Description

Technical Field

[0001] The present invention relates to the technical field of foam pump assembly equipment, and particularly relates to a foam pump production line. Background Art

[0002] The foam pump commonly used in products such as hand sanitizer and facial cleanser includes a pump body, a housing, a pressing head, and a liquid suction pipe. The foam pump is installed on the hand sanitizer bottle through the housing. When a pressing operation is applied to the pressing head, the pump body works, sucks the liquid in the hand sanitizer bottle through the liquid suction pipe, and sprays it out. During the assembly process of the foam pump, after multiple parts are assembled into the pump body, the housing, the pressing head, and the liquid suction pipe are sequentially installed on the pump body.

[0003] With the continuous progress of automation technology, in order to improve work efficiency and save labor costs, foam pump manufacturing enterprises have developed some foam pump automatic assembly equipment, such as a component assembly equipment for foam pump parts disclosed in Chinese Patent with application number 201920830574.X, a foam pump main body installation and assembly machine disclosed in Chinese Patent with application number 201920826831.2, a full-automatic assembly machine for pressing foam pump disclosed in Chinese Patent with application number 201922213549.X, and an automatic assembly and cutting machine for the liquid suction pipe of a pressing foam pump disclosed in Chinese Patent with application number 201922313867.3.

[0004] The work of foam pump assembly includes the pump body assembly process, the process of assembling the housing and the pressing head on the pump body, and the process of assembling the liquid suction pipe on the pump body. Among them, the devices for completing the liquid suction pipe assembly generally have problems such as complex structure, cumbersome control, and unsatisfactory assembly efficiency. Summary of the Invention

[0005] The purpose of the present invention is to provide a foam pump production line to solve one or more technical problems existing in the prior art.

[0006] The technical solution adopted to solve the above technical problems:

[0007] The present invention discloses a foam pump production line, including a liquid suction pipe assembly device, and the liquid suction pipe assembly device includes:

[0008] A feeding seat, which is provided with a feeding channel for conveying the pump body. The feeding channel extends vertically. The upper end of the feeding channel is the feeding port, the lower end of the feeding channel is the discharging port, and the right side of the feeding channel is an open structure;

[0009] A positioning mechanism is provided at the front or rear side of the feeding channel, the positioning mechanism comprising a positioning member and an intercepting member, the positioning member is located below the intercepting member, and both the positioning member and the intercepting member can move forward and backward and be inserted into the feeding channel;

[0010] A clamping mechanism for clamping the pipette, the clamping mechanism being located on the right side of the feeding channel and arranged opposite to the positioning member, and the clamping mechanism being movable in the left and right directions;

[0011] The cutting mechanism is used for cutting the pipette, and the cutting mechanism is arranged on the clamping mechanism.

[0012] The present invention has at least the following beneficial effects: in the foam pump production line, the pipette assembly device is responsible for completing the pipette assembly process; in the pipette assembly device, the feeding seat is provided with a feeding channel extending up and down, so that the pump body can automatically move from the feed port to the discharge port due to the action of gravity, and there is no need to specially set up a feeding mechanism to transport the pump body out of the feeding channel, thereby simplifying the structure and control process of the pipette assembly device, and helping to improve the assembly efficiency; the positioning member and the intercepting member of the positioning mechanism are arranged spaced apart from each other up and down, and after the positioning member is inserted into the feeding channel, it can exert a positioning effect on the pump body abutting against the positioning member, so that the clamping mechanism can accurately insert the pipette onto the pump body, and then the cutting mechanism can cut the pipette The cutting is carried out to finally complete the assembly process of the pipette; then, the positioning part withdraws from the feeding channel, allowing the pump body with the pipette to fall downward due to gravity to complete the discharging work. At this time, the intercepting part intercepts other pump bodies to prevent them from escaping from the feeding channel; after the positioning part is inserted into the feeding channel, the intercepting part withdraws from the feeding channel so that the next pump body can abut against the positioning part, thereby orderly installing the pipette on the pump body. With this design, there is no need to set a position detector to detect the movement of the pump body to the assembly station, thereby making the structure of the pipette assembly device simpler, reducing the control steps, and facilitating the improvement of assembly efficiency; the foam pump production line has the advantages of simple structure, easy control and high assembly efficiency.

[0013] As a further improvement of the above technical solution, the positioning member includes a positioning cylinder and a positioning rod, the positioning cylinder is arranged on the feeding seat, the positioning rod extends forward and backward, the positioning rod is connected to the movable rod of the positioning cylinder, the feeding seat is provided with a positioning channel, the positioning channel is connected to the feeding channel, the positioning rod is located in the positioning channel, and can enter and exit the feeding channel.

[0014] In the structure of the positioning member, the positioning cylinder is installed on the feeding seat, and the positioning rod extends in the front-back direction. Under the driving action of the positioning cylinder, the positioning rod can move along the positioning channel and enter and exit the feeding channel. After the positioning rod extends into the feeding channel, the positioning rod can position the pump body abutted against it; after the positioning rod withdraws from the feeding channel, the pump body loses the supporting effect of the positioning rod and will automatically fall downward due to gravity, completing the blanking process.

