Description

Technical Field

[0001] This utility model relates to the technical field of emulsion pump assembly equipment, and in particular to an automatic emulsion pump feeding and assembly machine. Background Technology

[0002] An emulsion pump is a device that pumps emulsion out of a bottle, such as... Figure 1 As shown, structurally, the emulsion pump mainly includes an annular gasket, pump body, glass beads, return spring, piston assembly, threaded cap, and neck ring.

[0003] Most existing emulsion pump assembly machines use either square chain plate transmission or round turntable transmission.

[0004] However, due to the differences in the parts of various types of emulsion pumps, such as annular gaskets, if the diameter is large and the annular area is small, such gaskets are prone to deformation and are difficult to position. This usually results in a decrease in yield and production capacity during the assembly process. In this case, the annular gaskets need to be pre-assembled, and the degree of automation in production is low. Utility Model Content

[0005] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes an automatic emulsion pump assembly machine, which can facilitate the positioning of the annular gasket, eliminate the need for pre-assembly of the annular gasket, and improve the degree of automation in assembly.

[0006] According to an embodiment of the present utility model, an automatic emulsion pump feeding and assembly machine includes a turntable, a tooling seat disposed on the turntable, and a gasket feeding mechanism, a pump body feeding mechanism, a glass bead feeding mechanism, a spring feeding mechanism, a piston assembly feeding mechanism, a piston assembly punching mechanism, a threaded cap feeding mechanism, a neck ring feeding mechanism, and a neck ring punching mechanism disposed on the radially outer side of the turntable and arranged sequentially along the rotation direction of the turntable. The tooling base is used to place the parts of the emulsion pump. The top of the tooling base is provided with a positioning groove, which accommodates an annular gasket. The side wall of the positioning groove is used to limit the outer circular wall of the annular gasket. The gasket feeding mechanism is used to transport the annular gasket to the positioning groove. The gasket feeding mechanism includes a first mechanical clamp, which tensions the inner circular wall of the annular gasket to grip the annular gasket.

[0007] The automatic emulsion pump feeding and assembly machine according to the embodiments of the present invention has at least the following beneficial effects: 1. This utility model uses a turntable to move a tooling seat around a circular path. Simultaneously, on the radially outer side of the turntable and along its rotation direction, a gasket feeding mechanism, a pump body feeding mechanism, a glass bead feeding mechanism, a spring feeding mechanism, a piston assembly feeding mechanism, a piston assembly punching mechanism, a threaded cap feeding mechanism, a neck ring feeding mechanism, and a neck ring punching mechanism are sequentially arranged. It can be understood that the gasket feeding mechanism is used to transport the annular gasket to the tooling seat; the pump body feeding mechanism is used to transport the pump body to the tooling seat and embed the pump body into the inner side of the annular gasket on the tooling seat; the glass bead feeding mechanism is used to transport the glass beads into the pump body on the tooling seat; and the spring feeding mechanism is used to transport the return spring into the pump body on the tooling seat. The piston assembly feeding mechanism is used to transport the piston assembly to the pump body on the tooling seat. The piston assembly punching mechanism is used to press the piston assembly to the pump body. The threaded cap is used to transport the threaded cap to the pump body on the tooling seat. The neck ring feeding mechanism is used to transport the neck ring to the piston assembly on the tooling seat. The neck ring punching mechanism is used to press the neck ring to the pump body. Thus, the turntable can drive the tooling seat to pass through the gasket feeding mechanism, pump body feeding mechanism, glass bead feeding mechanism, spring feeding mechanism, piston assembly feeding mechanism, piston assembly punching mechanism, threaded cap feeding mechanism, neck ring feeding mechanism, and neck ring punching mechanism in sequence. This integrates multiple assembly processes of the emulsion pump, eliminates the manual pre-assembly required in traditional equipment, and significantly improves production efficiency and yield.

[0008] 2. This utility model features a positioning groove on the top of the tooling base. The positioning groove accommodates an annular gasket, and the sidewall of the positioning groove limits the outer circular wall of the annular gasket. A gasket feeding mechanism transports the annular gasket to the positioning groove. The gasket feeding mechanism includes a first mechanical clamp that tensions the inner circular wall of the annular gasket to grip it. It can be understood that the positioning groove's sidewall limiting the outer circular wall of the annular gasket and the first mechanical clamp's tensioning of the inner circular wall of the annular gasket form a dual positioning system for the annular gasket, reducing the risk of annular gasket deformation, improving assembly accuracy, reducing the assembly defect rate caused by annular gasket deformation during assembly, eliminating the need for pre-assembly of the annular gasket, and improving the degree of assembly automation.

