For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0050] A piston product assembly device comprises a frame 1, a first feeding mechanism 2, a second feeding mechanism 3, a lower hopper 4 and a material transfer mechanism 5;

[0051] The frame 1 includes an upper mounting frame 11 and a lower mounting frame 12 which are arranged one above the other. The first feeding mechanism 3, the second feeding mechanism 3 and the lower hopper 4 are all mounted on the upper mounting frame 11, and the material moving mechanism 5 is movably mounted on the lower mounting frame 12.

[0052] The upper mounting frame 11 includes a material picking station, an installation station and a material unloading station. The material picking station is located above the first feeding mechanism 3, the installation station is located above the second feeding mechanism 3, and the material unloading station is located above the unloading hopper 4. The material moving mechanism 5 realizes the movement among the three stations of the material picking station, the installation station and the material unloading station.

[0053] In the prior art, the assembly of the piston and the clamping strip in the Puffing Tube of medical supplies is generally carried out by manual installation of the assembly parts to be assembled. When this installation method is used, the accuracy of the assembly dimensions cannot be fully guaranteed during the assembly process, resulting in a large NG rate in the overall assembly of the subsequent products. At the same time, the manual operation efficiency is low, which easily leads to high labor costs.

[0054] This technical solution proposes a piston product assembly device, which can realize the material picking, assembly and unloading processes at the same time, has a simple and reasonable structure, and is conducive to reducing production costs. Specifically, it includes a frame 1, a first feeding mechanism 3, a second feeding mechanism 3, a unloading hopper 4 and a material shifting mechanism 5. The first feeding mechanism 2 is used to convey the card strip 6, the second feeding mechanism 3 is used to convey the piston 7, and the unloading hopper 4 is used to receive the assembled card strip 6 and piston 7. The upper mounting frame 11 includes a material picking station, an installation station and an unloading station. The material shifting mechanism 5 can realize the movement among the three stations of the material picking station, the installation station and the unloading station.

[0055] Furthermore, the working steps of a piston product assembly device in the technical solution are as follows:

[0056] (1) The material transfer device moves to the material taking station and takes out the card strip 6 from the first feeding mechanism 3;

[0057] (2) After the material moving device moves the clamping strip 6 to the installation position, the clamping strip 6 and the piston 7 are pressed to complete the installation;

[0058] (3) The material moving device moves the assembled clamping strip 6 and piston 7 to the unloading station for unloading.

[0059] To further illustrate, the material moving mechanism 5 includes a material taking head 51, a horizontal moving device 52 and a vertical moving device 53;

[0060] The vertical moving device 53 is installed on the top of the horizontal moving device 52, and the horizontal moving device 52 drives the vertical moving device 53 to move horizontally;

[0061] The output shaft of the vertical moving device 53 passes through the horizontal moving device 52 and is connected to the material taking head 51 , and the vertical moving device 53 drives the material taking head 51 to move up and down.

[0062] In order to enable the material moving mechanism 5 to simultaneously realize the processes of material picking, assembly and unloading, the material moving mechanism 5 in the present technical solution includes a material picking head 51, a horizontal moving device 52 and a vertical moving device 53. The material picking head 51 is used to take out the card strip 6. The horizontal moving device 52 can drive the material picking head 51 to move left and right through the vertical moving device 53. The vertical moving device 53 can drive the material picking head 51 to move up and down. The setting of the horizontal moving device 52 and the vertical moving device 53 makes the movement of the material picking head 51 more flexible, which is conducive to satisfying the material moving mechanism 5 to simultaneously realize the processes of material picking, assembly and unloading, and the structure is simple and reasonable.

[0063] It should be noted that the structure and size of the material taking head 51 can be designed according to actual needs (ie, the piston 7 that actually needs to be assembled).

[0064] To further illustrate, the horizontal moving device 52 includes a horizontal driving member 521, a horizontal moving plate 522, a guide member 523 and a horizontal guide rail 524;

[0065] The horizontal driving member 521 is used to drive the horizontal movement of the horizontal moving plate 522; the guide member 523 is installed at the bottom of the horizontal moving plate 523, and a guide groove matching the horizontal guide rail 524 is opened at the bottom of the guide member 523, and the horizontal guide rail 524 slides in the guide groove.