[0015] As a further improvement of the above technical solution, the intercepting member includes an intercepting cylinder and an intercepting rod. The intercepting cylinder is provided on the feeding seat. The intercepting rod extends in the front-back direction. The intercepting rod is connected to the movable rod of the intercepting cylinder. The feeding seat is provided with an intercepting channel. The intercepting channel is located above the positioning channel. The intercepting channel communicates with the feeding channel. The intercepting rod is located in the intercepting channel and can enter and exit the feeding channel. In the structure of the intercepting member, the intercepting cylinder is fixed on the feeding seat. Under the driving action of the intercepting cylinder, the intercepting rod can move back and forth along the intercepting channel, so as to enter and exit the feeding channel, and can intercept the pump body in the feeding channel.

[0016] As a further improvement of the above technical solution, the cutting mechanism includes a fixed seat, a sliding seat, a cutting knife and a first linear driving component. The fixed seat is provided with a first through hole for the liquid suction pipe to pass through. The first through hole extends in the left-right direction. The fixed seat is provided with a sliding cavity, and the sliding cavity communicates with the first through hole. The cutting knife is provided on the sliding seat. The sliding seat is arranged in the sliding cavity. The output end of the first linear driving component is connected to the sliding seat to drive the cutting knife to move in a direction perpendicular to the first through hole and cut the liquid suction pipe.

[0017] In the cutting mechanism, the fixed seat is provided with a first through hole and a sliding cavity. The cutting knife is provided on the sliding seat, and the sliding seat is arranged in the sliding cavity. After the liquid suction pipe passes through the first through hole, the first linear driving component is started, and the first linear driving component drives the sliding seat to move linearly along the sliding cavity, so as to drive the cutting knife to move in a direction perpendicular to the first through hole to automatically cut the liquid suction pipe.

[0018] As a further improvement of the above technical solution, the fixed seat is arranged on the left side of the clamping mechanism. The fixed seat is elastically connected to the clamping mechanism so that the fixed seat can move left and right relative to the clamping mechanism. The lower end of the sliding cavity is an open structure. The sliding seat is located below the fixed seat. The cutting knife is provided on the upper surface of the sliding seat. The lower surface of the sliding seat is a first inclined surface, and the first inclined surface slopes upward from left to right. The first linear driving component is a support block. The support block is connected to the clamping mechanism. The support block is located below the sliding seat. The upper surface of the support block is a second inclined surface, and the first inclined surface and the second inclined surface are in abutting contact.

[0019] When the fixed seat, the sliding seat and the support block move leftward together with the clamping mechanism so that the liquid suction pipe is docked with the pump body at the feeding channel, the fixed seat will abut against the feeding seat. Since the fixed seat is elastically connected to the clamping mechanism and the sliding seat is arranged in the sliding cavity of the fixed seat, when the clamping mechanism and the support block continue to move leftward, the fixed seat and the sliding seat will move rightward relative to the clamping mechanism and the support block, causing the first inclined surface to move rightward relative to the second inclined surface, making the sliding seat rise relative to the fixed seat, and enabling the cutting knife to move upward to automatically cut the liquid suction pipe; after cutting is completed, the support block and the clamping mechanism will move rightward. At this time, because the fixed seat is elastically connected to the clamping mechanism, the fixed seat still abuts against the feeding seat, causing the fixed seat and the sliding seat to move leftward relative to the support block. The sliding seat moves downward due to its own gravity, keeping the first inclined surface and the second inclined surface in contact, and the cutting knife also moves downward with the sliding seat so that the liquid suction pipe can move into place along the first through hole, thereby enabling the liquid suction pipe to be docked with the next pump body; with such a clever structural design, there is no need to set up an electrically controlled first linear drive assembly, simplifying the control process of the foam pump production line and helping to improve the assembly efficiency.

[0020] As a further improvement of the above technical solution, the clamping mechanism includes a support seat, a movable clamping block, a second linear drive assembly and a third linear drive assembly; the output end of the second linear drive assembly is connected to the support seat to drive the support seat to move left and right. The support seat is provided with a second through hole for the liquid suction pipe to pass through. The second through hole extends in the left-right direction and is coaxially arranged with the first through hole. The support seat is provided with a movable cavity, and the movable cavity communicates with the second through hole. The movable clamping block is arranged in the movable cavity, and the output end of the third linear drive assembly is connected to the movable clamping block to drive the movable clamping block to move up and down. The upper surface of the movable clamping block and the support seat jointly define a clamping hole.

[0021] Under the driving action of the second linear drive assembly, the support seat can move in the left-right direction to insert the liquid suction pipe onto the pump body; the movable clamping block is arranged in the movable cavity of the support seat. Driven by the third linear drive assembly, the movable clamping block can move upward to exert a stable clamping force on a part of the liquid suction pipe located in the movable cavity, causing the liquid suction pipe to move together with the support seat and be installed on the pump body.

[0022] As a further improvement of the above technical solution, a first guiding rod is provided on the right side surface of the fixed seat. The first guiding rod extends horizontally. The supporting seat is provided with a first spring and a first guiding hole. The first guiding rod is connected to the first guiding hole. The first spring is sleeved on the first guiding rod. One end of the first spring is connected to the supporting seat, and the other end of the first spring is connected to the first guiding rod. The fixed seat is slidably connected to the supporting seat through the first guiding rod, which can improve the movement stability of the fixed seat. Moreover, the first spring is sleeved on the first guiding rod and is arranged between the supporting seat and the first guiding rod to realize the elastic connection between the fixed seat and the supporting seat.