[0009] 3. This utility model, by using the clamping method of tensioning the inner circular wall of the annular gasket with the first mechanical clamp, can avoid the compression and deformation of the thin-walled gasket caused by the traditional external clamp, thereby reducing assembly defects from the source.

[0010] According to some embodiments of the present invention, the opening of the positioning groove is provided with a guide bevel.

[0011] The advantage of this invention is that by setting a guide angle at the opening of the positioning groove, the guide angle can guide the annular gasket to smoothly enter the positioning groove, preventing the annular gasket from getting stuck or curling due to positional deviation when the first mechanical clamp is placed, thereby further reducing the assembly failure rate.

[0012] According to some embodiments of the present invention, the bottom wall of the positioning groove is provided with a supporting protrusion ring, which is used to support the bottom surface of the annular gasket near the inner side.

[0013] The advantages of this invention are: by providing a supporting protrusion ring on the bottom wall of the positioning groove, the supporting protrusion ring is used to support the bottom surface of the annular gasket near the inner side. It can be understood that when the pump body is embedded in the inner side of the annular gasket, the main stress position of the annular gasket is on the inner side wall of the annular gasket. In view of the problem of uneven stress on the annular gasket when the pump body is embedded in the inner side of the annular gasket, the supporting protrusion ring can provide local support force to the bottom surface of the inner side of the annular gasket, ensuring that the annular gasket remains horizontal when the pump body is embedded, and avoiding the problem of deformation of the annular gasket due to uneven stress.

[0014] According to some embodiments of the present invention, the tooling base includes a supporting cylinder, a positioning seat sleeved on the supporting cylinder and slidably connected to the supporting cylinder up and down, and a first spring. The positioning groove is disposed on the positioning seat, and the first spring is used to drive the positioning seat to rise and reset.

[0015] The advantages of this invention are: the tooling base includes a supporting cylinder, a positioning seat sleeved on the outside of the supporting cylinder and slidably connected to the supporting cylinder, and a first spring. The positioning groove is set on the positioning seat, and the first spring is used to drive the positioning seat to rise and reset. It can be understood that the positioning seat is slidably connected to the supporting cylinder through the first spring, so as to realize the adaptive adjustment of the tooling base height.

[0016] According to some embodiments of the present invention, the bottom wall of the positioning groove is provided with a clearance hole that passes through the positioning seat from top to bottom. The clearance hole is used to avoid the support cylinder. When the pump body is embedded in the inner side of the annular gasket, the pump body squeezes the positioning seat down. The top of the support cylinder can support the bottom surface of the annular gasket so that the pump body can be embedded in the annular gasket.

[0017] The advantages of this invention are: by providing a clearance hole through the positioning seat on the bottom wall of the positioning groove, the clearance hole is used to avoid the support cylinder. When the pump body is embedded in the inner side of the annular gasket, the pump body presses the positioning seat down, and the top of the support cylinder can support the bottom surface of the annular gasket so that the pump body can be embedded in the annular gasket. It can be understood that when the pump body is embedded in the annular gasket, the pump body presses down on the positioning seat, and the top of the support cylinder lifts the bottom surface of the annular gasket, avoiding a hard collision between the pump body and the annular gasket and protecting easily deformable parts.

[0018] According to some embodiments of the present invention, the first spring is sleeved on the outside of the supporting cylinder, and the outer wall of the supporting cylinder is provided with an outer protruding ring. The outer protruding ring abuts against the lower end of the first spring, and the upper end of the first spring abuts against the bottom wall of the positioning seat.

[0019] The advantages of this invention are: by sleeved a first spring on the outside of the supporting cylinder, and provided with an outer protruding ring on the outer wall of the supporting cylinder, the outer protruding ring abuts against the lower end of the first spring, and the upper end of the first spring abuts against the bottom wall of the positioning seat, it can be understood that the first spring is sleeved on the outside of the supporting cylinder and limited by the outer protruding ring, resulting in a compact structure and providing a stable restoring elastic force.

