Description

Technical Field

[0001] The utility model relates to the technical field of injection pen assembly equipment, in particular to a detection, rejection, feeding and replenishing device for the pen body assembly of an injection pen. Background Art

[0002] For a reusable injection pen, the injection dose can be adjusted according to actual usage requirements. In the pen body assembly of the injection pen, there is an outer shell body, and an inner shell body is coaxially and rotatably installed in the outer shell body. The current dose scale value can be observed through the window of the outer shell body, and the dose and scale are adjusted by rotating the inner shell body.

[0003] In existing automated detection equipment, in order to improve the detection efficiency, multiple products are usually clamped as a group and synchronously detected and transferred, especially for products with a small volume; as the detection progresses, the products that were full on the feeding tray at the beginning often become less than full due to the rejection of unqualified products, which affects the automated production of subsequent processes.

[0004] In addition, during the assembly process of the injection pen, there is no equipment that can detect the pen body assembly. However, in the actual assembly process, the outer shell body and the inner shell body in the pen body assembly may not be assembled in place, which directly affects the smooth progress of the subsequent assembly. Summary of the Utility Model

[0005] To solve the above problems, the present application provides a detection, rejection, feeding and replenishing device for the pen body assembly of an injection pen with a reasonable structure, so that qualified products can be replenished via a feeding buffer station according to actual needs, effectively ensuring that the material tray is full during discharging and facilitating the smooth progress of subsequent processes.

[0006] The technical solution adopted by the utility model is as follows:

[0007] A detection, rejection, feeding and replenishing device for the pen body assembly of an injection pen includes a working platform. A detection conveyor line, a feeding buffer station, and a discharging conveyor line are sequentially arranged in parallel from front to back on the working platform. A transfer mechanism is installed across the detection conveyor line, the feeding buffer station, and the discharging conveyor line; a material tray is carried and conveyed on the discharging conveyor line, and the tray contains qualified products placed in an orderly manner; qualified products are stored in an orderly manner on the feeding buffer station.

[0008] As a further improvement of the above technical solution:

[0009] The detection conveyor line detects products in groups, and the transfer mechanism clamps and transfers the entire group of products; a single group of products includes multiple products arranged in an orderly manner.

[0010] The feeding buffer station includes a storage vehicle driven by a linear movement component, and a receiving cavity for storing a plurality of qualified products is arranged on the storage vehicle.

[0011] It further includes a collection bin for accommodating unqualified products, and the collection bin is arranged with an upward opening on the outside of the side of the feeding buffer station.

[0012] A trolley is assembled and circulated on the detection conveyor line, and the product is supported by the trolley to circulate on the detection conveyor line.

[0013] The structure of the transfer mechanism is as follows: it includes a translation seat driven by a transfer linear drive module to move, a lifting seat that moves up and down relative to each other is installed on the side of the translation seat through a lifting power component, and a plurality of groups of clamping components are sequentially installed on the lower part of the side of the lifting seat, and the products are correspondingly clamped by the clamping components.

[0014] A height detection mechanism is further arranged between the detection conveyor line and the feeding buffer station. The height detection mechanism is located below the transfer stroke of the transfer mechanism, and the height detection mechanism includes an upwardly arranged acquisition end.

[0015] The height detection mechanism is a laser sensor or a camera assembly.

[0016] The height detection mechanism is installed on the linear movement module.

[0018] Through the setting of the feeding buffer station, in actual production, qualified products can be fed through the feeding buffer station according to actual needs, effectively ensuring that the material tray is full during feeding, and helping the subsequent processes to proceed smoothly;

[0019] The utility model further includes the following advantages:

[0027] The following combines with the attached drawings to illustrate the specific embodiments of the present utility model.

[0028] As Figure 1 shown, the injection pen body assembly detection, rejection, and feeding device of this embodiment includes a working platform. On the working platform, a detection conveyor line 5, a feeding buffer station 7, and a feeding conveyor line 1 are arranged in parallel from front to back. A transfer mechanism 2 is installed across the detection conveyor line 5, the feeding buffer station 7, and the feeding conveyor line 1; the feeding conveyor line 1 carries and conveys a tray 8, and qualified products 9 are orderly placed in the tray 8; qualified products 9 are orderly stored on the feeding buffer station 7.

[0029] In this embodiment, through the setting of the feeding buffer station 7, in actual production, feeding of qualified products can be carried out via the feeding buffer station 7 according to actual needs, effectively ensuring that the tray 8 is full during feeding.

[0030] The detection conveyor line 5 detects the products 9 in groups, and the transfer mechanism 2 clamps and transfers the whole group of products 9; each group of products 9 includes a plurality of products 9 arranged in an orderly manner.

