Description

Technical Field

[0001] This invention relates to a testing device, and more particularly to an automatic zipper head assembly device. Background Technology

[0002] Zippers are fasteners that use continuously arranged teeth to join or separate items. They are widely used in clothing, bags, tents, etc. The zipper pull, a major component of the zipper, consists of three parts, as shown in the attached diagram. Figure 1 As shown, the zipper head includes a zipper pull 101, a pull tab 102, and a spring tab 103. The zipper pull has two inlets and one engaging outlet, and is integrated with the lower plate via a support core. The pull tab has a sheet-like structure, and the part that contacts the zipper pull is wider than the user's grip. The pull tab and the zipper pull are connected together by a spring tab. Currently, all-metal zipper heads are produced using a relatively traditional semi-automatic method. This involves an operator assembling the zipper pull, pull tab, and spring tab, placing them into a mold, and manually controlling a cylinder to compress and deform the ends of the inlets, clamping the spring tab to complete the assembly. This traditional production method is inefficient and difficult to meet practical requirements. Given these shortcomings, it is necessary to design an automatic zipper head assembly device. Summary of the Invention

[0003] The purpose of this invention is to provide an automatic zipper head assembly device that can automatically complete the assembly of zipper heads, has extremely high production efficiency, and integrates detection functions to greatly improve the product qualification rate.

[0004] To solve the above-mentioned technical problems, the technical solution of the present invention is: an automatic zipper head assembly device, comprising a frame, a drive mechanism, a turntable, carriers, a detection and pressing mechanism, a zipper head vibratory feeder, a zipper head feeding mechanism, an alignment mechanism, a zipper tab vibratory feeder, a zipper tab feeding mechanism, a spring tab vibratory feeder, a spring tab feeding mechanism, a first pulling mechanism, a clamping mechanism, and a second pulling mechanism. The drive mechanism is installed at the lower end of the frame, the turntable is installed at the upper end of the drive mechanism, and the number of carriers is not less than two, arranged at equal intervals along the circumference of the turntable. The detection and pressing mechanism is located at... Above the turntable and connected to the drive mechanism, the pull head vibratory plate, pull head feeding mechanism, alignment mechanism, pull plate vibratory plate, pull plate feeding mechanism, spring plate vibratory plate, spring plate feeding mechanism, first pulling mechanism, clamping mechanism, and second pulling mechanism are arranged sequentially along the circumference of the turntable on the upper end of the frame. The pull head feeding mechanism is connected to the pull head vibratory plate, the pull plate feeding mechanism is connected to the pull plate vibratory plate, the spring plate feeding mechanism is connected to the spring plate vibratory plate, and the clamping mechanism is connected to the drive mechanism. The first pulling mechanism and the second pulling mechanism have the same structure.

[0005] The invention is further improved as follows: Furthermore, the drive mechanism includes a motor, a bracket, a divider, a bearing housing, a rotating shaft, a belt drive mechanism, a right eccentric assembly, a connecting rod, a slider, a driving gear, a driven gear, a left eccentric assembly, a support shaft, a stabilizing disc, and a guide rod. The motor is mounted at the bottom of the frame, the bracket is mounted on the upper part of the frame, the divider is mounted on the upper end of the bracket and fixed to the lower end of the turntable, the bearing housing is fixed to the lower end of the bracket, the rotating shaft passes through the bearing housing, the two ends of the belt drive mechanism are respectively connected to the rotating shaft and the motor, the right eccentric assembly is mounted on the right end of the rotating shaft, the connecting rod is located on the upper end of the right eccentric assembly, the slider is located on the upper end of the connecting rod and on the lower end of the clamping mechanism, and the slider rotates in relation to the connecting rod. The drive gear is mounted on the middle of the rotating shaft, and the driven gear is mounted on the outside of the divider and meshes with the drive gear. The left eccentric assembly is installed on the left end of the rotating shaft. The support shaft is located above the left eccentric assembly and passes through the divider and the detection pressing mechanism in sequence. The support shaft is rotatably connected to the left eccentric assembly and to the detection pressing mechanism. The stabilizing plate is located above the divider and above the turntable. The stabilizing plate is bolted to the divider. The guide rod passes through the detection pressing mechanism and is located above the stabilizing plate. The guide rod is bolted to the stabilizing plate. The detection pressing mechanism slides along the guide rod. The structure of the right eccentric assembly is the same as that of the left eccentric assembly. The structure is the same as that of the other components. The right eccentric assembly includes a connecting plate, a first rotating pin, a connecting arm, and a second rotating pin. The connecting plate is connected to the rotating shaft, and the first rotating pin is connected to the connecting plate. The axis of the first rotating pin does not coincide with the axis of the connecting plate. The connecting arm is penetrated by the first rotating pin, and the connecting arm and the first rotating pin are connected with a clearance fit. The second rotating pin penetrates the connecting arm, and the second rotating pin is connected with the connecting arm with a clearance fit. The connecting plate is fixed on the fixing sleeve of the divider. The guide rod fixed to the connecting plate is used to maintain the smooth movement of the detection pressing mechanism. The motor drives the rotating shaft to rotate through a belt drive mechanism. The rotating shaft can simultaneously drive the connecting plate and the drive gear in both the right eccentric assembly and the left eccentric assembly. When the right eccentric assembly is working, the connecting plate drives the connecting arm to rotate through the eccentric first rotating pin, which in turn drives the slider to slide along the vertical direction of the frame via the connecting rod, thereby driving the wedge-shaped push head inside the clamping mechanism to slide up and down. When the left eccentric assembly rotates, the connecting plate drives the connecting arm to rotate through the eccentric first rotating pin, which in turn drives the support shaft to move up and down along the guide rod via the detection plate. However, when the driving gear drives the driven gear to rotate, the drive divider drives the carrier on the turntable to move, thus enabling it to move to different work positions for corresponding operations. The above movements are linked, that is, when the divider rotates to a position at equal intervals, the right eccentric assembly and the left eccentric assembly respectively drive the clamping mechanism and the detection pressing mechanism to reciprocate once.