[0020] According to some embodiments of the present invention, the outer wall of the supporting cylinder is provided with a guide groove extending vertically, and the positioning seat is provided with a guide pin, which cooperates with the guide groove for guidance.

[0021] The advantages of this invention are: by providing a vertically extending guide groove on the outer wall of the supporting cylinder and a guide pin on the positioning seat, the guide pin and the guide groove cooperate to guide the positioning seat. It can be understood that the cooperation between the guide groove and the guide pin ensures that the positioning seat can be raised and lowered vertically without deflection, and maintains the positional accuracy of the annular gasket.

[0022] According to some embodiments of this utility model, the spring feeding mechanism is used to transport the reset spring to the pump body on the tooling seat. The spring feeding mechanism includes a first guide seat, a second mechanical clamp, a flipping base plate, a first cylinder, and a second cylinder. The first guide seat is provided with a first guide channel extending vertically, through which reset springs stacked vertically pass. The flipping base plate is hinged to the bottom of the first guide seat and covers the bottom end of the first guide channel to support the reset spring in the first guide channel. The first cylinder and the second mechanical clamp are arranged vertically in the first guide channel, and the second mechanical clamp is used to clamp and transport the reset spring. A guide channel is located at the bottom of a return spring. The first cylinder is used to press a return spring above the second mechanical clamp to limit the return spring in the first wire channel. The second cylinder is set on the first guide seat. The output end of the second cylinder is provided with an abutment. The abutment is used to abut the flip base plate. The second cylinder is used to drive the flip base plate to flip and open the bottom end of the first guide channel so that the second mechanical clamp can transport the return spring from the first guide channel to the pump body on the tooling seat. A first torsion spring is provided between the flip base plate and the first guide seat. The first torsion spring is used to drive the flip base plate to flip and reset.

[0023] The advantages of this invention are that by arranging the first cylinder and the second mechanical clamp vertically in the first guide channel, when the second mechanical clamp holds the return spring at the bottom of the first guide channel, the first cylinder can press the upper return spring to prevent the upper return spring from falling off when the second mechanical clamp picks up the material. At the same time, the second cylinder drives the flipping base plate to open and close, ensuring that only one spring is released at a time, which, together with the first torsion spring, automatically resets the material, realizing high-speed intermittent feeding.

[0024] According to some embodiments of the present invention, the automatic emulsion pump feeding assembly machine further includes a gasket detection mechanism, which is located between the pump body feeding mechanism and the glass bead feeding mechanism. The gasket detection mechanism is used to detect whether the assembled product with the pump body mounted on the tooling base has an annular gasket.

[0025] The advantages are: by setting up a gasket detection mechanism, which is located between the pump body feeding mechanism and the glass bead feeding mechanism, this utility model can detect whether the assembled product with the pump body on the tooling seat has an annular gasket. It can be understood that by setting up a detection station after the pump body is fed and before the glass beads are assembled, semi-finished products with missing gaskets can be intercepted in advance, avoiding the waste of resources caused by subsequent ineffective assembly and directly reducing costs.

[0026] According to some embodiments of this utility model, the automatic emulsion pump feeding and assembly machine further includes a qualified product discharge mechanism and a defective product discharge mechanism. The qualified product discharge mechanism and the defective product discharge mechanism are located on the lower station side of the neck ring punching mechanism along the rotation direction of the turntable. The qualified product discharge mechanism is used to transfer the assembled and qualified emulsion pump for discharge, and the defective product discharge mechanism is used to transfer the unqualified semi-finished products and emulsion pump parts that fail the inspection during the assembly process for discharge.

[0027] The advantages of this invention are: by setting up a qualified product discharge mechanism and a defective product discharge mechanism, which are located on the lower station side of the neck ring punching mechanism along the rotation direction of the turntable, the qualified product discharge mechanism is used to transfer and discharge the assembled and qualified emulsion pumps, while the defective product discharge mechanism is used to transfer and discharge the semi-finished products and emulsion pump parts that fail the inspection during the assembly process. It can be understood that the qualified and defective products are discharged separately to avoid mixing materials and scrapping the entire batch. In addition, defective parts can be recycled and reused, reducing material loss and meeting the needs of lean production.