[0023] As a further improvement of the above technical solution, the third linear driving assembly includes a wedge-shaped block, a second guiding rod and a second spring. The movable clamping block and the supporting seat jointly define a second guiding hole. The second guiding hole is communicated with and coaxially arranged with the first guiding hole. The wedge-shaped block is located below the first guiding rod and is connected to the first guiding rod. The wedge-shaped block can be inserted into the second guiding hole. There are multiple second guiding rods. The second guiding rods extend vertically. The second guiding rods are connected to the upper surface of the movable clamping block. The second guiding rods are slidably connected to the supporting seat. The second spring is sleeved on the second guiding rod. One end of the second spring is connected to the supporting seat, and the other end of the second spring is connected to the movable clamping block.

[0024] The movable clamping block is elastically connected to the supporting seat through the second guiding rod and the second spring. Under the elastic force of the second spring and the guiding action of the second guiding rod, the movable clamping block can automatically and smoothly move upward and jointly clamp the liquid suction pipe with the supporting seat. The wedge-shaped block is connected to the first guiding rod. When the fixed seat abuts against the feeding seat and the supporting seat continues to move towards the feeding seat, the right end of the first guiding rod will be inserted into the second guiding hole defined by the supporting seat and the movable clamping block. The wedge-shaped block is inserted into the second guiding hole along with the first guiding rod, causing the second guiding hole to be enlarged. Since the wedge-shaped block is located below the first guiding rod, the wedge-shaped block contacts the movable clamping block and applies a force to the movable clamping block, driving the movable clamping block to move downward, so that the clamping hole becomes larger and the clamping action of the supporting seat and the movable clamping block on the liquid suction pipe is released. With such a design, there is no need to set up an electrically controlled third linear driving assembly, which can effectively simplify the structure and control process of the liquid suction pipe assembling device and help improve the work efficiency.

[0025] As a further improvement of the above technical solution, the liquid suction pipe assembling device further includes a chassis. The chassis is provided with supporting guide rails. There are multiple supporting guide rails. The supporting guide rails extend horizontally. The supporting seat is slidably connected to the supporting guide rails. The supporting seat is arranged on the supporting guide rails of the chassis, which makes the supporting seat more stable during the linear movement.

[0026] As a further improvement of the above technical solution, the second linear drive assembly is located on the right side of the support base. The second linear drive assembly includes a drive motor, a turntable, and a connecting rod. One end of the connecting rod is hinged to the support base, and the other end of the connecting rod is hinged to a non-central position of the turntable. The rotation axis of the turntable extends vertically, and the output shaft of the motor is drivingly connected to the turntable.

[0027] A connecting rod is arranged between the turntable and the support base. Since the connecting rod is hinged to the turntable and the support base respectively, and the connecting rod is eccentrically connected to the turntable, when the motor drives the turntable to rotate around the axis extending vertically, the connecting rod moves with the rotation of the turntable and drives the support base to perform a linear reciprocating motion. With such a design, the clamping mechanism can be made to perform an uninterrupted left and right reciprocating motion, and the motor does not need to start and stop frequently and switch the rotation direction, which helps to extend the service life of the motor.

[0043] Referring to Figures 1 to 7 , several embodiments of the foam pump production line of the present invention are given below.

[0044] As Figures 1 to 7 shown, Embodiment 1 of the present invention provides a foam pump production line. The structure of the foam pump production line includes a pump body assembly device, a housing and a pressing head assembly device installed on the pump body, and a liquid suction pipe assembly device. Since the improvement of the present invention lies in the liquid suction pipe assembly device, and the pump body assembly device and the like belong to the prior art, those skilled in the art should understand the structure and working principle of the pump body assembly device and the like. Therefore, the structure and working principle of the liquid suction pipe assembly device will be specifically described below, and the description of the pump body assembly device and the like will not be repeated here.

[0045] As Figures 1 to 7 shown, the structure of the liquid suction pipe assembly device includes five major parts, namely a chassis 700, a feeding seat 100, a positioning mechanism, a clamping mechanism 600, and a cutting mechanism 500.

[0046] The chassis 700 can be made of metal such as iron, and provides a supporting role for the feeding seat 100, the positioning mechanism, the clamping mechanism 600, and the cutting mechanism 500.

[0047] The feeding seat 100 can be made of metal such as iron. The feeding seat 100 can be fixed on the chassis 700 by bolts. The feeding seat 100 is provided with a feeding channel 110, and the feeding channel 110 is used for conveying the pump body. The two ends of the feeding channel 110 extend in the up and down direction. The shape of the feeding channel 110 can be designed according to the shape of the pump body, as long as it satisfies that the pump body is clamped in the feeding channel 110 and can only move in the up and down direction. In some embodiments, the feeding channel 110 can apply a clamping effect on the housing installed on the pump body to prevent the pump body from moving in the left and right directions and the front and back directions.

[0048] Moreover, the upper end of the feeding channel 110 is the feeding port, so that the pump body can move to the feeding port under the conveying action of a conveying mechanism such as a vibrating disk, and automatically move downward along the feeding channel 110 due to gravity.

[0049] The lower end of the feeding channel 110 is the discharging port, so that the pump body can fall from the discharging port after completing the liquid suction pipe installation process, leave the feeding channel 110, and automatically complete the blanking work.

[0050] The right side of the feeding channel 110 is an open structure. The design of the open structure allows the liquid suction pipe installation end of the pump body to be exposed outside the feeding channel 110, so that the liquid suction pipe can move to the left and be inserted into the liquid suction pipe installation end of the pump body, while the pressing head of the pump body is located inside the feeding channel 110.