[0006] Furthermore, the carrier includes a carrier base, a third rotating pin, a rocker block, a positioning block, a first spring, a first limiting groove, a steel ball, an adjusting screw, a second spring, a positioning tongue, and a nylon tongue. The carrier base is fixed to the upper end of the turntable. The third rotating pin passes through the carrier base. The rocker block is located at the upper end of the carrier base and is passed through by the third rotating pin. The rocker block and the third rotating pin are connected with a clearance fit. The positioning block is located between the rocker block and the carrier base and is connected to the carrier base. The first spring passes through the positioning block and is located between the rocker block and the carrier base. The first limiting groove is formed on one side of the positioning block. The steel ball is placed in the first limiting groove. The adjusting screw is fixed to the upper end of the first limiting groove. The second spring is located between the adjusting screw and the steel ball. The positioning tongue is located at... On the right side of the positioning block, the positioning tongue is integrally connected to the positioning block, and the nylon tongue is set at the top of the positioning tongue. When the first cylinder drives the pusher head to push the pull head, the positioning tongue and the cavity of the pull head are aligned. With the movement of the first cylinder, the positioning tongue and the nylon tongue are inserted into the pull head, thereby clamping and positioning the pull head. Due to the slight deformation inside the nylon tongue, it plays a clamping role on the one hand, and prevents scratches on the inner surface of the pull head on the other hand. When the second cylinder drives the pressure arm to push the pusher teeth to press the pull piece into the carrier, the rocker block rotates slightly along the third rotating pin to form a certain cavity with the pull head to accommodate the pull piece. During this process, the steel ball in the first limiting groove is pushed upward by the force, and the second spring reacts to the steel ball to lightly press the pull piece and the pull head together. The adjusting screw can adjust the degree of deformation of the second spring, thereby adjusting the clamping effect.

[0007] Furthermore, the detection pressing mechanism includes a detection plate, a detection component, and a pressing component. The detection plate is penetrated by a support shaft, and the detection plate is connected to the support shaft by bolts. The axis of the detection plate coincides with the axis of the turntable. The detection component includes a first clamp, a detection needle rod, a third spring, and a fiber optic sensor. The first clamp is located at the edge of the detection plate, the detection needle rod slides along the vertical direction of the first clamp, the third spring is located at the lower end of the first clamp and outside the detection needle rod, and the fiber optic sensor is located at the top of the first clamp. The pressing component includes a second clamp, a pressing die, and a fourth spring. The second clamp is located at the edge of the detection plate, the pressing die slides along the vertical direction of the second clamp, and the fourth spring is located at the upper end of the pressing die and inside the second clamp. The detection plate moves downward with the support shaft, and when the detection... When the probe rod detects that the pull tab and pull head are in the normal installation position, the probe rod moves upward to trigger the fiber optic sensor. The control system records this station as a good product station. When the transfer is completed, the good product is pulled out by the second pulling mechanism. However, when the pull tab and pull head are in the abnormal installation position, the probe rod cannot trigger the fiber optic sensor. The control system records this station as a defective product station and does not perform subsequent processes. The defective product is pulled out by the first pulling mechanism. By setting multiple sets of detection components, such as after the pull head, pull tab, and spring are loaded into the carrier, the yield rate of assembly can be guaranteed to a greater extent. The pressing die moves down with the support shaft and contacts the aligned but not pressed pull head, pull tab, and spring. The fourth spring deforms and lightly presses the aligned but not pressed pull head, pull tab, and spring. The clamping mechanism bites the contact surface of the pull head and spring, causing deformation, thereby completing the assembly.

[0008] Furthermore, the pull head feeding mechanism includes a pull head feeding track, a first cylinder, and a push head. The pull head feeding track is located outside the pull head vibrating plate, the first cylinder is located at the bottom of the pull head feeding track, and the push head is connected to the first cylinder and faces the turntable. The push head also has a baffle groove and a guide part. The baffle groove is located at the right end of the push head and passes through the push head. The guide part is located at the left end of the baffle groove, and the angle between the guide part and the horizontal plane is an acute angle. The pull head vibrating plate continuously feeds material to the pull head feeding track inside the pull head feeding mechanism, and the material is guided by the guide part to be conveyed into the baffle groove. The first cylinder drives the push head to convey the pull head into the carrier. Due to the limiting effect of the baffle groove, the positioning tongue and nylon tongue in the carrier are inserted into the cavity at the tail of the pull head, thereby completing the feeding of the pull head.