[0028] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0036] The following is in conjunction with the appendix Figure 1 - Appendix Figure 7 This invention describes an automatic emulsion pump feeding and assembly machine according to an embodiment of the present invention.

[0037] This invention aims to provide an embodiment of an automatic emulsion pump feeding and assembly machine.

[0038] For emulsion pumps, refer to Figure 1 The emulsion pump mainly includes an annular gasket 40, a pump body 41, a glass bead 42, a return spring 43, a piston assembly 44, a threaded cap 45, and a neck ring 46.

[0039] Reference Figure 2 and Figure 3 In this embodiment, the automatic emulsion pump feeding and assembly machine mainly includes a turntable 14, a tooling seat 13 disposed on the turntable 14, and a gasket feeding mechanism 1, a pump body feeding mechanism 2, a glass bead feeding mechanism 4, a spring feeding mechanism 5, a piston assembly feeding mechanism 6, a piston assembly punching mechanism 7, a threaded cap feeding mechanism 8, a neck ring feeding mechanism 9, and a neck ring punching mechanism 10 disposed on the radially outer side of the turntable 14 and arranged sequentially along the rotation direction of the turntable 14.

[0040] Understandably, the turntable 14 can drive the tooling seat 13 to pass through the gasket feeding mechanism 1, the pump body feeding mechanism 2, the glass bead feeding mechanism 4, the spring feeding mechanism 5, the piston assembly feeding mechanism 6, the piston assembly punching mechanism 7, the threaded cap feeding mechanism 8, the neck ring feeding mechanism 9, and the neck ring punching mechanism 10 in sequence, integrating multiple assembly processes of the emulsion pump, eliminating the manual pre-assembly required by traditional equipment, and significantly improving production efficiency and yield.

[0041] For the gasket feeding mechanism 1, the gasket feeding mechanism 1 is used to transport the annular gasket 40 onto the tooling seat 13.

[0042] Specifically, the gasket feeding mechanism 1 can include a first vibrating plate, which is used to sort the materials and push them one by one into the first material channel. The annular gaskets 40 are arranged in single pieces in the first material channel and positioned at the end of the first material channel. The annular gaskets 40 are tensioned inside by a first mechanical clamp, and the first mechanical clamp is driven to move the annular gaskets 40 out of the first material channel and send them to the tooling seat 13. After the first mechanical clamp is released, the annular gaskets 40 slide onto the tooling seat 13.

[0043] For the pump body feeding mechanism 2, the pump body feeding mechanism 2 is used to transport the pump body 41 to the tooling seat 13 and embed the pump body 41 into the inner side of the annular gasket 40 on the tooling seat 13.

[0044] Specifically, the pump body feeding mechanism 2 can use a second vibrating plate in conjunction with a second material channel for feeding. The pump body 41 is positioned at the end of the second material channel and clamped by a third mechanical clamp. A cylinder drives the third mechanical clamp to rise and remove the pump body 41. The cylinder moves forward so that the third mechanical clamp sends the pump body 41 above the tooling seat 13. The cylinder drives the third mechanical clamp to descend, and the pump body 41 passes through the annular gasket 40, releasing the third mechanical clamp. The pump body 41 slides into the tooling seat 13.

[0045] The glass bead feeding mechanism 4 is used to transport glass beads 42 into the pump body 41 on the tooling seat 13.

[0046] The spring feeding mechanism 5 is used to transport the return spring 43 into the pump body 41 on the tooling seat 13.

[0047] Reference Figure 4Specifically, the spring feeding mechanism 5 includes a first guide seat 31, a second mechanical clamp 36, a flipping base plate 34, a first cylinder 33, and a second cylinder 30. The first guide seat 31 is provided with a vertically extending first guide channel 32, which accommodates stacked reset springs 43. The flipping base plate 34 is hinged to the bottom of the first guide seat 31 and covers the bottom end of the first guide channel 32 to support the reset springs 43 inside the first guide channel 32. The first cylinder 33 and the second mechanical clamp 36 are arranged vertically in the first guide channel 32. The second mechanical clamp 36 is used to clamp and transport the lowest reset spring in the first guide channel 32. Spring 43, first cylinder 33 is used to press a reset spring 43 above the second mechanical clamp 36 to limit the reset spring 43 in the first wire channel. Second cylinder 30 is set on the first guide seat 31. The output end of the second cylinder 30 is provided with abutment 35, abutment 35 is used to abut against the flip base plate 34. Second cylinder 30 is used to drive the flip base plate 34 to flip open the bottom end of the first guide channel 32 so that the second mechanical clamp 36 can transport the reset spring 43 from the first guide channel 32 to the pump body 41 on the tooling seat 13. First torsion spring is provided between the flip base plate 34 and the first guide seat 31. First torsion spring is used to drive the flip base plate 34 to flip and reset.

