Description

Technical Field

[0001] This utility model belongs to the field of automated assembly technology of insulin pens, and relates to a reversing mechanism, and more particularly to a reversing and positioning mechanism. Background Technology

[0002] Many connector materials require processing or assembly at both ends during the assembly process. For example, the connector body in an insulin pen is formed by assembling two shell parts. One part is set on a carrier, and the other part is taken from the material and assembled on one of the parts of the carrier to form the complete shell of the connector body. Then, the whole needs to be turned around so that the bottom is facing upwards for other processes such as needle assembly and glue application. In addition, under some working conditions, the connector body may need to be turned around repeatedly to meet the requirements of other processes.

[0003] Taking the connector body as an example, the structures of its two opposite ends that require processing are completely different. Therefore, two different sets of carriers are needed to adapt to the transfer of the connector body after reversal. In addition, with the setting of two different sets of carriers and the transfer line of the carrier, the mechanism that operates the reversal needs to make a large displacement after picking up and reversing the material or dock with other feeding mechanisms to transfer the connector body to the new carrier. This results in the formation of too many transfer stations or transfer mechanisms, making the overall production line not streamlined and production efficiency not improved. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems in the existing technology by proposing a reversing and switching mechanism. It solves the technical problems of complex and inefficient existing reversing station structures.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] A reversing and shifting mechanism includes a picking claw and a carrier arranged opposite to each other. The picking claw is connected to a drive component that can drive it to make linear reciprocating motion in both the horizontal and vertical directions. The carrier has a protruding limiting part one and a recessed limiting part two, which are respectively used to position the opposite ends of the material. The picking claw is connected to a drive component that can drive the picking claw to rotate 180° circumferentially.

[0007] This reversing and shifting mechanism consists of two parts: a reversing mechanism and a carrier.

[0008] The carrier is designed with a limiting part one and a limiting part two. The protruding limiting part one and the recessed limiting part two can respectively carry the material before the positioning and the material after the positioning and changing.

[0009] In addition, the reversing part includes a picking claw, which can move vertically relative to the carrier and horizontally relative to the carrier. The picking claw itself is also connected to a drive unit that drives it to flip. This picking claw picks up material from the first limiting part on the carrier by moving up and down, and then moves to the second limiting part by moving horizontally and vertically. At the same time, it can also flip during the position switching process to realize the reversal of the material. All the mechanisms work together and have high stability.

[0010] This design eliminates the need to change the carrier after the material is redirected; the material can directly switch positions on the same carrier. This results in a small movement range for the redirection mechanism and a streamlined cycle time. Furthermore, if the material direction needs to be changed again or repeatedly in the future, the same redirection part only needs to be set on one side of the same conveyor line, and the reverse switching can be performed. This redirection and switching mechanism has high adaptability, simplifying the structure while improving efficiency.

[0011] In the aforementioned reversing and shifting mechanism, the first limiting part and the second limiting part are arranged at intervals along the horizontal direction, and the picking claw is located above the carrier and can move above the first limiting part or the second limiting part by moving relative to the carrier in the horizontal direction.

[0012] In this application, the limiting part one and the limiting part two are arranged at a certain distance along the horizontal direction. The moving direction of the picking claw in the horizontal direction is the same as the arrangement direction of the limiting part one and the limiting part two. At the same time, the horizontal moving distance of the picking claw corresponds to and matches the limiting part one and the limiting part two. That is, the picking claw can switch between the limiting part one and the limiting part two in the horizontal direction. In addition, the picking claw can move back and forth in the vertical direction, which can realize the arbitrary grabbing of material on the limiting part one or the limiting part two and transferring it to another place. The picking claw designed in this way is simple to move and highly efficient.

[0013] In the aforementioned reversing mechanism, the carrier includes a carrying platform and a base. At least two mounting slots are provided on the carrying platform along the horizontal direction. The first limiting part and the second limiting part are both independent modular structures and are fixed to the carrying platform by being embedded in the mounting slots.

