pressing rod to move towards the placement seat. The pressing rod abuts against the internal forced plug on the sleeve and continues to move towards the sleeve, and then the internal forced plug can be pressed into the internal forced expansion part inside the sleeve.

[0010] Optionally, the pressing mechanism further includes a second cylinder, a sliding seat, a pressing seat and a spring. The second cylinder is arranged on the workbench. The sliding seat is slidably arranged on the workbench. The sliding seat is connected to the piston rod of the second cylinder. The first cylinder is arranged on the sliding seat. The pressing seat is slidably arranged on the sliding seat. The spring is arranged on the sliding seat and is connected to the pressing seat. A limiting hole for the pressing rod to insert is formed in the pressing seat.

[0011] By adopting the above technical solution, when the placement seat rotates to the bottom of the pressing seat, the piston rod of the second cylinder extends, driving the sliding seat and the pressing seat to slide towards the placement seat. The sliding seat abuts against the sleeve on the placement seat, pressing the sleeve tightly in the placement seat, improving the stability of the sleeve in the receiving groove. When the pressing seat abuts against the sleeve, the spring provides buffering for the pressing seat to prevent the pressing seat from damaging the sleeve due to excessive impact on the sleeve. Then the pressing rod passes through the limiting hole under the action of the first cylinder and then abuts against the internal forced plug.

[0012] Optionally, the feeding mechanism includes a material box and a third cylinder. The material box is arranged on the workbench. A conveying channel for conveying the internal forced plug is vertically arranged in the material box. A conveying channel is arranged in the pressing seat. The conveying channel is communicated with the conveying channel, and the end of the conveying channel far away from the conveying channel is directly opposite to the receiving groove on the placement seat. The third cylinder is arranged on the material box, and the third cylinder is used to push the internal forced plug in the conveying channel into the conveying channel.

[0013] By adopting the above technical solution, the staff sequentially loads several internal forced plugs into the conveying channel in the material box. The piston rod of the third cylinder extends, and the internal forced plug in the conveying channel can be pushed into the conveying channel, and then falls into the sleeve in the receiving groove from the conveying channel. Then the piston rod of the third cylinder retracts, and the internal forced plug in the conveying channel moves downward under the action of gravity, facilitating the next push of the third cylinder, thereby realizing the automatic feeding of the internal forced plug and improving the convenience for the staff to place the internal forced plug into the sleeve.

[0014] Optionally, the limiting mechanism includes a reel, a limiting belt, a support seat, a cutting cylinder, a fourth cylinder, and a clamping assembly. The reel is rotatably arranged on the workbench. The limiting belt is wound around the reel, and the limiting belt slidably penetrates through the pressing seat. The support seat is arranged on the sliding seat. The cutting cylinder is arranged on the support seat, and the cutting cylinder slidably penetrates through the limiting hole. The pressing rod is slidably arranged in the cutting cylinder. The fourth cylinder is arranged on the pressing seat. The clamping assembly is arranged on the piston rod of the fourth cylinder and is used for clamping the limiting belt.

[0015] By adopting the above technical solution, during the process of the sliding seat moving towards the placing seat, the pressing seat first abuts against the sleeve. The second cylinder continues to drive the sliding seat to move towards the placing seat. The sliding seat drives the support seat to move towards the limiting belt. The support seat drives the cutting cylinder to move towards the limiting belt. The cutting cylinder passes through the limiting hole and cuts out a disc on the limiting belt. The limiting hole restricts the moving direction of the cutting cylinder and improves the stability of the cutting cylinder's movement. Then the pressing rod penetrates into the cutting cylinder to push the disc into the sleeve. The disc is stuck on the thread in the sleeve, so that the internal pressing plug can be restricted from moving out of the sleeve. Then the sliding seat moves away from the placing seat. The fourth cylinder drives the clamping assembly to move. Since the clamping assembly clamps the limiting belt, the clamping assembly can clamp the limiting belt to the next uncut position.

[0016] Optionally, the clamping assembly includes a first clamping plate, a second clamping plate, and a fifth cylinder. The first clamping plate is arranged on the piston rod of the fourth cylinder. The second clamping plate is arranged on the piston rod of the fifth cylinder. The limiting belt is located between the first clamping plate and the second clamping plate. The fifth cylinder is arranged on the first clamping plate.