[0048] In this embodiment, the first cylinder 33 and the second mechanical clamp 36 are arranged vertically in the first guide channel 32. Thus, when the second mechanical clamp 36 clamps the return spring 43 at the bottom of the first guide channel 32, the first cylinder 33 can press the upper return spring 43 to prevent the upper return spring 43 from falling off when the second mechanical clamp 36 picks up the material. At the same time, the second cylinder 30 drives the flipping base plate 34 to open and close, ensuring that only one spring is released at a time. With the automatic reset of the first torsion spring, high-speed intermittent feeding is achieved.

[0049] The piston assembly feeding mechanism 6 is used to transport the piston assembly 44 to the pump body 41 on the tooling seat 13.

[0050] Specifically, the piston assembly feeding mechanism 6 can use a third vibrating plate in conjunction with a third material channel for feeding, and then transport the piston assembly 44 to the pump body 41 in the same way as the spring feeding mechanism 5 described above. The structure of the piston assembly feeding mechanism 6 can be similar to that of the spring feeding mechanism 5 described above, and will not be described in detail here.

[0051] For the piston assembly punching mechanism 7, the piston assembly punching mechanism 7 is used to press the piston assembly 44 with the pump body 41 so that the end of the piston assembly 44 is perpendicular to the tooling seat 13.

[0052] Specifically, the piston assembly punching mechanism 7 can include a first punch and a first power component. The first power component drives the first punch to rise and fall, and the first punch descends to press the piston assembly 44.

[0053] The threaded cover feeding mechanism 8 is used to transport the threaded cover 45 to the pump body 41 on the tooling seat 13.

[0054] Specifically, the threaded tooth cover feeding mechanism 8 can use a fourth vibrating plate in conjunction with a fourth material channel for feeding. The end of the fourth material channel is contour-guided for positioning. The fourth mechanical clamp holds the threaded tooth cover 45 at the end of the fourth material channel. The cylinder drives the fourth mechanical clamp to lift and lower to move the threaded tooth cover 45 away from the fourth material channel. Then, the cylinder is driven to move back and forth to feed the material and place the threaded tooth cover 45 on the tooling seat 13.

[0055] The neck ring feeding mechanism 9 is used to transport the neck ring 46 onto the piston assembly 44 on the tooling seat 13.

[0056] Specifically, the neck ring feeding mechanism 9 can use a fifth vibrating plate in conjunction with a fifth material channel for feeding. The end of the fifth material channel is positioned by contouring. The fifth mechanical clamp holds the neck ring 46 at the end of the fifth material channel. The cylinder drives the fifth mechanical clamp to lift and lower to move the neck ring 46 away from the fifth material channel. Then, the cylinder is driven to move back and forth to feed the material, moving the neck ring 46 to the piston assembly 44 above the tooling seat 13. Next, the sixth mechanical clamp is used to clamp the piston assembly 44 to position it. The cylinder then drives the fifth mechanical clamp to lower to insert the neck ring 46 into the piston assembly 44.

[0057] The neck ring punching mechanism 10 is used to press the neck ring 46 onto the pump body 41.

[0058] Specifically, the neck ring punching mechanism 10 can include a second punch and a second power component. The second power component drives the second punch to rise and fall. The second punch descends to press the neck ring 46 onto the pump body 41. After pressing, the tooling seat 13 moves the pump body 41 upward to reset through the elastic reset action of the first spring 23.

[0059] In some specific embodiments, the neck ring punching mechanism 10 may also include an optical fiber sensor to detect the position of the emulsion pump in order to determine whether the emulsion pump has been assembled.