[0014] This carrier includes a carrying platform and a base. The base is adapted to the conveyor line and can drive the overall movement of the base. The carrying platform is designed with mounting slots for mounting limit part one and limit part two. Both limit part one and limit part two adopt a modular design and can be customized individually. They can be modified and adapted according to the material, achieving the effect of changing materials without changing the line, which can greatly improve adaptability.

[0015] In the aforementioned reversing and switching mechanism, the limiting part one includes a mating block one, on which a ring-shaped receiving block protrudes, and the center of the receiving block has a through hole, which extends from the top surface of the receiving block to the bottom surface of the mating block one to form an avoidance groove.

[0016] In one of the aforementioned reversing and shifting mechanisms, the socket block is provided with a limiting notch and / or positioning protrusion on its side for circumferential engagement with the material.

[0017] In the aforementioned reversing and shifting mechanism, the second limiting part includes a second mating block, the second mating block having a limiting groove for accommodating materials, and the groove wall of the limiting groove having a recessed groove communicating with the limiting groove.

[0018] In the aforementioned reversing and shifting mechanism, the reversing and shifting mechanism includes a slide cylinder one and a slide cylinder two. The slide cylinder one is horizontally oriented, and the slide cylinder two is connected to the slide of the slide cylinder one and is vertically oriented. A back plate is fixed on the slide of the slide cylinder two. The driving component is a rotary cylinder, which is mounted on the back plate. The picking claw is fixed on the rotating end of the rotary cylinder.

[0019] The vertical and horizontal movements of this picking claw are driven by a slide cylinder. The slide cylinder has a single stroke, with only an extension limit position and a retraction limit position. The two limit positions correspond to the distance between the first and second limit parts on the carrier. This driving method is simple, efficient, and the overall movement stability of the slide cylinder is extremely high.

[0020] The material handling claw of this application only needs to switch between two position states, so the driving component is designed as a rotary cylinder, which can simplify the driving of the material handling claw to rotate 180 degrees forward or 180 degrees backward, resulting in high efficiency.

[0021] In the aforementioned reversing and shifting mechanism, the picking claw includes a two-finger cylinder and two claw blocks. The two claw blocks are respectively fixed on the clamping blocks of the two-finger cylinder and moved symmetrically by being driven by the two-finger cylinder. The two-finger cylinder is fixed on the rotating end of the rotary cylinder, and the center of symmetrical movement of the two clamping blocks coincides with the rotation center of the rotating end.

[0022] The two claw blocks of this material-grabbing claw are driven synchronously to move closer or further away by a two-finger cylinder. At the same time, the moving center of the two claw blocks is aligned with the rotation center of the rotary cylinder. This allows the material to maintain stable circumferential rotation when it is being gripped, without eccentricity, thus enabling stable reversal and repositioning.

[0023] In the aforementioned reversing and switching mechanism, two stop members are fixed on the back plate near the rotary cylinder attachment. The two stop members are located on opposite sides of the rotating end of the rotary cylinder. A retaining member is fixed on the rotating end. The rotating end is restricted to a rotation range of 180 degrees by the retaining member abutting against the two stop members.

[0024] By designing a stop on the rotary cylinder and adding a stop on the back plate, the picking claw can maintain a stable 180-degree rotation to achieve reversal.

[0025] Compared with existing technologies, the advantages of this product are:

[0026] 1. The material in this application does not need to change the carrier after reversing. The material can directly switch positions on the same carrier, which makes the movement range of the reversing mechanism small and the cycle time simple. At the same time, if the material direction needs to be changed again or repeatedly, the same reversing part only needs to be set on one side of the same conveyor line and the reverse switching can be performed. This reversing and switching mechanism has high adaptability and improves efficiency while simplifying the structure.