[0017] By adopting the above technical solution, the fourth cylinder drives the first clamping plate to move. At this time, the limiting belt is clamped between the first clamping plate and the second clamping plate. Therefore, the limiting belt is pulled. Then the piston rod of the fourth cylinder is driven to extend and reset, and at the same time, the piston rod of the fifth cylinder is driven to retract. The fourth cylinder drives the first clamping plate to reset. During the reset process, the clamping of the limiting belt by the first clamping plate and the second clamping plate is cancelled, preventing the first clamping plate and the second clamping plate from driving the reset belt to move during the reset process. When the fourth cylinder drives the first clamping plate to complete the reset, the piston rod of the fifth cylinder is then driven to extend, and the reset belt is clamped between the first clamping plate and the second clamping plate.

[0018] Optionally, a discharging mechanism for driving the sleeve to move out of the accommodating groove is arranged on the workbench. The discharging mechanism includes a sixth cylinder and an elastic piece. The sixth cylinder is arranged on the workbench. The elastic piece is arranged on the piston rod of the sixth cylinder. A sliding groove for the elastic piece to slide into is formed in the placing seat and is communicated with the accommodating groove.

[0019] By adopting the above technical solution, when the turntable drives the placement seat to rotate to the unloading mechanism, the piston rod of the sixth cylinder extends, causing the elastic piece to slide into the chute. The elastic piece abuts against the sleeve, and then the piston rod of the sixth cylinder continues to extend, and the elastic piece pushes the sleeve out of the receiving groove. Then the piston rod of the sixth cylinder retracts, causing the elastic piece to move out of the chute, and the sleeve can be pushed out of the receiving groove, effectively improving the convenience for the staff to drive the sleeve out of the receiving groove.

[0020] Optionally, a discharge chute is provided on the workbench at the position of the unloading mechanism, and a baffle is provided on the discharge chute for driving the popped internal expansion plug to move into the discharge chute.

[0021] By adopting the above technical solution, the sleeve pushed out of the receiving groove is blocked by the baffle, causing the internal expansion plug to fall into the discharge chute for collection, effectively improving the convenience for the staff to collect the installed internal expansion plugs.

[0022] Optionally, a detection mechanism for detecting whether the internal expansion plug enters the internal expansion part of the sleeve is provided on the workbench. The detection mechanism includes a seventh cylinder, a sliding rod, a pressure sensor and a controller. The seventh cylinder is arranged on the workbench, the sliding rod is arranged on the piston rod of the seventh cylinder, and the sliding rod is telescopic; the pressure sensor is arranged inside the sliding rod. When the sliding rod abuts against the internal expansion plug at the upper end of the internal expansion part located inside the sleeve, the lower section of the sliding rod abuts against the pressure sensor; the controller is arranged on the workbench, the controller is electrically connected to the pressure sensor, and a discharge mechanism is also arranged on the workbench at the position of the detection mechanism, and the controller is electrically connected to the sixth cylinder at the position of the detection mechanism.

[0023] By adopting the above technical solution, when the placement seat rotates to the position of the sliding rod, the piston rod of the seventh cylinder extends, causing the sliding rod to extend into the sleeve. When the sliding rod abuts against the internal expansion plug at the upper end of the internal expansion part located inside the sleeve, the lower end of the sliding rod abuts against the pressure sensor, and the pressure sensor sends an electrical signal to the controller. The controller controls the piston rod of the sixth cylinder of the discharge mechanism at the position of the detection mechanism to extend, causing the elastic piece to push the sleeve out of the receiving groove, avoiding the internal expansion plugs with the internal expansion plug not entering the internal expansion part of the sleeve from being mixed into the finished products, and eliminating the subsequent manual screening process for the staff.

[0024] Optionally, a limiting tube is provided on the bottom wall of the receiving groove. The outer diameter of the limiting tube is smaller than the inner diameter of the sleeve, and the inner diameter of the limiting tube is larger than the outer diameter of the internal expansion plug.

[0025] By adopting the above technical solution, when the staff puts the sleeve into the receiving groove, the sleeve is sleeved on the limiting tube. Subsequently, when the internal pressing plug is pressed into the sleeve, the limiting tube provides a limit for the internal pressing plug, preventing the internal pressing plug from being pushed out of the internally expanding part of the sleeve, so that the internal pressing plug can only possibly be located above the internally expanding part of the sleeve inside the sleeve, improving the yield rate of the production of internal pressing geckos, and improving the accuracy of subsequent detection mechanisms for detecting whether the internal pressing plug enters the internally expanding part of the sleeve.