[0060] Reference Figure 5 , Figure 6 and Figure 7 For the tooling base 13, the tooling base 13 is used to place the parts of the emulsion pump. The top of the tooling base 13 is provided with a positioning groove 24, which accommodates the annular gasket 40. The side wall of the positioning groove 24 is used to limit the outer circular wall of the annular gasket 40. The gasket feeding mechanism 1 is used to transport the annular gasket 40 to the positioning groove 24. The gasket feeding mechanism 1 includes a first mechanical clamp, which tensions the inner circular wall of the annular gasket 40 to grip the annular gasket 40.

[0061] Understandably, the positioning groove 24 sidewall limits the outer circular wall of the annular gasket 40 and the first mechanical clamp tensions the inner circular wall of the annular gasket 40, forming a dual positioning of the annular gasket 40 inside and outside. This reduces the risk of deformation of the annular gasket 40, improves assembly accuracy, reduces the assembly defect rate caused by deformation of the annular gasket 40 during the assembly process, eliminates the need for pre-assembly of the annular gasket 40, and improves the degree of automation in assembly.

[0062] This embodiment avoids the compression and deformation of thin-walled gaskets caused by traditional external clamps by using the clamping method of tensioning the inner wall of the annular gasket 40 with the first mechanical clamp, thereby reducing assembly defects from the source.

[0063] In some specific embodiments, the groove opening of the positioning circular groove 24 is provided with a guide angle 25, so that the guide angle 25 can guide the annular gasket 40 to smoothly enter the positioning circular groove 24, preventing the annular gasket 40 from getting stuck or curling due to positional deviation when the first mechanical clamp is placed, and further reducing the assembly failure rate.

[0064] In some specific embodiments, the bottom wall of the positioning groove 24 is provided with a supporting protrusion 26, which is used to support the bottom surface of the annular gasket 40 near the inner side.

[0065] Understandably, when the pump body 41 is embedded inside the annular gasket 40, the main stress point of the annular gasket 40 is on the inner wall of the annular gasket 40. To address the issue of uneven stress on the annular gasket 40 when the pump body 41 is embedded inside the annular gasket 40, the supporting protrusion 26 can provide local support to the bottom surface of the inner side of the annular gasket 40, ensuring that the annular gasket 40 remains horizontal when the pump body 41 is embedded, thus avoiding the problem of deformation of the annular gasket 40 due to uneven stress.

[0066] In some specific embodiments, the tooling base 13 includes a supporting cylinder 22, a positioning seat 21 sleeved on the supporting cylinder 22 and slidably connected to the supporting cylinder 22, and a first spring 23. The positioning groove 24 is disposed on the positioning seat 21, and the first spring 23 is used to drive the positioning seat 21 to rise and reset.

[0067] It is understandable that the positioning seat 21 is slidably connected to the supporting cylinder 22 via the first spring 23, thereby enabling the tooling seat 13 to be adjusted to height adaptively.

[0068] Furthermore, the bottom wall of the positioning groove 24 is provided with a clearance hole 27 that passes through the positioning seat 21 from top to bottom. The clearance hole 27 is used to avoid the support cylinder 22. When the pump body 41 is embedded in the inner side of the annular gasket 40, the pump body 41 squeezes the positioning seat 21 to descend. The top of the support cylinder 22 can support the bottom surface of the annular gasket 40 so that the pump body 41 can be embedded in the annular gasket 40.

[0069] Understandably, when the pump body 41 is embedded in the annular gasket 40, the pump body 41 presses down on the positioning seat 21, and the top of the supporting cylinder 22 lifts up the bottom surface of the annular gasket 40, so as to avoid hard collision between the pump body 41 and the annular gasket 40 and protect easily deformable parts.

[0070] In some specific embodiments, the first spring 23 is sleeved on the outside of the supporting cylinder 22, and the outer wall of the supporting cylinder 22 is provided with an outer protruding ring 28. The outer protruding ring 28 abuts against the lower end of the first spring 23, and the top end of the first spring 23 abuts against the bottom wall of the positioning seat 21.

[0071] Understandably, the first spring 23 is sleeved on the outside of the supporting cylinder 22 and limited by the outer convex ring 28, which is compact in structure and provides stable restoring force.

[0072] In some specific embodiments, the outer wall of the supporting cylinder 22 is provided with a guide groove 29 extending vertically, and the positioning seat 21 is provided with a guide pin, which cooperates with the guide groove 29 for guidance.