[0066] The horizontal moving device 2 in the present technical solution includes a horizontal driving member 521, a horizontal moving plate 522, a guide member 523 and a horizontal guide rail 524. The guide member 523 is installed at the bottom of the horizontal moving plate 523. A guide groove matching the horizontal guide rail 524 is provided at the bottom of the guide member 523. The horizontal guide rail 524 slides in the guide groove, which is beneficial to ensure the stability of the material moving mechanism 5 during the horizontal movement process and prevent the clamping strip 6 or the assembled clamping strip 6 and the piston 7 from detaching from the material taking head 51 during the movement of the material moving mechanism 5.

[0067] Further explained, the vertical moving device 53 includes a vertical driving member 531 and a guide assembly 532. The output shaft of the vertical driving member 531 passes through the horizontal moving plate 522 and is connected to the material picking head 51. The vertical driving member 531 is used to drive the material picking head 51 to move up and down; the guide assembly 532 passes through the horizontal moving plate 522 and is movably connected to the end of the material picking head 51. The vertical moving device 53 drives the guide assembly 532 to move up and down through the material picking head 51.

[0068] The vertical moving device 53 in the present technical solution includes a vertical driving member 531 and a guide assembly 532. The output shaft of the vertical driving member 531 passes through the horizontal moving plate 522 and is connected to the material picking head 51. It is only necessary to connect the material picking head 51 with the output shaft of the vertical driving member 531 to realize the up and down and horizontal movement of the material picking head 51 in the product assembly equipment. The structure is compact, which is beneficial to saving the floor space of the product assembly equipment.

[0069] The guide assembly 532 is movably connected to the end of the material picking head 51 through the horizontal movable plate 522, and the vertical movable device 53 drives the guide assembly 532 to move up and down through the material picking head 51, which is beneficial to ensure the stability of the material moving mechanism 5 during the up and down movement, and prevent the clamping strip 6 or the assembled clamping strip 6 and the piston 7 from detaching from the material picking head 51 during the movement of the material moving mechanism 5.

[0070] Further explained, the guide assembly 532 includes a guide rod 5321 and a guide connecting plate 5322, the guide rods 5321 are at least two, and the guide rods 5321 are respectively located on both sides of the vertical driving member 531; the guide connecting plate 5322 is located at the top of the guide rod 5321, and the guide connecting plate 5322 is used to connect all the guide rods 5321.

[0071] The guide assembly 532 includes a guide rod 5321 and a guide connecting plate 5322. The guide connecting plate 5322 is used to connect all the guide rods 5321 to guide the up and down movement of the material picking head 51. At the same time, the guide rods 5321 are respectively located on both sides of the vertical driving member 531, which is beneficial to ensure the flatness of the material picked up by the material picking head 51 and ensure the effectiveness of material picking.

[0072] Preferably, the side edge of the guide connecting plate 5322 along the length direction is recessed inwardly to form an avoidance position 53221 , and the avoidance position 53221 is used to avoid the vertical driving member 531 .

[0073] Preferably, the guide assembly 532 further includes a limit block 5323 , which is detachably mounted on a side wall of the guide rod 5321 to limit the up and down movement of the guide rod 5321 .

[0074] The guide assembly 532 also includes a limit block 5323, which is helpful to limit the movable distance of the guide assembly 532. The limit block 5323 is detachably mounted on the side wall of the guide rod 5321, which is helpful to limit the descending distance of the guide assembly 532 according to different assembly parts, thereby ensuring the effectiveness of material collection.

[0075] Further, the material transfer mechanism 5 further includes a material discharge device 54, and the material discharge device 54 includes a trigger member 541, a response member 542, a material discharge clamping member 543 and a reset member 544;

[0076] The trigger member 541 is installed on the side of the horizontal moving plate 522 facing the unloading station, the response member 542 is installed on the upper mounting frame 11, and the response member 542 is close to the unloading station, and the unloading clamp 543 is installed at the bottom of the response member 542; the reset member 544 is installed between the response member 542 and the upper mounting frame 11, one end of the reset member 544 is against the lower surface of the response member 542, and the other end of the reset member 544 is against the upper surface of the upper mounting frame 11;

[0077] The trigger member 541 acts on the response member 542 to move the response member 542 downward, and drives the unloading clamp 543 to move downward. The reset member 544 acts on the response member 542 to move the response member 542 upward, and drives the unloading clamp 543 to move upward.