[0051] In addition, the chassis 700 is provided with a product outlet, which is located below the discharge port of the feeding channel 110. The chassis 700 is provided with a discharge plate 300, which can be made of metal. The discharge plate 300 is arranged at the product outlet and can be fixed to the chassis 700 by welding or bolt connection. The discharge plate 300 has a downwardly inclined discharge surface. After the pump body and the liquid suction pipe are connected, the pump body drops downward from the discharge port of the feeding channel 110, passes through the product outlet and the discharge plate 300 in sequence, and then falls into the product box to complete product collection.

[0052] As Figure 1 shown, the positioning mechanism is arranged on the front side of the feeding channel 110. In some embodiments, the positioning mechanism is arranged on the rear side of the feeding channel 110.

[0053] The positioning mechanism includes a positioning member and an intercepting member. The positioning member is located below the intercepting member, and the positioning member can move back and forth and insert into the feeding channel 110.

[0054] Specifically, the positioning member includes a positioning cylinder 220 and a positioning rod 221. The positioning cylinder 220 can be a single-axis cylinder or a double-axis cylinder. The positioning cylinder 220 is arranged on the feeding base 100 by bolts, and the moving rod of the positioning cylinder 220 can extend and retract in the front-rear direction.

[0055] Both ends of the positioning rod 221 extend in the front-rear direction. The positioning rod 221 can be a round rod or a square rod. The positioning rod 221 is connected and fixed to the moving rod of the positioning cylinder 220. In some embodiments, a positioning plate can be used to replace the positioning rod 221.

[0056] The feeding base 100 is provided with a positioning channel, and both ends of the positioning channel extend in the front-rear direction. The cross-sectional shape of the positioning channel can be a round hole, a square, etc., as long as it can provide a receiving space for the positioning rod 221.

[0057] Moreover, the positioning channel communicates with the feeding channel 110, and the positioning rod 221 is located inside the positioning channel. When the moving rod of the positioning cylinder 220 extends or contracts, the positioning rod 221 will move in the front-rear direction and can enter and exit the feeding channel 110.

[0058] When the positioning rod 221 enters the feeding channel 110 due to the elongation of the movable rod of the positioning cylinder 220, the positioning rod 221 will support and position the pump body abutting against it, preventing the pump body from falling downward. When the positioning rod 221 withdraws from the feeding channel 110 due to the retraction of the movable rod of the positioning cylinder 220, the pump body will lose the support of the positioning rod 221 and automatically fall downward due to the influence of gravity, and come out from the discharge port of the feeding channel 110 to complete the feeding process.

[0059] Moreover, the intercepting member can move back and forth and insert into the feeding channel 110.

[0060] Specifically, the intercepting member includes an intercepting cylinder 210 and an intercepting rod 211.

[0061] The intercepting cylinder 210 can be a single-axis cylinder or a double-axis cylinder. The intercepting cylinder 210 is fixedly arranged on the feeding seat 100, such as by bolt connection. The movable rod of the intercepting cylinder 210 can move in the front-back direction.

[0062] The intercepting rod 211 can be a round rod or a square rod. The two ends of the intercepting rod 211 extend in the front-back direction, and the intercepting rod 211 is fixedly connected to the movable rod of the intercepting cylinder 210.

[0063] The feeding seat 100 is provided with an intercepting channel. The two ends of the intercepting channel extend in the front-back direction. The cross-sectional shape of the intercepting channel can be square, circular, etc., as long as it can accommodate the intercepting rod 211. Moreover, the intercepting channel is located above the positioning channel, the intercepting channel communicates with the feeding channel 110, and the intercepting rod 211 is arranged in the intercepting channel. When the movable rod of the intercepting cylinder 210 elongates or contracts, the intercepting rod 211 can move in the front-back direction and enter and exit the feeding channel 110.

[0064] When the intercepting rod 211 enters the feeding channel 110 due to the elongation of the movable rod of the intercepting cylinder 210, the intercepting rod 211 can intercept the pump body in the feeding channel 110. Since the intercepting rod 211 is located above the positioning rod 221 and the distance between the intercepting rod 211 and the positioning rod 221 reserves one pump body, the function of the intercepting rod 211 is to intercept all the pump bodies above the intercepting rod 211, prevent them from continuing to move downward, and prevent them from affecting the liquid suction pipe assembly work of the pump body located on the positioning rod 221. When the intercepting rod 211 withdraws from the feeding channel 110 due to the retraction of the movable rod of the intercepting cylinder 210, the pump bodies above the intercepting rod 211 move downward due to the loss of the restricting effect of the intercepting rod 211, so that the positioning rod 221 can position the next pump body.

[0065] It can be understood that each feeding channel 110 is configured with an intercepting member and a positioning member. In this embodiment, a feeding base 100 is provided with two feeding channels 110. The feeding channel 110 located at the front side is the first feeding channel 110. Correspondingly, the intercepting member and the positioning member are located at the front side of the first feeding channel 110. The feeding channel 110 located at the rear side is the second feeding channel 110. Correspondingly, the intercepting member and the positioning member are located at the rear side of the second feeding channel 110.

[0066] As Figures 1 to 7 shown, the clamping mechanism 600 is used to clamp the liquid suction tube and can drive the liquid suction tube to move towards the liquid suction tube installation end of the pump body.