[0073] Understandably, the guide groove 29 cooperates with the guide pin to ensure that the positioning seat 21 rises and falls vertically without deflection, and to maintain the positional accuracy of the annular gasket 40.

[0074] In some specific embodiments, the emulsion pump automatic feeding assembly machine also includes a gasket detection mechanism 3, which is located between the pump body feeding mechanism 2 and the glass bead feeding mechanism 4. The gasket detection mechanism 3 is used to detect whether the assembled product with the pump body 41 mounted on the tooling seat 13 has an annular gasket 40.

[0075] It is understandable that setting up an inspection station after the pump body 41 is loaded and before the glass beads 42 are assembled can intercept semi-finished products with missing gaskets in advance, avoid the waste of resources caused by subsequent ineffective assembly, and directly reduce costs.

[0076] Specifically, the gasket detection mechanism 3 can be set as a fiber optic sensor. Since the pump body 41 passes through the inside of the annular gasket 40, the relative position of the pump body 41 is different when there is a gasket and when there is no gasket. The position of the pump body 41 is detected by the fiber optic sensor to determine whether there is a gasket on the fixture 13.

[0077] In some specific embodiments, the automatic emulsion pump feeding and assembly machine also includes a qualified product discharge mechanism 11 and a defective product discharge mechanism 12. The qualified product discharge mechanism 11 and the defective product discharge mechanism 12 are located on the lower station side of the neck ring punching mechanism 10 along the rotation direction of the turntable 14. The qualified product discharge mechanism 11 is used to transfer the assembled and qualified emulsion pumps for discharge, and the defective product discharge mechanism 12 is used to move and discharge the semi-finished products and emulsion pump parts that fail the inspection during the assembly process.

[0078] It is understandable that qualified and defective products are separated during discharge to avoid mixing and scrapping the entire batch. In addition, defective parts can be recycled to reduce material loss and meet the requirements of lean production.

[0079] The workflow of the automatic emulsion pump wafer assembly machine in this embodiment is as follows: Under the rotation of the turntable 14, the tooling seat 13 moves orderly and precisely between each station. When the tooling seat 13 moves to the gasket feeding mechanism 1, the gasket feeding mechanism 1 takes out the annular gasket 40 and places it on the tooling seat 13. When the tooling seat 13 moves to the pump body feeding mechanism 2, the pump body feeding mechanism 2 clamps, takes out, and places the pump body 41 into the tooling seat 13. When the tooling seat 13 moves to the gasket detection mechanism 3, the gasket detection mechanism 3 detects the position of the pump body 41 and determines whether the annular gasket 40 exists. When the tooling seat 13 moves to the glass bead feeding mechanism 4, the glass bead feeding mechanism 4 separates the glass bead 42 and places the glass bead 42 into the pump body 41. When the tooling seat 13 moves to the spring feeding mechanism 5, the spring feeding mechanism 5 clamps the return spring 43 and places it into the pump body 41. When the tooling seat 13 moves to the piston assembly feeding mechanism 6, the piston assembly feeding mechanism 6 clamps the piston assembly 44 and places it into the pump body 41. When the tooling seat 13 moves to the piston assembly punching mechanism 7, the piston assembly punching mechanism 7 punches the piston assembly 44 so that the end of the piston assembly 44 is perpendicular to the tooling seat 13; when the tooling seat 13 moves to the threaded cover feeding mechanism 8, the threaded cover feeding mechanism 8 clamps the threaded cover 45 and places it on the tooling seat 13; when the tooling seat 13 moves to the neck ring feeding mechanism 9, the neck ring feeding mechanism 9 positions the piston assembly 44, clamps the neck ring 46 and passes it through the piston. At the end of group 44; when the tooling seat 13 moves to the neck ring punching mechanism 10, the neck ring punching mechanism 10 punches the neck ring 46 and the pump body 41 into one piece; when the tooling seat 13 moves to the qualified product discharge mechanism 11, the qualified product discharge mechanism 11 takes out the finished product and places it on the discharge channel for connection with subsequent processes; when the tooling seat 13 moves to the defective product discharge mechanism 12, the defective product discharge mechanism 12 takes out and removes the semi-finished product; at this time, the emulsion pump automatically feeds the sheet and completes the assembly.