[0009] Furthermore, the alignment mechanism includes an alignment seat, an alignment arm, a fifth spring, a bearing, and an adjusting bolt. The alignment seat is located at the upper end of the frame, the alignment arm is rotatably connected to the alignment seat, the fifth spring is located between the alignment arm and the alignment seat, the bearing is located at one end of the alignment arm and directly opposite the turntable, and is rotatably connected to the alignment arm. The adjusting bolt is located at the other end of the alignment arm and passes through the alignment seat, and is threadedly connected to the alignment seat. When the turntable drives the carrier to rotate, the pull head contacts the bearing, causing the alignment arm to be deflected by force. The fifth spring is compressed and reacts to the alignment arm, which in turn reacts to the pull head through the bearing, thereby adjusting the insertion depth of the pull head into the positioning tongue and the nylon tongue to achieve alignment.

[0010] Furthermore, the feeding mechanism includes a feeding track, a second cylinder, a sliding seat, a pressure arm, a first tension spring, pusher teeth, a reset rod, a reset block, and a second tension spring. The two ends of the feeding track are connected to the feeding vibrating plate and the frame, respectively. The second cylinder is located outside the feeding track and on the upper part of the frame, and is bolted to the feeding track. The sliding seat is located at the lower end of the second cylinder and is bolted to it. The pressure arm is located at the lower end of the sliding seat. The pressure arm is rotatably connected to the sliding seat. The two ends of the first tension spring are respectively connected to the pressure arm and the pull-plate feeding track. The pusher tooth is located at the lower end of the pressure arm and is bolted to the pressure arm. The reset rod passes through the pusher tooth and is interference-fitted with it. The reset block is located at the lower end of the pull-plate feeding track and is rotatably connected to it. The two ends of the second tension spring are respectively connected to the reset block and the pull-plate feeding track. The reset block also has an upper guide surface, a lower guide surface, and a pressure... The pressing surface is in contact with the sheet feeding track. The upper and lower guide surfaces are parallel, and the angle formed by the lower guide surface and the pressing surface is an acute angle. The sheet vibrating plate continuously conveys the sheet through the feeding chamber of the sheet feeding track. The second cylinder pushes the sliding seat to slide. Due to the tension of the first tension spring, the pusher teeth connected to the pressure arm push the sheet in the sheet feeding track to slide out. During this process, the reset rod slides along the lower guide surface on the reset block until the reset rod separates from the pressing surface. After the reset block rotates, it is pulled by the second tension spring. When the pressing surface is aligned with the feeding track of the pull piece, the reset rod slides along the upper guide surface of the reset block when the second cylinder returns, thereby driving the pressure arm to rotate and disengage from the feeding track of the pull piece. At this time, the next pull piece slides down to the position of the previous pull piece under the action of gravity. Since the width of the front end of the pull piece is greater than the width of the rear end, when the reset rod falls back under the action of the tension of the first tension spring at the highest point of the upper guide surface, the pusher tooth inserts into the feeding track of the pull piece and contacts the two sides of the pull piece. Repeating the above process can realize continuous and fast feeding of the pull piece.

[0011] Furthermore, the aforementioned spring feeding mechanism includes a spring feeding track, a support, a third cylinder, a pressure rod, a fixing block, a support rail, a pressure plate, and a third tension spring. The two ends of the spring feeding track are connected to the spring vibrating plate and the frame, respectively. The support is located at the lower end of the spring feeding track and the upper end of the frame, and is bolted to both the spring feeding track and the frame. The third cylinder is located at the upper end of the spring feeding track and the upper end of the support, and is bolted to the support. The pressure rod is located at the lower end of the third cylinder and the upper end of the spring feeding track, and is bolted to the third cylinder. The fixing block is located at the upper end of the support and the end of the spring feeding track, and is bolted to the support. The system is bolted together. The support rail is located on the upper end of the fixed block and is rotatably connected to the fixed block. The pressure plate is located on top of the fixed block and the support rail and is connected to the fixed block by bolts. The two ends of the third tension spring are respectively connected to the support rail and the support. The spring vibrating plate continuously conveys the spring through the feeding chamber of the spring feeding mechanism. When the spring is conveyed along the support rail to the pressure plate, the pressure plate hinders the further conveying of the spring. The third cylinder pushes the pressure rod downward to push the spring. The support rail rotates under force, thereby accurately pushing the spring onto the pull plate and pull head on the carrier. During this process, the third tension spring deforms under force. When the third cylinder returns and drives the pressure rod to return, the third tension spring resets and drives the support rail to reset. Repeating the above steps can achieve continuous and accurate conveying of the spring.

[0012] Furthermore, the first material pulling mechanism includes a guide seat, a fourth cylinder, a guide block, a fifth cylinder, a pull rod, and a material trough. The guide seat is located on the upper end of the frame. The fourth cylinder is installed on the left side of the guide seat. The guide block slides along the left and right direction of the guide seat and is connected to the fourth cylinder. The fifth cylinder is located on the right side of the guide block and is connected to the guide block by bolts. The pull rod slides along the up and down direction of the guide block and is connected to the fifth cylinder. The material trough is located on the right side of the guide seat and at the lower end of the pull rod. The material trough is connected to the guide seat by bolts. The fourth cylinder pushes the guide block to slide along the guide seat, causing the pull rod to move directly above the carrier. The fifth cylinder causes the pull rod to move down and catch the good or defective product. As the fourth cylinder returns, the good or defective product is pulled into the material trough.