[0026] In summary, the present application includes at least one of the following beneficial technical effects:

[0027] 1. By driving a plurality of placing seats to rotate with a motor, the feeding mechanism drives the internal pressing plug into the sleeve, the pressing mechanism presses the internal pressing plug into the internally expanding part of the sleeve, and the limiting mechanism restricts the internal pressing plug from moving out of the sleeve, realizing a pipeline-type assembly of internal pressing geckos and effectively improving the installation efficiency of internal pressing geckos;

[0028] 2. The second air cylinder drives the sliding seat and the pressing seat to slide in the direction close to the placing seat. The sliding seat abuts against the sleeve on the placing seat, pressing the sleeve tightly in the placing seat, improving the stability of the sleeve in the receiving groove. Moreover, when the pressing seat abuts against the sleeve, the spring provides buffering for the pressing seat, preventing the pressing seat from damaging the sleeve due to excessive impact on the sleeve;

[0029] 3. The detection mechanism detects whether the internal pressing plug enters the internally expanding part of the sleeve, and ejects the sleeve in which the internal pressing plug does not enter the internally expanding part of the sleeve, avoiding the mixing of internal pressing geckos in which the internal pressing plug does not enter the internally expanding part of the sleeve into the finished products, and eliminating the subsequent manual screening process for the staff.

Detailed implementation manners

[0037] The following further elaborates on this application Figures 1-6 in detail with reference to the appended drawings.

[0038] The embodiment of this application discloses an internal pressing assembly machine.

[0039] Referring to Figure 1 , the internal pressing assembly machine includes a workbench 1, a turntable 2, a motor 3, a placing seat 4, a feeding mechanism 5, a pressing-in mechanism 6, and a limiting mechanism 7.

[0040] In this embodiment, a placing tabletop is installed on the side wall of the workbench 1, which facilitates the operator to place the sleeve on the placing tabletop, and then pick up the sleeve from the placing tabletop and place it on the placing seat 4. A plurality of universal wheels are installed at the bottom of the workbench 1, which facilitates the operator to move the workbench 1. Moreover, adjustable support feet are also installed at the bottom of the workbench 1. After moving the workbench 1 to the working station, the support feet are adjusted to lift the workbench 1, improving the stability of the workbench 1.

[0041] Referring to Figure 1 , the turntable 2 is rotatably installed on the workbench 1, the motor 3 is installed inside the workbench 1, and the output shaft of the motor 3 is connected to the turntable 2 in a communicating manner; a plurality of placing seats 4 are circumferentially spaced around the center of the turntable 2 on the turntable 2. A receiving groove 41 for inserting the sleeve is provided on the placing seat 4. In this embodiment, two receiving grooves 41 are spaced apart on one placing seat 4, so that one placing seat 4 can place two sleeves, and the two sleeves are processed synchronously later, improving the installation efficiency of the internal pressing gecko; the feeding mechanism 5 is installed on the workbench 1, and the feeding mechanism 5 is used to drive the internal pressing plug into the sleeve; the pressing-in mechanism 6 is installed on the workbench 1, and the pressing-in mechanism 6 is used to press the internal pressing plug on the sleeve into the internal pressing expansion part inside the sleeve; the limiting mechanism 7 is installed on the workbench 1, and the limiting mechanism 7 is used to limit the internal pressing plug from moving out of the sleeve.

[0042] The staff respectively place the two sleeves placed on the placement table into the two receiving grooves 41 opened on the placement table. The motor 3 drives the turntable 2 to rotate, and the turntable 2 drives the placement seat 4 to rotate. When the placement seat 4 rotates to the feeding mechanism 5, the feeding mechanism 5 drives the internal plug to enter the sleeve, and then the pressing mechanism 6 presses the internal plug into the internally pressed expansion part in the sleeve. The limiting mechanism 7 restricts the internal plug from moving out of the sleeve, and thus the assembly of two internally pressed geckos can be completed. By driving multiple placement seats 4 to rotate through the motor 3, the internal plugs are sequentially pressed into the sleeves on different placement seats 4, realizing the assembly of internally pressed geckos in a pipeline manner, effectively improving the installation efficiency of internally pressed geckos.