[0067] Since the right side of the feeding channel 110 is an open structure, therefore, the clamping mechanism 600 is located on the right side of the feeding channel 110 and is arranged opposite to the positioning member, so that the liquid suction tube can be accurately inserted into the pump body. The clamping mechanism 600 can move linearly in the left-right direction.

[0068] Specifically, the structure of the clamping mechanism 600 includes a second linear drive assembly, a third linear drive assembly, a support base 630, and a movable clamping block 650.

[0069] The support base 630 can be made of metal. The support base 630 is arranged above the chassis 700. The chassis 700 is provided with support guide rails 710. There are multiple support guide rails 710. The two ends of the support guide rails 710 extend in the left-right direction. The support base 630 is slidably connected to the support guide rails 710. In this embodiment, the support guide rails 710 are round rods. The two ends of the support guide rails 710 are fixedly connected to the chassis 700. There are two support guide rails 710, which are respectively arranged on the front side and the rear side of the support base 630. The support base 630 is provided with support guide holes 620. The support guide holes 620 penetrate through the left side surface and the right side surface of the support base 630. The support guide holes 620 are round holes that match the support guide rails 710. Since the support guide rails 710 are adaptively connected to the support guide holes 620, the support base 630 is supported, and moreover, it can move smoothly along the length direction of the support guide rails 710.

[0070] The second linear drive assembly can be a cylinder, an oil cylinder, an electric cylinder, etc. The second linear drive assembly can be arranged on the right side or the left side of the support base 630. The output end of the second linear drive assembly can move in the left-right direction. If the second linear drive assembly is a cylinder, the movable rod of the cylinder is the output end. The output end of the second linear drive assembly is connected to the support base 630 to drive the support base 630 to move left and right.

[0071] In some embodiments, the second linear drive assembly is located on the right side of the support base 630. The second linear drive assembly includes a drive motor 410, a turntable 430, and a connecting rod 420. The motor 410 can be fixed to the chassis 700 by bolts and can be provided below the chassis 700. The turntable 430 can be a disc made of metal. The rotation axis of the turntable 430 extends in the vertical direction. Specifically, a rotating shaft is provided on the lower surface of the turntable 430 and is installed on the chassis 700 through a bearing. The turntable 430 can rotate relative to the chassis 700 about the central axis extending in the vertical direction. The output shaft of the motor 410 is in transmission connection with the turntable 430. Specifically, the output shaft of the motor 410 can be connected to the rotating shaft of the turntable 430 through a coupling, a gear transmission structure, a chain transmission structure, etc. When the motor 410 is enabled, the output shaft of the motor 410 can drive the turntable 430 to rotate about its own central axis.

[0072] One end of the connecting rod 420 is hinged to the support base 630 through a vertically extending hinge shaft, and the other end of the connecting rod 420 is hinged to a non-central position of the turntable 430 through a vertically extending hinge shaft. For example, the hinged position of the connecting rod 420 and the turntable 430 is located at the edge of the turntable 430.

[0073] Since the connecting rod 420 and the turntable 430 are designed with an eccentric connection, when the motor 410 is working, the connecting rod 420 can drive the support base 630 to perform a linear reciprocating motion in the left-right direction due to the driving action of the turntable 430. With such a design, the clamping mechanism 600 can perform an uninterrupted left-right reciprocating motion. Moreover, the motor 410 does not need to be frequently started, stopped, and switched in the rotation direction, which helps to extend the service life of the motor 410.

[0074] The support base 630 is provided with a second through hole 610 for the liquid suction pipe to pass through. The second through hole 610 can be a round hole that fits the liquid suction pipe. The central axis of the second through hole 610 extends in the left-right direction. The support base 630 is provided with a movable cavity 634. The opening of the movable cavity 634 can be downward, and the movable cavity 634 is communicated with the second through hole 610.

[0075] The movable clamping block 650 is arranged in the movable cavity 634. The movable clamping block 650 is in contact with the wall surface of the movable cavity 634, so that the movable clamping block 650 can only move stably in the vertical direction.

[0076] The upper surface of the movable clamping block 650 and the support seat 630 jointly define a clamping hole. The two ends of the clamping hole extend left and right, and the clamping hole communicates with the second through hole 610. Specifically, the upper surface of the movable clamping block 650 is provided with a first groove 651. The first groove 651 penetrates through the left side surface and the right side surface of the movable clamping block 650, and the opening of the first groove 651 faces upward. The support seat 630 is provided with a third groove 633. The two ends of the third groove 633 extend in the left-right direction and communicate with the second through hole 610, and the opening of the third groove 633 faces downward. After the movable clamping block 650 moves upward in place, the first groove 651 and the third groove 633 jointly form a clamping hole to exert a strong and stable clamping effect on the liquid suction pipe.

[0077] The shape of the movable clamping block 650 is not specifically limited, as long as it can move up and down and jointly define a clamping hole with the support seat 630.

[0078] The third linear driving component can be an electric cylinder, a cylinder, etc. If a cylinder is adopted, the movable rod of the cylinder is the output end of the third linear driving component. The output end of the third linear driving component is connected to the movable clamping block 650 to drive the movable clamping block 650 to move linearly in the up-down direction. The third linear driving component can be arranged on the upper surface of the support seat 630, and the support seat 630 is provided with a through hole for the output end of the third linear driving component to pass through. It can be understood that one, two or more third linear driving components can be provided, which is not limited here.