[0013] Furthermore, the clamping mechanism includes a base, a side limiting plate, a wedge-shaped pusher, a side-pressure wedge block, a clamping assembly, a spring seat, a backstop groove, a sixth spring, a seventh spring, and a first pressing surface. The base is fixed to the upper end of the frame, the side limiting plate is installed on the left side of the base, the wedge-shaped pusher penetrates the base and is located on the right side of the side limiting plate, the wedge-shaped pusher slides along the vertical direction of the base and is connected to the slider by bolts, there are two side-pressure wedge blocks, symmetrically arranged along the front-rear direction of the base, the side-pressure wedge blocks are in close contact with the wedge-shaped pusher and slide along the left-right direction of the base, the clamping assembly is located between the two symmetrically arranged side-pressure wedge blocks, the clamping assembly is in close contact with the wedge-shaped pusher and slides along the left-right direction of the base, and the spring seat is located on the wedge-shaped pusher. The push head is mounted on the right side of the base. The anti-reverse groove runs through the main body of the wedge-shaped push head from top to bottom. The axis of the anti-reverse groove is perpendicular to the axis of the clamping assembly. The sixth spring is located between the spring seat and the side pressure wedge block. The seventh spring is located between the clamping assembly and the spring seat. The side pressure wedge block is provided with a first pressing surface, which is opposite to the clamping assembly. The drive mechanism drives the wedge-shaped push head to reciprocate. When the wedge-shaped push head moves down, it pushes the side pressure wedge block and the positive pressure wedge block that are in contact with the wedge-shaped push head to slide along the left and right directions of the base. Due to the two-stage movement mode of the positive pressure wedge block in the clamping assembly, the side pressure wedge block pushes the two clamps in the clamping assembly to close the mold during the movement, thereby clamping the pull head. The anti-reverse groove runs through the wedge-shaped pusher, so there are two surfaces opposite the wedge-shaped pusher and the clamping assembly. By designing different angles, the clamping assembly can be pushed into two different motion modes during the downward movement of the wedge-shaped pusher, thereby driving the clamping assembly to perform clamping operations on the pull head. The clamping assembly has two motion modes: an initial state and a clamping state. In the initial state, the positive pressure wedge block and the side pressure wedge block move in the same way, both moving the same displacement along the base. In the clamping state, the positive pressure wedge block and the anti-reverse groove are in contact under the action of the seventh spring. At this time, the positive pressure wedge block is stationary, but the side pressure wedge block continues to slide along the base. Therefore, the first extrusion surface pushes the second extrusion surface that cooperates with it, causing the two clamps to close and clamp the pull head. When the wedge-shaped pusher moves upward, the eighth spring returns to its original position, pushing the two clamps to separate, thus preparing for the next clamping operation.

[0014] Compared with existing technologies, this automatic zipper head assembly equipment, during operation, places the zipper head, zipper tab, and spring tab in the zipper head vibratory feeder, zipper tab vibratory feeder, and spring tab vibratory feeder, respectively. The zipper head is first continuously fed by the zipper head vibratory feeder to the zipper head feeding track within the zipper head feeding mechanism, and then guided by the guide section to the baffle groove. The first cylinder drives the pusher head to transport the zipper head into the carrier. The positioning tongue and nylon tongue within the carrier work together to insert into the zipper head's inner cavity and clamp it. Subsequently, the drive mechanism drives the turntable to rotate the carrier to the position corresponding to the zipper tab feeding mechanism. During this process, the bearing in the alignment mechanism contacts the zipper head to align it. The zipper tab is continuously fed into the carrier by the zipper tab feeding mechanism under the vibration of the zipper tab vibratory feeder. The steel balls within the carrier... The pull tab is positioned and clamped. With the continuous operation of the drive mechanism, the carrier is transported to directly below the spring sheet feeding mechanism. The spring sheet vibratory feeder continuously feeds the spring sheets to the spring sheet feeding mechanism, which gently presses the spring sheets onto the zipper head and the upper end of the pull tab. Finally, it is conveyed to the clamping mechanism. With the cooperation of the pressing components within the detection pressing mechanism, the zipper head is clamped and deformed, completing the fixing of the spring sheet. During the above process, the detection pressing mechanism rotates once at equal intervals with the turntable, completing one pressing test. The upward movement of the detection needle rod triggers the fiber optic sensor to determine if there is an assembly defect. If the fiber optic sensor is not triggered by the detection needle rod, the first pulling mechanism pulls the defective product out of the carrier; if it is qualified, the second pulling mechanism pulls the qualified product out of the carrier, realizing automatic zipper assembly. This device has a simple structure, can automatically complete zipper assembly, has extremely high production efficiency, and integrates detection functions, greatly improving the product qualification rate.