[0043] Refer to Figure 1 、 Figure 2 Figure, the pressing mechanism 6 includes a first cylinder 61, a pressing rod 62, a second cylinder 63, a sliding seat 64, a pressing seat 65 and a spring 66. The second cylinder 63 is vertically installed on the workbench 1. The sliding seat 64 is slidably installed on the workbench 1 in the vertical direction. The sliding seat 64 is connected to the piston rod of the second cylinder 63. The pressing seat 65 is slidably installed on the sliding seat 64. One end of the spring 66 is installed on the sliding seat 64 and the other end is installed on the pressing seat 65. In this embodiment, two guide rods are installed on the sliding seat 64 at intervals in the vertical direction. The pressing seat 65 slides on the two guide rods to improve the stability of the pressing seat 65 when sliding. And the spring 66 is sleeved on the guide rod, and the guide rod can also improve the stability of the spring 66 when stretching and contracting. The first cylinder 61 is installed on the sliding seat 64. In this embodiment, a support plate is installed on the piston rod of the first cylinder 61. Two pressing rods 62 are installed on the support plate at intervals. The distance between the two pressing rods 62 is the same as the distance between the centers of the two receiving grooves 41 on the same placement seat 4, and the two pressing rods 62 are respectively opposite to the two receiving grooves 41 on the placement seat 4.

[0044] Combined with Figure 3, the feeding mechanism 5 includes a material box 51 and a third cylinder 52. The material box 51 is installed on the workbench 1. In this embodiment, two guide rails are installed on the side wall of the material box 51 in the vertical direction, and the sliding seat 64 is slidably installed on the guide rails, making the sliding of the sliding seat 64 more stable; two conveying channels 511 for conveying internal plugs are installed at intervals in the vertical direction in the material box 51, and a conveying channel 652 is installed on the pressing seat 65. When the sliding seat 64 is in the raised state, one end of the conveying channel 652 communicates with the conveying channel 511 and the other end is directly opposite to the receiving groove 41 on the placing seat 4. In this embodiment, a clamping groove is opened on the side wall of the conveying channel 652 near one end of the conveying channel 511, and a slider is slidably installed in the clamping groove. One end of the slider away from the bottom wall of the clamping groove is arc-shaped, and a telescopic spring is installed on the bottom wall of the clamping groove. The telescopic spring is connected to the slider and always has a tendency to drive the arc-shaped end of the slider out of the clamping groove, so that the clamping block can block the internal plug and prevent the internal plug from entering the conveying channel 652 due to mechanical vibration. However, when the third cylinder 52 pushes the internal plug, the internal plug can also squeeze the clamping block into the clamping groove. When the piston rod of the third cylinder 52 retracts, the clamping block can also be squeezed into the clamping groove by the piston rod of the third cylinder 52, so that the piston rod of the third cylinder 52 can be retracted; and in this embodiment, a feeding tray is installed on the material box 51, a vibration motor is installed in the feeding tray, and a feeding port for communicating with the conveying channel 511 is opened on the bottom wall of the feeding tray. The shape of the feeding port is the same as the shape of the internal plug. The staff pours a number of internal plugs into the feeding tray, and by driving the feeding tray to rotate through the vibration motor, the number of internal plugs can move in the feeding tray. When the internal plug moves to match the shape of the feeding port, the internal plug can automatically enter the conveying channel 511 from the feeding port, improving the convenience for the staff to drive the internal plug into the conveying channel 511 for arrangement; the third cylinder 52 is installed on the material box 51, and the third cylinder 52 is used to push an internal plug at the bottom of the conveying channel 511 into the conveying channel 511.

[0045] The staff pre-loads several internal plugs into the tray. The internal plugs are arranged in the conveying channel 511 in sequence from the tray. When the placing seat 4 rotates to the pressing seat 65, the piston rod of the third cylinder 52 extends, pushing one internal plug at the bottom of the conveying channel 511 into the transmission channel 652, and the internal plug falls into the bottom sleeve from the transmission channel 652. Then the piston rod of the third cylinder 52 retracts, and the internal plugs in the conveying channel 511 move downward under the action of gravity, facilitating the next push of the third cylinder 52, thereby realizing the automatic feeding of the internal plugs, improving the convenience for the staff to load several internal plugs into the conveying channel 511 in sequence, reducing the workload of the staff, and improving work efficiency. Then the piston rod of the second cylinder 63 extends, causing the sliding seat 64 and the pressing seat 65 to slide towards the placing seat 4. The pressing seat 65 presses the sleeve in the receiving groove 41 tightly between the sliding seat and the bottom wall of the receiving groove 41, improving the stability of the sleeve in the receiving groove 41. When the pressing seat 65 abuts against the sleeve, the spring 66 provides buffering for the pressing seat 65, and the pressing seat 65 can move away from the sleeve to prevent the pressing seat 65 from damaging the sleeve due to excessive impact on the sleeve. Then the piston rod of the first cylinder 61 extends, causing the two pressing rods 62 to move towards the placing seat 4. The pressing rods 62 pass through the limiting holes 651 and abut against the internal plugs in the sleeve, and push the internal plugs into the internal expansion part in the sleeve, completing the installation of the internal plugs and the sleeve.