[0079] As Figures 1 to 7 shown, the cutting mechanism 500 is used to cut the liquid suction pipe. The cutting mechanism 500 can be fixedly arranged on the clamping mechanism 600 by bolts and can move left and right together with the clamping mechanism 600. The cutting mechanism 500 can be arranged on the left side of the clamping mechanism 600, or a cavity can be provided at the left end of the clamping mechanism 600, and the cavity communicates with the second through hole 610 to allow the liquid suction pipe to pass through. The cutting mechanism 500 is arranged in the cavity and can cut the liquid suction pipe passing through the cavity.

[0080] In some embodiments, the structure of the cutting mechanism 500 includes a cutting knife 570, a fixed seat 520, a first linear driving component and a sliding seat 530.

[0081] The fixed seat 520 is provided with a first through hole 510. The two ends of the first through hole 510 extend in the left-right direction. The first through hole 510 is coaxially arranged with the second through hole 610, and moreover, the first through hole 510 communicates with the second through hole 610 to allow the liquid suction pipe to pass through the second through hole 610 and the first through hole 510 in sequence. The first through hole 510 is a round hole that fits the liquid suction pipe.

[0082] The inside of the fixed seat 520 is hollow to form a sliding cavity 521, and the sliding cavity 521 communicates with the first through hole 510.

[0083] The cutting blade 570 can be mounted on the sliding base 530 by welding or bolting, and the cutting blade 570 can move along with the sliding base 530 .

[0084] In this embodiment, the cutting blade 570 is V-shaped when viewed from above. In other embodiments, the cutting blade 570 can be a straight-shaped blade.

[0085] The sliding seat 530 is disposed within the sliding cavity 521. The sliding seat 530 contacts the wall of the sliding cavity 521, forcing the sliding seat 530 to move smoothly only in a direction perpendicular to the first through-hole 510. For example, the sliding seat 530 can move forward and backward to allow the cutter 570 to cut the pipette. Alternatively, the sliding seat 530 can move upward and downward to allow the cutter 570 to complete the pipette cutting process.

[0086] It will be appreciated that, to improve cutting efficiency and quality, the fixed base 520 may be provided with a tool cavity that mates with the cutting blade 570, and the tool cavity communicates with the first through-hole 510. If the cutting blade 570 has a V-shaped cross-section, the tool cavity will be a cavity with a V-shaped cross-section. When the cutting blade 570 moves with the sliding base 530, the cutting blade 570 can move along the tool cavity and effectively cut the portion of the pipette located within the tool cavity. The shapes of the fixed base 520 and the sliding base 530 are not limited.

[0087] The first linear drive assembly can be an electric cylinder, a pneumatic cylinder, or an oil cylinder. If a pneumatic cylinder is used, the movable rod of the cylinder serves as the output end of the first linear drive assembly. The output end of the first linear drive assembly is connected to the sliding seat 530 to drive the cutting knife 570 to move in a direction perpendicular to the first through hole 510 and cut the pipette. In some embodiments, the sliding seat 530 can drive the cutting knife 570 to move up and down. In this case, the first linear drive assembly can be disposed on the fixed seat 520. The output end of the first linear drive assembly can move up and down and be connected and fixed to the sliding seat 530 to achieve the lifting and lowering of the sliding seat 530 relative to the fixed seat 520, thereby allowing the cutting knife 570 to move upward and cut the pipette.

[0088] In some embodiments, as Figure 2 、 Figure 3 、 Figure 5 and Figure 6 As shown, the fixing seat 520 is disposed on the left side of the clamping mechanism 600 , and the fixing seat 520 is elastically connected to the clamping mechanism 600 so that the fixing seat 520 can move left and right relative to the clamping mechanism 600 .

[0089] Specifically, a first guide rod 540 is provided on the right side surface of the fixed seat 520. The first guide rod 540 can be fixed to the fixed seat 520 by welding or bolt connection. The first guide rod 540 can be a round rod or a square rod, and both ends of the first guide rod 540 extend in the left-right direction. The support seat 630 is provided with a first guide hole. Both ends of the first guide hole extend in the left-right direction. The shape of the first guide hole matches the shape of the first guide rod 540. The first guide rod 540 passes through the first guide hole and is connected to the wall surface of the first guide hole, prompting the first guide rod 540 to move left and right along the first guide hole, which helps to improve the movement stability of the fixed seat 520. It can be understood that the number of the first guide rods 540 can be one, two or more, which is not limited herein.

[0090] Moreover, the support seat 630 is provided with a first spring 670. Both ends of the first spring 670 extend in the left-right direction. The first spring 670 is sleeved on the first guide rod 540. One end of the first spring 670 is fixedly connected to the support seat 630, and the other end of the first spring 670 is fixedly connected to the first guide rod 540, such as by welding or clamping. In other embodiments, a limit block is provided at the right end of the first guide rod 540. The limit block can be located on the right side of the first guide hole to prevent the first guide rod 540 from disengaging from the first guide hole. At this time, the first spring 670 is sleeved on the first guide rod 540, and its connection with the support seat 630 and the fixed seat 520 is realized by abutting.