The connecting arm 218 is penetrated by the first rotating pin 217, and the connecting arm 218 is connected to the first rotating pin 217 with a clearance fit. The second rotating pin 219 penetrates the connecting arm 218, and the second rotating pin 219 is connected to the connecting arm 218 with a clearance fit. The connecting disc 216 is fixed on the fixing sleeve of the divider 203. The guide rod 215, which is fixed to the connecting disc 216, is used to maintain the stability of the movement of the pressing mechanism 5. The motor 201 drives the rotating shaft 204 to rotate through the belt drive mechanism 206. The rotating shaft 204 can simultaneously drive the connecting disc 216 and the drive gear 210 in the right eccentric assembly 207 and the left eccentric assembly 212 to rotate. When the right eccentric assembly 207 is working...The connecting plate 216 drives the connecting arm 218 to rotate via the eccentric first rotating pin 217, which in turn drives the slider 209 to slide along the vertical direction of the frame via the connecting rod 208. This, in turn, drives the wedge-shaped push head 1403 inside the clamping mechanism 14 to slide vertically. When the left eccentric component 212 rotates, the connecting plate 216 drives the connecting arm 218 to rotate via the eccentric first rotating pin 217, which in turn drives the support shaft 213 to move vertically along the guide rod 215 via the detection plate 501. However, when the driving gear 210 drives the driven gear 211 to rotate, the drive divider 203 drives the carrier 4 on the turntable 3 to move, thus enabling it to move to different work positions for corresponding operations. The above movements are linked, that is, when the divider 203 rotates one position at equal intervals, the right eccentric component 207 and the left eccentric component 212 respectively drive the clamping mechanism 14 and the detection pressing mechanism 5 to reciprocate once.

[0018] like Figure 7As shown, the carrier 4 includes a carrier base 401, a third rotating pin 402, a rocker block 403, a positioning block 404, a first spring 405, a first limiting groove 406, a steel ball 407, an adjusting screw 408, a second spring 409, a positioning tongue 410, and a nylon tongue 411. The carrier base 401 is fixed to the upper end of the turntable 3. The third rotating pin 402 passes through the carrier base 401. The rocker block 403 is located at the upper end of the carrier base 401 and is passed through by the third rotating pin 402. The rocker block 403 and the third rotating pin 404... The 02 clearance fit is used to connect the positioning block 404 between the rocker block 403 and the carrier seat 401. The positioning block 404 is connected to the carrier seat 401. The first spring 405 passes through the positioning block 404 and is located between the rocker block 403 and the carrier seat 401. The first limiting groove 406 is formed on one side of the positioning block 404. The steel ball 407 is placed in the first limiting groove 406. The adjusting screw 408 is fixed to the upper end of the first limiting groove 406. The second spring 409 is located at the adjusting screw 408. Between 08 and steel ball 407, the positioning tongue 410 is located to the right of the positioning block 404. The positioning tongue 410 is integrally connected to the positioning block 404. The nylon tongue 411 is located at the top of the positioning tongue 410. When the first cylinder 702 drives the pusher head 703 to push the pull head, the positioning tongue 410 is directly opposite the cavity of the pull head. With the movement of the first cylinder 702, the positioning tongue 410 and the nylon tongue 411 are inserted into the pull head, thereby clamping and positioning the pull head. Due to the slight deformation inside the nylon tongue 411, on the one hand... The second cylinder 1002 drives the pressure arm 1004 to push the pusher tooth 1006 into the carrier 4. The rocker block 403 rotates slightly along the third rotating pin 402 to form a cavity with the puller to accommodate the puller. During this process, the steel ball 407 in the first limiting groove 406 is pushed upward by the force. The second spring 409 reacts to the steel ball to press the puller and the puller together lightly. The adjusting screw 408 can adjust the deformation of the second spring 409 to adjust the clamping effect.

[0019] like Figure 8 , Figure 9As shown, the detection pressing mechanism 5 includes a detection disc 501, a detection component 502, and a pressing component 503. The detection disc 501 is penetrated by a support shaft 213, and the detection disc 501 and the support shaft 213 are connected by bolts. The axis of the detection disc 501 coincides with the axis of the turntable 3. The detection component 502 includes a first clamp 504, a detection needle bar 505, a third spring 506, and a fiber optic sensor 507. The first clamp 504 is disposed at the edge of the detection disc 501, and the detection needle bar 506... The third spring 506 slides along the vertical direction of the first clamp 504, and is located at the lower end of the first clamp 504 and outside the detection needle bar 505. The fiber optic sensor 507 is disposed on the top of the first clamp 504. The pressing assembly 503 includes a second clamp 508, a pressing die 509, and a fourth spring 510. The second clamp 508 is disposed at the edge of the detection plate 501. The pressing die 509 slides along the vertical direction of the second clamp 508. The fourth spring 510 is located at the edge of the pressing die 508. 9 is located at the upper end and inside the second clamp 508. The detection plate 501 moves downward with the support shaft 213. When the detection needle bar 505 detects that the pull tab and pull head are in the normal installation position, the detection needle bar 505 moves upward to trigger the fiber optic sensor 507. The control system records this station as a good product station. When the transfer is completed, the good product is pulled out by the second pulling mechanism 15. However, when the pull tab and pull head are in the abnormal installation position, the detection needle bar 505 cannot trigger the fiber optic sensor 507. The control system records this station as a defective product station and does not perform subsequent processes. In the process, the defective workpiece is pulled out by the first pulling mechanism 13. By setting multiple sets of detection components 502, such as after the pull head, pull tab, and spring are loaded into the carrier 4, the detection components 501 can be set to ensure the assembly yield to a greater extent. The pressing die head 509 moves down with the support shaft 213 and contacts the pull head, pull tab, and spring that have been aligned but not pressed. The fourth spring 510 deforms and lightly presses the aligned but not pressed pull head, pull tab, and spring. In conjunction with the clamping mechanism 14, the contact surface of the pull head and the spring is engaged and deformed, thereby completing the assembly.