[0027] 2. The base of this carrier is designed to be compatible with the conveyor line and can drive the overall movement of the base. The bearing platform is designed with mounting slots for mounting limit part one and limit part two. Both limit part one and limit part two adopt a modular design and can be customized individually. They can be modified and adapted according to the material, achieving the effect of changing materials without changing the line, which can greatly improve adaptability. Attached Figure Description

[0034] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0035] like Figures 1-5 The diagram illustrates a reversing and repositioning mechanism comprising two parts: a reversing part and a carrier 2. The carrier 2 is mounted on the conveyor line and moves with the conveyor line to various workstations. The reversing part is located on one side of the conveyor line. The reversing part and the carrier 2 combine to complete the reversing and repositioning operation of the material, i.e., the connector body. During the reversing and repositioning process, the carrier 2 remains stationary while the reversing part moves relative to the carrier 2. The carrier 2 is designed with a first limiting part 3 and a second limiting part 4. The first limiting part 3 and the second limiting part 4 are customized to fit the shape and contour of both ends of the actual material. Both ends of the material can have a corresponding and fixed limiting part 3 or the second limiting part 4 on the carrier 2. The specific structure of the first limiting part 3 and the second limiting part 4 will be described below. This design eliminates the need to replace the carrier 2 after the material is reversed, significantly simplifying the original production line structure and reducing the time required to change conveyor lines, thereby improving efficiency. The reversing section includes a picking claw 1, which is connected to a tilting cylinder and is mounted on a two-way drive assembly. The two-way drive assembly includes a mechanism to drive the picking claw 1 to reciprocate vertically and horizontally. In this way, the picking claw 1 descends vertically to pick up material from the first limiting part 3, then rises vertically and moves horizontally to the second limiting part 4. Before descending to the second limiting part 4, it can be tilted to change the material's direction. This design results in a small movement range and a streamlined cycle time. Furthermore, if the material direction needs to be changed again or repeatedly, only the same reversing section needs to be located on one side of the same conveyor line, and the direction can be reversed. This reversing mechanism has high adaptability, simplifying the structure while improving efficiency.

[0036] The specific structure of carrier 2 is as follows: Carrier 2 includes a carrying platform 21 and a base 22. The base 22 is adapted to the conveyor line and can drive the overall movement of the base 22. The base 22 has guide wheel seats and connecting plates that connect to the conveyor line. The carrying platform 21 is fixed to the connecting plate, and the carrying platform 21 is horizontally positioned with an overall height higher than the overall height of the base 22, protruding from the top. This design allows for unobstructed movement and easy repositioning. Four mounting slots 211 are arranged side by side at intervals on the carrying platform 21, which are called slot 1, slot 2, slot 3, and slot 4 from left to right. The spacing between slots 1 and 2 is the same as the spacing between slots 3 and 4. Both limiting parts 3 and 4 are independent modular structures, and are fixed to the support platform 21 by being embedded in the mounting slot 211. Limiting parts 3 are embedded at positions 2 and 4, and limiting parts 4 are embedded at positions 1 and 3. There are two picking claws 1 used for reversing, with the spacing between the two picking claws 1 being the same as the spacing between positions 2 and 4. The two picking claws 1 are in a linked state, meaning that the connector bodies on limiting parts 3 at positions 2 and 4 can be simultaneously reversed and moved to limiting parts 4 at positions 1 and 3, resulting in high design efficiency. It should be noted that after the modular limiting parts 3 and 4 are embedded in the mounting slot 211, they still need to be further fixed to the support platform 21 using detachable positioning components such as bolts to increase stability. Preferably, the mounting slot 211 has a circular outline. The limiting part 3 includes a frustum-shaped mating block 31. A ring-shaped socket block 32 protrudes from the mating block 31. The socket block 32 has a through hole at its center, which extends from the top surface of the socket block 32 to the bottom surface of the mating block 31, forming a clearance slot 33. Further, symmetrical positioning protrusions 35 protrude laterally from the socket block 32. The upper end of the positioning protrusions 35 has a guide slope for guiding the connector body into place. Simultaneously, two symmetrical limiting notches 34 are provided laterally on the socket block 32 perpendicular to the two positioning protrusions 35. The limiting notches 34 extend upward to the top of the socket block 32, serving to avoid the clips on the connector body and simultaneously forming a circumferential positioning barrier with the clips, thus improving the stability of the material. Bolt holes are provided on the mating block 31 for bolts to pass through and secure it to the mounting slot 211. A positioning hole 36 is also provided on the mating block 31, and a hole corresponding to the positioning hole 36 is provided in the mounting groove 211. When installing the limiting part 3, the orientation of the positioning protrusion 35 and the limiting notch 34 can be quickly adjusted by aligning the positioning hole 36 with the hole in the mounting groove 211 to achieve rapid installation. Preferably, the limiting part 4 includes a mating block 41, which has a limiting groove 42 for accommodating materials. A recessed groove 43 communicating with the limiting groove 42 is provided on the groove wall of the limiting groove 42. Similarly, the limiting part 4 also has the positioning hole 36 to achieve rapid installation.