[0046] Refer to Figure 2 , the limiting mechanism 7 includes a reel 71, a limiting belt 72, a support seat 73, a cutting cylinder 74, a fourth cylinder 75 and a clamping assembly 76. The reel 71 is rotatably installed on the workbench 1. The limiting belt 72 is wound around the reel 71, and the limiting belt 72 extends to the pressing seat 65 and slidably passes through the pressing seat 65. The support seat 73 is installed on the sliding seat 64. Two cutting cylinders 74 are spacedly installed on the support seat 73. The distance between the centers of the two cutting cylinders 74 is the same as the distance between the centers of the two receiving grooves 41. The cutting cylinder 74 slidably passes through the limiting hole 651, and the inner diameter of the cutting cylinder 74 is larger than the outer diameter of the pressing rod 62, so that the pressing rod 62 can pass through the cutting cylinder 74. The fourth cylinder 75 is installed on the pressing seat 65, and the clamping assembly 76 is installed on the piston rod of the fourth cylinder 75. The clamping assembly 76 is used to clamp the limiting belt 72. The clamping assembly 76 includes a first clamping plate 761, a second clamping plate 762 and a fifth cylinder 763. The first clamping plate 761 is installed on the piston rod of the fourth cylinder 75. The second clamping plate 762 is installed on the piston rod of the fifth cylinder 763. The first clamping plate 761 and the second clamping plate 762 are arranged vertically. The fifth cylinder 763 is installed on the first clamping plate 761. The limiting belt 72 is located between the first clamping plate 761 and the second clamping plate 762.

[0047] When the second cylinder 63 drives the sliding seat 64 and the pressing seat 65 to move towards the placing seat 4, the pressing seat 65 first abuts against the sleeve, and then the sliding seat 64 continues to move towards the placing seat 4 under the drive of the second cylinder 63. The sliding seat 64 drives the support seat 73 to continue to move towards the placing seat 4, and the support seat 73 drives the cutting cylinder 74 to move towards the limiting strip 72. After the cutting cylinder 74 passes through the limiting hole 651, it cuts out a disc on the limiting strip 72. The limiting hole 651 restricts the moving direction of the cutting cylinder 74, improves the stability of the movement of the cutting cylinder 74, and through the two-stage movement of the sliding seat 64 and the pressing seat 65, only one cylinder is needed to make the pressing seat 65 abut against the sleeve, and then the sliding seat 64 continues to drive the cutting cylinder 74 to cut the limiting strip 72; then the pressing rod 62 passes through the cutting cylinder 74 and presses the disc into the sleeve, and the disc is stuck on the thread in the sleeve, so as to restrict the inner pressing plug from moving out of the sleeve. Then the second cylinder 63 drives the sliding seat 64 away from the placing seat 4, and the pressing seat 65 resets under the action of the spring 66; then the fourth cylinder 75 drives the first clamping plate 761 to move. At this time, the limiting strip 72 is clamped between the first clamping plate 761 and the second clamping plate 762. Therefore, the limiting strip 72 is pulled by the first clamping plate 761, so that the limiting strip 72 moves away from the reel 71, and the cut part of the limiting strip 72 is pulled away from the pressing seat 65. Then the piston rod of the fourth cylinder 75 is driven to extend and reset, and at the same time, the piston rod of the fifth cylinder 763 is driven to retract. The fourth cylinder 75 drives the first clamping plate 761 to reset. During the reset process, the first clamping plate 761 and the second clamping plate 762 cancel the clamping of the limiting strip 72 to prevent the first clamping plate 761 and the second clamping plate 762 from driving the limiting strip 72 to move during the reset process. When the fourth cylinder 75 drives the first clamping plate 761 to complete the reset, the piston rod of the fifth cylinder 763 is then driven to extend, and the reset strip is clamped between the first clamping plate 761 and the second clamping plate 762.