[0020] like Figure 10 , Figure 11As shown, the pull head feeding mechanism 7 includes a pull head feeding track 701, a first cylinder 702, and a push head 703. The pull head feeding track 701 is located outside the pull head vibrating plate 6. The first cylinder 702 is located at the bottom of the pull head feeding track 701. The push head 703 is connected to the first cylinder 702 and is directly opposite the turntable 3. The push head 703 is also provided with a baffle groove 704 and a guide part 705. The baffle groove 704 is located at the right end of the push head 703 and penetrates through the push head. 703, the guide part 705 is located at the left end of the baffle groove 704, and the angle between the guide part 705 and the horizontal plane is an acute angle. The pull head vibrating plate 6 continuously feeds material to the pull head feeding track 701 inside the pull head feeding mechanism 7, and under the guidance of the guide part 705, it is transported to the baffle groove 704. The first cylinder 702 drives the push head 703 to transport the pull head into the carrier 4. Due to the limiting effect of the baffle groove 704, the positioning tongue 410 and the nylon tongue 411 inside the carrier 4 are inserted into the cavity at the tail of the pull head, thereby completing the feeding of the pull head.

[0021] like Figure 12 As shown, the alignment mechanism 8 includes an alignment seat 801, an alignment arm 802, a fifth spring 803, a bearing 804, and an adjusting bolt 805. The alignment seat 801 is disposed on the upper end of the frame 1. The alignment arm 802 is rotatably connected to the alignment seat 801. The fifth spring 803 is located between the alignment arm 802 and the alignment seat 801. The bearing 804 is located at one end of the alignment arm 802 and is directly opposite the turntable 3. The bearing 804 is rotatably connected to the alignment arm 802. The adjusting bolt 805 is located at the other end of the alignment arm 802 and passes through the alignment seat 801. The adjusting bolt 805 is threadedly connected to the alignment seat 801. When the turntable 3 drives the carrier 4 to rotate, the pull head contacts the bearing 804, causing the alignment arm 802 to be deflected by force. The fifth spring 803 is compressed and reacts to the alignment arm 802, and then reacts to the pull head through the bearing 804. This allows the depth of the pull head inserted into the positioning tongue 410 and the nylon tongue 411 to be adjusted, thus achieving alignment.

[0022] like Figure 13 , Figure 14 , Figure 15As shown, the feeding mechanism 10 includes a feeding track 1001, a second cylinder 1002, a sliding seat 1003, a pressure arm 1004, a first tension spring 1005, a pushing tooth 1006, a reset rod 1007, a reset block 1008, and a second tension spring 1009. The two ends of the feeding track 1001 are connected to the feeding vibrating plate 9 and the frame 1, respectively. The second cylinder 1002 is located outside the feeding track 1001 and on the upper end of the frame 1. The second cylinder 1002 is bolted to the feeding track 1001. The sliding seat 1003 is located below the second cylinder 1002 and bolted to the second cylinder 1002. The pressure arm 1004... 4. Located at the lower end of the sliding seat 1003, the pressure arm 1004 is rotatably connected to the sliding seat 1003. The two ends of the first tension spring 1005 are respectively connected to the pressure arm 1004 and the pull-piece feeding track 1001. The pusher tooth 1006 is located at the lower end of the pressure arm 1004 and is bolted to the pressure arm 1004. The reset rod 1007 passes through the pusher tooth 1006 and is interference-fitted with the pusher tooth 1006. The reset block 1007 is located at the lower end of the pull-piece feeding track 1001 and is rotatably connected to the pull-piece feeding track 1001. The two ends of the second tension spring 1009 are respectively connected to the reset block 1007 and the pull-piece feeding track 1001. The reset block 1008 is further provided with an upper guide surface 1010, a lower guide surface 1011, and a pressing surface 1012. The pressing surface 1012 is in contact with the pull-piece feeding track 1001. The upper guide surface 1010 is located at the upper end of the reset block 1008. The upper guide surface 1010 and the lower guide surface 1011 are parallel. The angle formed by the lower guide surface 1011 and the pressing surface 1012 is an acute angle. The pull-piece vibrating disk 9 continuously conveys the pull-piece through the feeding chamber of the pull-piece feeding track 1001. The second cylinder 1002 pushes the sliding seat 1003 to slide. Due to the pulling force of the first tension spring 1005, the pusher tooth 1006 connected to the pressure arm 1004 pushes the pull-piece in the pull-piece feeding track 1001 to slide out. During this process, The reset rod 1007 slides along the lower guide surface 1010 on the reset block 1008 until it separates from the pressing surface 1012. After the reset block 1008 rotates, under the tension of the second tension spring 1009, it brings the pressing surface 1012 into contact with the pull plate feeding track 1001. When the second cylinder 1002 returns, the reset rod 1007 slides along the upper guide surface 1010 of the reset block 1008, thereby driving the pressure arm 1004 to rotate and disengage from the pull plate feeding track 1001. At this time, the next pull plate slides down to the position of the previous pull plate under the action of gravity. Since the width of the front end of the pull plate is greater than the width of the rear end, when the reset rod 1007 falls back at the highest point of the upper guide surface 1010 under the tension of the first tension spring 1005,The pusher tooth 1006 inserts into the feed track 1001 and contacts both sides of the pull sheet. Repeating this process enables continuous and rapid feeding of the pull sheet.