[0091] In this embodiment, as Figure 6 shown, a sleeve 660 is provided on the right side surface of the support seat 630. The sleeve 660 has a receiving cavity 661 with an opening facing left. The receiving cavity 661 communicates with the first guide hole. A through hole for the first guide rod 540 to pass through is provided on the right side surface of the sleeve 660. The through hole communicates with the receiving cavity 661. The sleeve 660 can be fixed to the support seat 630 by bolts. A stop block 560 is provided on the first guide rod 540. The stop block 560 can be connected and fixed to the first guide rod 540 by welding, bolt connection or integral molding process. The stop block 560 can be in a circular ring shape. The first spring 670 is arranged in the sleeve 660. The first spring 670 is sleeved on the first guide rod 540. The right end of the first spring 670 abuts against the inner right wall surface of the receiving cavity 661, and the left end of the first spring 670 abuts against the stop block 560. Moreover, the setting of the stop block 560 can prevent the first guide rod 540 from withdrawing leftward from the first guide hole.

[0092] And, the lower end of the sliding cavity 521 is an open structure so that the lower end of the sliding seat 530 protrudes from the open structure of the sliding cavity 521.

[0093] The fixing base 520 is located above the sliding base 530, and the cutting knife 570 is arranged on the upper surface of the sliding base 530. The lower surface of the sliding base 530 is a first inclined surface, which is inclined upward from left to right.

[0094] The first linear driving component is the support block 640. The dimension of the support block 640 in the front-back direction can be the same as that of the sliding base 530. The support block 640 is fixedly connected to the clamping mechanism 600, such as by bolt connection or welding. The support block 640 is located below the sliding base 530. The upper surface of the support block 640 is a second inclined surface, which is inclined upward from left to right.

[0095] The first inclined surface and the second inclined surface are in contact and abut against each other. The support block 640 provides a supporting effect on the sliding base 530, which can prevent the sliding base 530 from completely disengaging from the sliding cavity 521.

[0096] It can be understood that the first inclined surface and the second inclined surface are in contact with each other, and their inclination angles can be set according to actual situations, such as 10°, 20°, etc., which are not limited herein.

[0097] When the clamping mechanism 600 moves to the left, the fixing base 520, the sliding base 530 and the support block 640 also move to the left together, so that the liquid suction pipe is docked with the pump body at the feeding channel 110. After the fixing base 520 moves to the left in place, the fixing base 520 will abut against the feeding base 100. Since the fixing base 520 and the clamping mechanism 600 are elastically connected, and the sliding base 530 is arranged in the sliding cavity 521 of the fixing base 520, when the clamping mechanism 600 and the support block 640 continue to move to the left, the fixing base 520 and the sliding base 530 will move to the right relative to the clamping mechanism 600 and the support block 640, so that the first inclined surface moves to the right relative to the second inclined surface, and then the sliding base 530 rises relative to the fixing base 520, causing the cutting knife 570 to move upward and automatically cut the liquid suction pipe.

[0098] After the cutting work of the liquid suction pipe is completed, the support block 640 and the clamping mechanism 600 will move to the right under the driving action of the second linear driving component. At this time, since the fixing base 520 and the clamping mechanism 600 are elastically connected, the fixing base 520 is still abutted against the right side surface of the feeding base 100 under the elastic force of the first spring 670, causing the fixing base 520 and the sliding base 530 to move to the left relative to the support block 640. At this time, the sliding base 530 moves downward due to its own gravity, so that the first inclined surface and the second inclined surface always remain in contact, and the cutting knife 570 also moves downward with the sliding base 530 to create enough space for the liquid suction pipe to move to the left along the first through hole 510 in place, so that the liquid suction pipe is docked with the next pump body.

[0099] With such a clever structural design, there is no need to set up an electrically controlled first linear drive assembly, which simplifies the control process of the foam pump production line and helps improve the assembly efficiency.

[0100] Further, as Figure 3 , Figure 4 , Figure 6 and Figure 7 shown, the third linear drive assembly includes a wedge-shaped block 550, a second guide rod 682 and a second spring 681.

[0101] The movable clamping block 650 and the support seat 630 jointly define a second guide hole. The second guide hole is communicated with and coaxially arranged with the first guide hole so that the first guide rod 540 can pass through the first guide hole and the second guide hole and extend into the sleeve 660.

[0102] Specifically, the upper surface of the movable clamping block 650 is provided with a second groove 652 with an upward opening. The second groove 652 penetrates the left side surface and the right side surface of the movable clamping block 650. The support seat 630 is provided with a fourth groove 632 with a downward opening. The two ends of the fourth groove 632 extend along the left-right direction and are communicated with the first guide hole. After the movable clamping block 650 moves upward in place, the second groove 652 and the fourth groove 632 jointly define the second guide hole. The second guide hole can be a round hole or a square hole. In this embodiment, the second guide hole is a round hole.

[0103] There are multiple second guide rods 682. The two ends of the second guide rod 682 extend along the up-down direction. The lower end of the second guide rod 682 is fixedly connected to the upper surface of the movable clamping block 650. The second guide rod 682 is slidably connected to the support seat 630, which makes the movable clamping block 650 move more smoothly up and down.

[0104] Moreover, the second spring 681 is sleeved on the second guide rod 682. One end of the second spring 681 is fixedly connected to the support seat 630, and the other end of the second spring 681 is fixedly connected to the upper surface of the movable clamping block 650. Under the elastic force of the second spring 681, the movable clamping block 650 will automatically move upward and clamp the liquid suction pipe with the support seat 630.