[0031] During use, after the products 9 are detected by the detection conveyor line 5, the transfer mechanism 2 grabs the products 9 from the detection conveyor line 5.

[0032] The feeding buffer station 7 includes a storage cart 70 driven to move by a linear moving component. A receiving cavity for storing a plurality of qualified products 9 is provided on the storage cart 70.

[0033] In this embodiment, the feeding buffer station 7 places qualified products 9 via the receiving cavity. When feeding is required, the products 9 can be clamped and removed from the upper part by the transfer mechanism 2.

[0034] It further includes a collection bin 3 for accommodating unqualified products. The collection bin 3 is arranged with an upward opening on the outside of the side of the feeding buffer station 7.

[0035] When there is a non - compliant product 9, when the transfer mechanism 2 passes above the collection bin 3, it can directly release the clamping of the corresponding product 9, so that the non - compliant product 9 falls into the collection bin 3.

[0036] The inspection conveyor line 5 is equipped with a trolley 6 for transfer. The product 9 is supported by the trolley 6 and transferred on the inspection conveyor line 5.

[0037] The trolley 6 in this embodiment can be similar to the storage trolley 70. A receiving cavity is provided to place the product 9.

[0038] The inspection conveyor line 5 in this embodiment can be a straight conveyor line connected to the previous process, or a rotary conveyor line equipped with a feeding mechanism.

[0039] In this embodiment, according to actual usage requirements, corresponding inspections can be realized by arranging inspection mechanisms on the inspection conveyor line 5. For example, by arranging cameras, the pen body components on the inspection conveyor line 5 are inspected to determine the zero position.

[0040] Such as Figure 2 and Figure 3 As shown, the structure of the transfer mechanism 2 is as follows: it includes a translation seat 23 driven by a transfer linear drive module 21 to move. A lifting seat 24 that moves up and down relative to each other is installed on the side of the translation seat 23 through a lifting power component 22. A plurality of groups of clamping members 25 are sequentially installed on the lower part of the side of the lifting seat 24, and the product 9 is clamped by the clamping members 25 correspondingly.

[0041] During use, the clamping member 25 in the transfer mechanism 2 clamps the product 9 located on the inspection conveyor line 5 in combination with the operation of the lifting power component 22. Then, in combination with the operation of the transfer linear drive module 21, the product 9 is moved from the inspection conveyor line 5 towards the blanking conveyor line 1.

[0042] A height detection mechanism 4 is also provided between the inspection conveyor line 5 and the feeding buffer station 7. The height detection mechanism 4 is located below the transfer stroke of the transfer mechanism 2. The height detection mechanism 4 includes an acquisition end arranged upward. The distance between the bottom end feature of the inner shell and the bottom end of the outer shell in the product 9 is obtained from below by the height detection mechanism 4, providing detection support for the assembly of the inner shell relative to the outer shell.

[0043] In this embodiment, by arranging the height detection mechanism 4 within the transfer stroke of the transfer mechanism 2 and arranging the acquisition end upward, during the blanking process, the product 9 can be detected from below by the height detection mechanism 4, realizing the detection of the height of the structural features of the inner shell at the bottom of the pen body component relative to the bottom end of the outer shell. This not only helps to ensure the reliability of the assembly, but also effectively eliminates operations such as clamping during height detection. The concept is ingenious, the layout is compact, and the practicability is good.

[0044] The height detection mechanism 4 is a laser sensor or a camera assembly that can detect the height distance.

[0045] like Figure 4 As shown, the height detection mechanism 4 is installed on the linear motion module 40 , and can drive the height detection mechanism 4 to move according to actual detection requirements to match the detection requirements of multiple products 9 on the transfer mechanism 2 .

[0046] In this embodiment, a stacking mechanism for the material trays 8 can be arranged across the unloading conveyor line 1, so that when unloading, the material trays 8 can be stacked on the unloading conveyor line 1, and the products 9 can be unloaded at one time after stacking.

[0047] In actual use, qualified products 9 can be reserved on the replenishing buffer station 7 in priority. For example, when the machine is started, the transferring mechanism 2 places the qualified products 9 on the replenishing buffer station 7. In the normal production process, when unqualified products 9 appear, the transferring mechanism 2 places them in the collecting bin 3, and other qualified products 9 are unloaded. After that, the transferring mechanism 2 takes materials from the replenishing buffer station 7 to replenish the corresponding positions.

[0048] The utility model can replenish qualified products through the replenishment buffer station according to actual needs, effectively ensuring that the material tray is full when unloading, and facilitating the smooth progress of subsequent processes.

[0049] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.