[0023] like Figure 16 , Figure 17 As shown, the spring feeding mechanism 12 includes a spring feeding track 1201, a support 1202, a third cylinder 1203, a pressure rod 1204, a fixing block 1205, a support rail 1206, a pressure plate 1207, and a third tension spring 1208. The two ends of the spring feeding track 1201 are connected to the spring vibrating plate 11 and the frame 1, respectively. The support 1202 is located at the lower end of the spring feeding track 1201 and the upper end of the frame 1. The support 1202 is connected to the spring feeding track 1201 and the frame 1 by screws. The third cylinder 1203 is located at the upper end of the sheet feeding track 1201 and the upper end of the support 1202. The third cylinder 1203 and the support 1202 are connected by bolts. The pressure rod 1204 is located at the lower end of the third cylinder 1203 and the upper end of the sheet feeding track 1201. The pressure rod 1204 and the third cylinder 1203 are connected by bolts. The fixing block 1205 is located at the upper end of the support 1202 and the end of the sheet feeding track 1201. The fixing block 1205... 5 is connected to the support 1202 by bolts. The rail 1206 is located on the upper end of the fixed block 1205. The rail 1206 is rotatably connected to the fixed block 1205. The pressure plate 1207 is located on the top of the fixed block 1205 and the rail 1206. The pressure plate 1207 is connected to the fixed block 1205 by bolts. The two ends of the third tension spring 1208 are respectively connected to the rail 1206 and the support 1202. The spring vibrating plate 11 continuously conveys the spring through the feeding chamber of the spring feeding mechanism 12. When the spring moves along the rail... When 1206 is conveyed to the pressure plate 1207, the pressure plate 1207 obstructs the continued conveying of the spring sheet. The third cylinder 1203 pushes the pressure rod 1204 downward to press the spring sheet. The support rail 1206 rotates under force, thereby accurately pushing the spring sheet onto the pull plate and pull head on the carrier 4. During this process, the third tension spring 1208 deforms under force. When the third cylinder 1203 returns and drives the pressure rod 1204 to return, the third tension spring 1208 resets and drives the support rail 1206 to reset. By repeating the above steps, the continuous and accurate conveying of the spring sheet can be achieved.

[0024] like Figure 18As shown, the first material pulling mechanism 13 includes a guide seat 1301, a fourth cylinder 1302, a guide block 1303, a fifth cylinder 1304, a pull rod 1305, and a material trough 1306. The guide seat 1301 is located on the upper end of the frame 1. The fourth cylinder 1302 is installed on the left side of the guide seat 1301. The guide block 1303 slides along the left and right direction of the guide seat 1301 and is connected to the fourth cylinder 1302. The fifth cylinder 1304 is located on the right side of the guide block 1303. The fifth cylinder 1304 is connected to the guide block 1303 by bolts. The pull rod 1305 slides along the guide block 1303 in the vertical direction and is connected to the fifth cylinder 1304. The material trough 1306 is located on the right side of the guide seat 1301 and at the lower end of the pull rod 1305. The material trough 1306 is connected to the guide seat 1301 by bolts. The fourth cylinder 1302 pushes the guide block 1303 to slide along the guide seat 1301, driving the pull rod 1305 to move directly above the carrier 4. The fifth cylinder 1304 drives the pull rod 1305 to move down and catch the good or defective product. As the fourth cylinder 1302 returns, the good or defective product is pulled into the material trough 1306.