[0078] In order to facilitate the smooth unloading of the assembled clamping strip 6 and piston 7 , a unloading device 54 is further provided in the present technical solution. The unloading device 54 comprises a trigger member 541 , a response member 542 , an unloading clamping member 543 and a reset member 544 .

[0079] Specifically, the working process of the unloading device 54 is as follows:

[0080] (1) The material moving device moves the assembled clamping strip 6 and piston 7 to the unloading station;

[0081] (2) When the material transfer device moves to the material unloading station, the unloading clamp 543 clamps the upper end of the material picking head 51, and the trigger member 541 triggers the response member 542;

[0082] (3) The response member 542 moves downward under the action of the trigger member 541, and the unloading clamp 543 pulls the assembled clamping strip 6 and piston 7 downward;

[0083] (4) The assembled clamping strip 6 and piston 7 fall into the material discharge hopper 4 under the pulling of the material discharge clamp 543;

[0084] (5) The material transfer device moves to the material taking station, and the reset member 544 acts on the response member 542, so that the response member 542 and the material unloading clamp 543 are reset upward.

[0085] Further explained, the first feeding mechanism 3 includes a loading device, a spacing device 32 and a feeding clamp 33, the feeding clamp 33 is installed at the bottom of the loading device, the piston 7 is loaded to the feeding clamp 33 through the loading device, the spacing device 32 is arranged between the loading device and the feeding clamp 33, and the spacing device 32 is used to open or close the unloading port of the loading device.

[0086] The feeding mechanism in the prior art generally loads the material first, waits for the material to be taken away, and then loads the material next time, which causes waiting time during the loading and feeding process, thereby lengthening the assembly process and is not conducive to improving the assembly efficiency.

[0087] In order to further improve the assembly efficiency of automated assembly, the first feeding mechanism 3 in the present technical solution includes a loading device, a spacing device 32 and a feeding clamp 33. The feeding clamp 33 is installed at the bottom of the loading device. The piston 7 is loaded to the feeding clamp 33 through the loading device. The spacing device 32 is arranged between the loading device and the feeding clamp 33. The spacing device 32 is used to open or close the unloading port of the loading device (not shown in the figure).

[0088] The working process of the first feeding mechanism 3 in this technical solution is as follows:

[0089] (1) The feeding device feeds materials continuously and uninterruptedly;

[0090] (2) When the feeding fixture 33 is in an idle state, the spacer device 32 opens the unloading port of the loading device, so that the piston 7 loads the material from the loading device to the feeding fixture 33;

[0091] (3) When the feeding fixture 33 is in working state, the spacer device 32 closes the unloading port of the loading device and waits for the feeding fixture 33 to be idle, and then repeats step (2).

[0092] In the technical solution of the present invention, the material is blocked by the material isolation device 32, so that the loading of the loading device is no longer restricted by the feeding clamp 33, and the material can be loaded continuously and uninterruptedly. At the same time, when the feeding clamp 33 completes its work, there is no need to wait for the loading device to load the material, and the material can be processed next time immediately, which is beneficial to improving the assembly efficiency of the product assembly equipment.

[0093] Further, the feeding device includes a material guide pipe and a feeding seat 311, the feeding seat 311 is provided with a feeding port 3111 and a feeding port, and the feeding port 3111 is connected with the feeding port;

[0094] The material separation device 32 includes a material separation driving member, a rotating shaft 321 and a material separation member 322. The material separation driving member is used to drive the rotation of the rotating shaft 321. The material separation member 322 is arranged along the length direction of the rotating shaft 321, and the material separation member 322 corresponds to the material discharge port one by one. The material separation driving member drives the rotation of the rotating shaft 321 to drive the material separation device 32 to open or close the material discharge port.