[0048] Refer to Figure 4 , Figure 5, a detection mechanism 11 for detecting whether the internal forced expansion part of the internal forced plug enters the sleeve is installed on the workbench 1. The detection mechanism 11 includes a seventh cylinder 111, a sliding rod 112, a pressure sensor 113 and a controller 114. The seventh cylinder 111 is vertically installed on the workbench 1. In this embodiment, a connecting plate is installed on the piston rod of the seventh cylinder 111, and two sliding rods 112 are installed on the connecting plate at intervals. The distance between the centers of the two sliding rods 112 is the same as the distance between the centers of the two receiving grooves 41. The sliding rod 112 includes a large rod and a small rod. The large rod is installed on the connecting plate. The large rod is hollow inside and open at the end far from the connecting plate. The diameter of the open end of the large rod is smaller than the inner diameter of the large rod. The small rod is slidably installed on the large rod. An anti-detachment block is installed at the end of the small rod located inside the large rod. The diameter of the anti-detachment block is larger than the diameter of the open end of the large rod to prevent the small rod from detaching from the large rod. The pressure sensor 113 is installed on the inner bottom wall of the large rod. When the sliding rod 112 abuts against the internal forced plug at the upper end of the internal forced expansion part located inside the sleeve, that is, when the internal forced plug is at the upper end of the internal forced expansion part inside the sleeve, the small rod moves towards the large rod and abuts against the pressure sensor 113. The controller 114 is installed on the workbench 1. The controller 114 is electrically connected to the pressure sensor 113, and a discharging mechanism 8 is installed on the workbench 1 at the location of the detection mechanism 11. The discharging mechanism 8 is used to drive the sleeve out of the receiving groove 41. The controller 114 is electrically connected to the discharging mechanism 8.

[0049] After the internal forced plug is pressed into the sleeve by the pressing rod 62, the placing seat 4 rotates to the location of the detection mechanism 11 under the action of the motor 3. The piston rod of the seventh cylinder 111 extends, so that the sliding rod 112 moves towards the sleeve. The sliding rod 112 extends into the sleeve. When the internal forced plug enters the internal forced expansion part inside the sleeve, the distance between the internal forced plug and the sliding rod 112 is relatively far, and the small rod will not abut against the pressure sensor 113 on the inner bottom wall of the large rod. When the internal forced plug is at the upper end of the internal forced expansion part inside the sleeve, the distance between the internal forced plug and the sliding rod 112 is relatively close. After the small rod abuts against the internal forced plug, the small rod slides towards the large rod and abuts against the pressure sensor 113. The pressure sensor 113 sends an electrical signal to the controller 114. The controller 114 controls the discharging mechanism 8 to drive the sleeve out of the receiving groove 41, avoiding the internal forced gecko that the internal forced plug does not enter the internal forced expansion part inside the sleeve from being mixed into the finished product and eliminating the subsequent manual screening process for the staff.

[0050] Combined with Figure 6, and a limiting tube 12 is installed on the bottom wall of the accommodating groove 41. The outer diameter of the limiting tube 12 is smaller than the inner diameter of the sleeve, the inner diameter of the limiting tube 12 is larger than the diameter of the internal pressing plug, and the length of the limiting tube 12 is the distance between the bottom of the sleeve and the internal pressing expansion part inside the sleeve. When the staff puts the sleeve into the accommodating groove 41, the sleeve is sleeved on the limiting tube 12. When the internal pressing plug is pressed into the internal pressing plug, the limiting tube 12 restricts the internal pressing plug from continuing to be pushed out towards the direction close to the bottom of the accommodating groove 41 after entering the internal pressing expansion part of the sleeve, improving the yield rate of the production of the internal pressing gecko, and avoiding the internal pressing plug being pushed out of the internal pressing expansion part inside the sleeve, thereby improving the accuracy of the subsequent detection mechanism 11 for detecting whether the internal pressing plug enters the internal pressing expansion part inside the sleeve.