[0105] In this embodiment, the support seat 630 is provided with a connection hole 631. The connection hole 631 allows the lower end of the second guide rod 682 to pass through. The connection hole 631 can be a round hole, and the axis of the connection hole 631 extends along the up-down direction. The second guide rod 682 can be a connecting bolt. There can be two second guide rods 682.

[0106] After passing through the connection hole 631, the second guide rod 682 is connected to the threaded hole of the movable clamping block 650, so that the second guide rod 682 is fixedly connected to the movable clamping block 650. The second spring 681 is sleeved on the second guide rod 682, and the lower end of the second spring 681 abuts against the upper surface of the support seat 630, and the upper end of the second spring 681 abuts against the upper end of the second guide rod 682.

[0107] The wedge-shaped block 550 is located below the first guide rod 540 and is fixedly connected to the first guide rod 540. The wedge-shaped block 550 can be connected to the first guide rod 540 by welding or integral molding process. The wedge-shaped block 550 can move left and right with the first guide rod 540 and can enter and exit the second guide hole.

[0108] If the first guide rod 540 is a square rod and the first guide hole and the second guide hole are square holes, the wedge-shaped block 550 can be a triangular prism, the length of which extends in the front and rear directions. The lower surface of the wedge-shaped block 550 is an inclined surface, and the inclined surface is inclined upward from left to right. When the wedge-shaped block 550 is inserted into the second guide hole, the wedge-shaped block 550 contacts the movable clamping block 650 and drives the movable clamping block 650 to move downward to expand the second guide hole so as to accommodate the wedge-shaped block 550. Since the movable clamping block 650 moves downward, the clamping hole will also become larger, resulting in the cancellation of the pressing action of the movable clamping block 650 on the liquid suction pipe, thereby releasing the clamping action of the clamping mechanism 600 on the liquid suction pipe.

[0109] If the first guide rod 540 is a round rod and the first guide hole and the second guide hole are round holes, the wedge-shaped block 550 can be a semi-circular truncated cone and is coaxially arranged with the first guide rod 540. When the wedge-shaped block 550 is inserted into the second guide hole, the outer peripheral surface of the wedge-shaped block 550 contacts the movable clamping block 650 and can drive the movable clamping block 650 to move downward against the elastic force of the second spring 681.

[0110] When the fixed seat 520 abuts against the feeding seat 100 and the support seat 630 continues to move in the direction of the feeding seat 100 (i.e., the left direction), the right end of the first guide rod 540 will be inserted into the second guide hole defined by the support seat 630 and the movable clamping block 650. The wedge-shaped block 550 is inserted into the second guide hole along with the first guide rod 540, causing the second guide hole to be expanded. Since the wedge-shaped block 550 is located below the first guide rod 540, the wedge-shaped block 550 contacts the movable clamping block 650 and applies a force to the movable clamping block 650, driving the movable clamping block 650 to move downward, so that the clamping hole becomes larger, and the clamping action of the support seat 630 and the movable clamping block 650 on the liquid suction pipe is released.

[0111] The first guide rod 540 can not only enable the fixed seat 520 to move smoothly left and right relative to the support seat 630, but also cooperate with the wedge-shaped block 550 to promote the automatic downward movement of the movable clamping block 650.

[0112] With this design, there is no need to set up a third electrically controlled linear drive component, which can effectively simplify the structure and control process of the pipette assembly device, helping to improve work efficiency; moreover, it can reduce the weight of the clamping mechanism 600 and the cutting mechanism 500, thereby reducing the energy consumption of the second linear drive component.

[0113] In the foam pump production line provided in the embodiment of the present invention, the pipette assembly device is responsible for completing the pipette assembly process; in the pipette assembly device, the feeding seat 100 is provided with a feeding channel 110 extending up and down, so that the pump body can automatically move from the feed port to the discharge port due to the action of gravity, and there is no need to specially set up a feeding mechanism to transport the pump body out of the feeding channel 110, thereby simplifying the structure and control process of the pipette assembly device and helping to improve assembly efficiency.

[0114] In addition, the positioning member and the intercepting member of the positioning mechanism are arranged in an upper and lower spaced relationship. After the positioning member is inserted into the feeding channel 110, it can exert a positioning effect on the pump body that abuts against the positioning member, so that the clamping mechanism 600 can accurately insert the pipette into the pump body, and then the cutting mechanism 500 cuts the pipette, and finally completes the pipette assembly process; then, the positioning member withdraws from the feeding channel 110, allowing the pump body with the pipette to fall down due to gravity to complete the discharging work. At this time, the intercepting member exerts an intercepting effect on other pump bodies to prevent them from escaping from the feeding channel 110; after the positioning member is inserted into the feeding channel 110, the intercepting member withdraws from the feeding channel 110, so that the next pump body abuts against the positioning member, thereby orderly installing the pipette on the pump body. With this design, there is no need to set a position detector to detect the movement of the pump body to the assembly station, thereby making the structure of the pipette assembly device simpler, reducing the control steps, and being conducive to improving assembly efficiency.

[0115] The foam pump production line has the advantages of simple structure, easy control and high assembly efficiency.

[0116] It is understandable that the pipette can be unwound by a reel mechanism, and the pipette can be moved to the left along the second through hole 610 and the first through hole 510 .

[0117] The above specifically describes the preferred embodiments of the present invention, but the invention is not limited to the embodiments. Those skilled in the art may make various equivalent modifications or substitutions without violating the spirit of the present invention. These equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