[0025] like Figure 19 , Figure 20As shown, the clamping mechanism 14 includes a base 1401, a side limiting plate 1402, a wedge-shaped pusher 1403, a side-pressure wedge block 1404, a clamping assembly 1405, a spring seat 1406, a backstop groove 1407, a sixth spring 1408, a seventh spring 1409, and a first pressing surface 1410. The base 1401 is fixed to the upper end of the frame 1. The side limiting plate 1402 is installed on the left side of the base 1401. The wedge-shaped pusher 1403 penetrates the base 1401 and is located on the right side of the side limiting plate 1402. The wedge-shaped pusher 1403 slides along the vertical direction of the base 1401 and is connected to the slider 209 by bolts. There are two side-pressure wedge blocks 1404, which are arranged along the base 1401. The base 1401 is symmetrically arranged in the front-back direction. The side-pressure wedge block 1404 is in close contact with the wedge push head 1403 and slides along the left-right direction of the base 1401. The clamping assembly 1405 is located between the two symmetrically arranged side-pressure wedge blocks 1404. The clamping assembly 1405 is in close contact with the wedge push head 1403 and slides along the left-right direction of the base 1401. The spring seat 1406 is located on the right side of the wedge push head 1403 and is installed on the top of the base 1401. The anti-reverse groove 1407 penetrates the body of the wedge push head 1403 from top to bottom. The axis of the anti-reverse groove 1407 is perpendicular to the axis of the clamping assembly 1405. The sixth spring 1408 is disposed between the spring seat 1406 and the side-pressure wedge block 1404. The seventh spring 1409 is disposed between the clamping assembly 1405 and the spring seat 1406. The side-pressure wedge block 1404 is provided with a first pressing surface 1410, which is opposite to the clamping assembly 1405. The clamping assembly 1405 includes a positive pressure wedge block 1411, a chuck 1412, a second pressing surface 1413, and an eighth spring 1414. The positive pressure wedge block 1411 is in close contact with the wedge push head 1403 and slides along the left and right direction of the base 1401. There are two chucks 1412, which are symmetrically arranged along the front and back direction of the positive pressure wedge block 1411. The chucks 1412 are rotatably connected to the positive pressure wedge block 1411. The chucks 1412 are also provided with... There is a second extrusion surface 1413, which is in contact with the first extrusion surface 1410. The eighth spring 1414 is disposed between two symmetrically arranged clamps 1412. The drive mechanism 2 drives the wedge push head 1403 to reciprocate. When the wedge push head 1403 moves down, the wedge push head 1403 pushes the side pressure wedge block 1404 and the positive pressure wedge block 1411 that are in contact with the wedge push head 1403 to slide along the left and right directions of the base 1401. Due to the two-stage movement mode of the positive pressure wedge block 1411 in the clamping assembly 1405, the side pressure wedge block 1404 pushes the two clamps 1412 in the clamping assembly 1405 to close the mold during the movement, thereby clamping the pull head.The anti-reverse groove 1407 penetrates the wedge-shaped pusher 1403. Therefore, the wedge-shaped pusher 1403 has two opposing surfaces with the clamping assembly 1405. By designing different angles, the clamping assembly 1405 can be pushed to form two different motion modes during the downward movement of the wedge-shaped pusher 1403, thereby driving the clamping assembly 1405 to perform clamping operations on the pull head. The clamping assembly 1405 has two motion modes: an initial state and a clamping state. In the initial state, the positive pressure wedge block 1411 and the side pressure wedge block 1404 move in the same way, both along the base 1. 401 moves by the same displacement; in the clamping state, the positive pressure wedge block 1412 and the anti-reverse groove 1407 are in contact under the action of the seventh spring 1409. At this time, the positive pressure wedge block 1411 is stationary, but the side pressure wedge block 1404 continues to slide along the base 1. Therefore, the first extrusion surface 1410 pushes the second extrusion surface 1413 that cooperates with it to drive the two clamps 1412 to close the mold and clamp the pull head. When the wedge push head 1403 moves up, the eighth spring 1414 resets and pushes the two clamps 1412 to separate, thus preparing for the next clamping.

[0026] In operation, the automatic zipper head assembly equipment places the zipper head, zipper tab, and spring tab into the zipper head vibrating plate 6, zipper tab vibrating plate 9, and spring tab vibrating plate 11, respectively. The zipper head is first continuously fed by the zipper head vibrating plate 6 to the zipper head feeding track 701 within the zipper head feeding mechanism 7, and then guided by the guide section 705 to the baffle groove 704. The first cylinder 702 drives the pusher head 703 to transport the zipper head into the carrier 4. The positioning tongue 410 and nylon tongue 411 within the carrier 4 work together to insert into the zipper head's inner cavity and clamp it. Subsequently, the drive mechanism 2 drives the turntable 3 to rotate the carrier 4 to the position directly opposite the zipper tab feeding mechanism 10. During this process, the bearing 804 within the alignment mechanism 8 contacts the zipper head to align it. The zipper tab is continuously fed into the carrier 4 via the zipper tab feeding mechanism 10 under the vibration of the zipper tab vibrating plate 9. The steel ball 40 within the carrier 4... 7. Position and clamp the pull tab. As the drive mechanism 2 works continuously, the carrier 4 is transported to the area directly below the spring sheet feeding mechanism 12. The spring sheet vibrating plate 11 continuously feeds the spring sheet to the spring sheet feeding mechanism 12. The spring sheet feeding mechanism 12 gently presses the spring sheet onto the pull head and the upper end of the pull tab. Finally, it is transported to the clamping mechanism 14. With the cooperation of the pressing component 503 in the detection pressing mechanism 5, the pull head is clamped and deformed to fix the spring sheet. During the above process, the detection pressing mechanism 5 rotates once at equal intervals with the turntable 3 to complete one pressing test. The upward movement of the detection needle rod 505 triggers the fiber optic sensor 507 to determine whether there is a poor assembly. If the fiber optic sensor 507 is not triggered by the detection needle rod 505, the first pulling mechanism 13 pulls the defective product out of the carrier 4. If it is qualified, the second pulling mechanism 15 pulls the qualified product out of the carrier 4, realizing the automatic assembly of the zipper. This device has a simple structure and can automatically complete the assembly of zippers, resulting in extremely high production efficiency. It also integrates detection functions, which greatly improves the product qualification rate.

[0027] This invention is not limited to the specific embodiments described above. Any modifications made by those skilled in the art based on the above concept without creative effort are within the scope of protection of this invention.