[0051] Refer to Figure 4 , Figure 6 , a discharging mechanism 8 is also installed at the next working station of the detecting mechanism 11. The discharging mechanism 8 includes a sixth cylinder 81 and a spring piece 82. The sixth cylinder 81 is installed on the workbench 1, the sixth cylinder 81 is electrically connected to the controller 114, the spring piece 82 is installed on the piston rod of the sixth cylinder 81, a sliding groove 42 for the spring piece 82 to slide into is formed in the placing seat 4 in communication with the accommodating groove 41, and an opening for the spring piece 82 to pass through is provided on the limiting tube 12; and a discharging groove 9 is installed on the workbench 1 at the position of the discharging mechanism 8, a baffle 10 is installed on the discharging groove 9 through a fastening bolt, and the baffle 10 is used to drive the internal pressing gecko ejected from the accommodating groove 41 to move into the discharging groove 9. In this embodiment, a sliding strip hole is formed in the baffle 10, the fastening bolt is located in the sliding strip hole, and the staff loosens the fastening bolt to drive the baffle 10 to slide on the discharging groove 9, adjust the position of the baffle 10, and then tighten the fastening bolt to make the fastening bolt press the baffle 10 tightly on the discharging groove 9.

[0052] When a defective product is detected, the controller 114 controls the piston rod of the sixth cylinder 81 to extend, the spring piece 82 moves towards the placing seat 4, the spring piece 82 slides into the sliding groove 42 and ejects the unqualified internal pressing gecko from the accommodating groove 41, and the ejected internal pressing gecko falls into the discharging groove 9 for discharging after the rebound of the baffle 10; when the placing seat 4 rotates to the discharging mechanism 8 at the lower moving station of the detecting mechanism 11, the piston rod of the sixth cylinder 81 here extends, and the spring piece 82 ejects the internal pressing gecko from the accommodating groove 41 for discharging, effectively improving the convenience for the staff to drive the sleeve out of the accommodating groove 41, and through the discharging groove 9 and the baffle 10, it is also convenient for the staff to collect the installed internal pressing gecko.

[0053] The implementation principle of an internal forced assembly machine in an embodiment of this application is as follows: The staff places the sleeve in the receiving groove 41 on the placement seat 4. The motor 3 drives the turntable 2 to rotate. The turntable 2 drives the placement seat 4 to rotate to the feeding mechanism 5 and the pressing mechanism 6. At this time, the third cylinder 52 and the piston rod extend, and an internal forced plug in the conveying channel 511 is pushed into the transmission channel 652. The internal forced plug falls into the sleeve from the transmission channel 652. Then, the piston rod of the second cylinder 63 extends, driving the sliding seat 64 and the pressing seat 65 to move towards the placement seat 4. After the pressing seat 65 abuts against the sleeve, the piston rod of the second cylinder 63 still moves downward, so that the sliding seat 64 drives the cutting cylinder 74 to still move downward. The cutting cylinder 74 cuts out a disc on the limiting belt 72. Then, the piston rod of the first cylinder 61 extends, so that the pressing rod 62 penetrates into the cutting cylinder 74. The pressing rod 62 presses the disc into the sleeve, and at the same time, the pressing plug is pushed out of the internal forced expansion part in the sleeve, completing the installation of the internal wave gecko. Then, the motor 3 drives the placement seat 4 to rotate to the detection mechanism 11. The seventh cylinder 111 drives the sliding rod 112 to extend into the sleeve. When the internal forced plug is located above the internal forced expansion part in the sleeve, the sliding rod 112 abuts against the pressure sensor 113. The pressure sensor 113 transmits an electrical signal to the controller 114. The controller 114 controls the sixth cylinder 81 at the detection mechanism 11. The sixth cylinder 81 drives the elastic piece 82 to eject the unqualified internal forced gecko from the receiving groove 41. When the sliding rod 112 does not abut against the pressure sensor 113, the motor 3 drives the placement seat 4 to rotate to the next station. The sixth cylinder 81 at this station starts, so that the elastic piece 82 slides into the chute 42, pushing out the qualified internal forced gecko. The internal forced gecko slides out of the discharge chute 9 for discharging. By driving multiple placement seats 4 to rotate through the motor 3, the assembly of the internal forced gecko in a pipeline manner is realized, effectively improving the installation efficiency of the internal forced gecko. And through the detection of the limiting tube 12 and the detection mechanism 11, the forming quality of the internal forced gecko is improved.

[0054] The above are all the preferred embodiments of this application, and the protection scope of this application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