[0095] In one embodiment of the present technical solution, the feeding device includes a material guide pipe and a feeding seat 311, and the piston 7 is fed into the feeding seat 311 through the material guide pipe (not shown in the figure), which has a simple structure and is easy to install.

[0096] The material separating device 32 includes a material separating drive member (not shown in the figure), a rotating shaft 321 and a material separating member 322. The material separating drive member is used to drive the rotating shaft 321 to rotate. The material separating drive member drives the material separating device 32 to open or close the material discharge port by driving the rotating shaft 321 to rotate. The material separating device 32 is simple and reasonable, which can effectively improve the operating reliability of the material separating device 32 and ensure the effective material separation of the material separating device 2.

[0097] Preferably, the loading seat 311 is provided with a plurality of groups of loading ports 3111 and unloading ports, and each group of the loading ports 3111 is communicated with the unloading ports.

[0098] To further explain, a material separation notch 3112 is provided on the side wall of the material loading seat 311 facing the material separation device 32 , and a material separation piece 3221 is provided on the side of the material loading seat 311 , and the material separation piece 321 is fitted and clamped in the material separation notch 3112 .

[0099] In one embodiment of the technical solution, a material separation notch 3112 is provided on the side wall of the material loading seat 311 facing the material separation device 32, and a material separation sheet 3221 is provided on the side of the material separation member 322 facing the material loading seat 311, and the material separation sheet 321 is fitted in the material separation notch 3112. The matching arrangement of the material separation member 322 and the material separation notch 3112 is conducive to the reliability of the material separation and avoids the influence of other components in the product assembly equipment on the material separation process.

[0100] Further, the feeding fixture 33 includes a mounting plate 331, a material pushing assembly 332, a material receiving assembly 333 and a clamping assembly 334. The material pushing assembly 332, the material receiving assembly 333 and the clamping assembly 234 are all mounted on the mounting plate 331, and the material receiving assembly 333 is located below the material pushing assembly 332, and the clamping assembly 234 is located on both sides of the material receiving assembly 333.

[0101] The material pushing assembly 332 can move forward and backward relative to the mounting plate 331, and the material receiving assembly 333 can move up and down relative to the mounting plate 331, and the forward movement of the material pushing assembly 332 drives the upward movement of the material receiving assembly 333, and the backward movement of the material pushing assembly 332 drives the downward movement of the material receiving assembly 333.

[0102] The loading fixture or feeding fixture in the prior art generally realizes the function of transfer. Its working process is generally to receive the material first, wait for the completion of the subsequent process, and then transfer the material to the mechanism of the next process, or the components of the next process take away the material located on the loading fixture or feeding fixture. Whether it is transferring the material to the mechanism of the next process or the components of the next process take away the material located on the loading fixture or feeding fixture, the process must go through the waiting step, which easily leads to a longer assembly process and is not conducive to improving the assembly efficiency of product assembly equipment.

[0103] In the present technical solution, a feeding fixture 33 is proposed, which includes a mounting plate 331, a material pushing assembly 332, a material receiving assembly 333, and a clamping assembly 334. The design of the material pushing assembly 332 and the material receiving assembly 333 is added to the feeding fixture 33, which is conducive to reducing the waiting time during the assembly process of the product assembly equipment and further improving the assembly efficiency of the product assembly equipment. Specifically, the material pushing assembly 332 can move forward and backward relative to the mounting plate 331, and the material receiving assembly 333 can move up and down relative to the mounting plate 331, and the forward movement of the material pushing assembly 332 drives the upward movement of the material receiving assembly 333, and the backward movement of the material pushing assembly 332 drives the downward movement of the material receiving assembly 333.

[0104] The working process of the feeding fixture 33 in this technical solution is as follows:

[0105] (1) The piston 7 is loaded into the push assembly 332 through the loading port of the loading device;

[0106] (2) The material pushing assembly 332 moves forward, driving the material receiving assembly 333 to move upward, and the piston 7 is pushed to the material receiving assembly 333 by the material pushing assembly 332;

[0107] (3) The material pushing assembly 332 moves backward, driving the material receiving assembly 333 to move downward.