[0037] The drive mechanism for the picking claw 1 includes a sliding cylinder 6 and a sliding cylinder 7. Sliding cylinder 6 is horizontally oriented, while sliding cylinder 7 is connected to the sliding surface of sliding cylinder 6 and is vertically oriented. A back plate 8 is fixed to the sliding surface of sliding cylinder 7. The drive component 5 is a rotary cylinder, with two rotary cylinders fixed side by side on the back plate 8. The rotating end of the rotary cylinder extends horizontally towards the carrier 2, and a mounting platform is formed on the rotating end. A picking claw 1 is fixed at each mounting platform. The vertical and horizontal movements of the picking claw 1 are driven by the sliding cylinder. The sliding cylinder has a single stroke, with only an extension limit position and a retraction limit position. The two limit positions correspond to the distance between the limiting part 3 and the limiting part 4 on the carrier 2. This drive is simplified, efficient, and the overall movement stability of the sliding cylinder is extremely high. The material handling claw 1 of this application only needs to switch between two position states, so the drive component 5 is designed as a rotary cylinder, which can simplify the drive of the material handling claw 1 to rotate 180 degrees forward or reverse 180 degrees, resulting in high efficiency.

[0038] The material gripper 1 includes a two-finger cylinder 12 and two gripper blocks 11. The ends of the two gripper blocks have semi-circular recesses adapted to the material, which merge to form a circle for gripping the material. The two gripper blocks 11 are respectively fixed to the gripper blocks of the two-finger cylinder 12 and driven symmetrically by the two-finger cylinder 12. The two-finger cylinder 12 is fixed to the rotating end 51 of the rotary cylinder, and the center of symmetrical movement of the two gripper blocks coincides with the rotation center of the rotating end 51. This ensures that the material maintains stable circumferential rotation during gripping and rotation, preventing eccentricity and allowing for stable reversal and repositioning. Two stoppers 9 are fixed on the back plate 8 near the rotary cylinder. Their specific positions can be adjusted according to actual needs; theoretically, they only need to ensure that the horizontally arranged gripper blocks remain horizontal after flipping and repositioning. Two stoppers 9 are located on opposite sides of the rotating end 51 of the rotary cylinder. A stopper 52 is fixed on the rotating end 51. The rotating end 51 is restricted to a rotation range of 180 degrees by the stopper 52 abutting against the two stoppers 9. This design ensures that the rotary cylinder drives the rotation to rotate stably.

[0039] This reversing and switching mechanism also includes a detection component, which includes a bracket and two detection elements 10. The two detection elements 10 correspond to positions 1 and 3 respectively and are used to detect whether the limiting member 4 has the connector body after reversal. If there is a shortage of material, it can be replenished.
