[0033] The following combines the drawings to illustrate the detailed embodiment of the present utility model.

[0034] As Figure 1As shown in the figure, the detection device for the pen body assembly of the injection pen in this embodiment includes a working platform 1. A material conveying line and a rotary conveying line 2 arranged in parallel with the material conveying line are provided on the working platform 1. A transfer mechanism 8 is installed between the material conveying line and the rotary conveying line 2, and the transfer mechanism 8 transfers the product 10 between the material conveying line and the rotary conveying line 2. Along the conveying direction of the rotary conveying line 2, a torque detection mechanism 3 and a zero position detection mechanism 4 are arranged in sequence.

[0035] In this embodiment, through the material conveying line and the parallel rotary conveying line 2, matching the transfer mechanism 8, the automatic feeding, detection transfer and discharging of the product 10 during the detection process are realized, and the overall layout of the equipment is compact, reasonable and ingenious; during the process of flowing along the rotary conveying line 2, the torque of the product 10 can be detected by the torque detection mechanism 3, and the zero position detection can be carried out by the zero position detection mechanism 4, so as to realize the automatic torque and zero position detection of the pen body assembly of the injection pen.

[0036] The material conveying line includes a feeding conveying line 9 and a discharging conveying line 7 which are connected in a straight line. The feeding conveying line 9 transfers the empty material box to the discharging conveying line 7.

[0037] In this embodiment, the feeding conveying line 9 and the discharging conveying line 7 are connected and arranged on the same straight line, realizing the automatic transfer of the empty material box from the feeding position to the discharging position, and matching the feeding of the product 10 during feeding and the discharging of the product 10 during discharging.

[0038] Material box stacking mechanisms are respectively arranged across the feeding conveying line 9 and the discharging conveying line 7, and stop mechanisms are arranged in front of and behind the material box stacking mechanisms respectively.

[0039] In this embodiment, through the stacking mechanism of the material box, multiple boxes of products 10 can be stacked and fed at one time on the feeding conveying line 9. As the detection production progresses, the feeding conveying line 9 matches the transfer mechanism 8 to feed one box at a time for use; similarly, during discharging, the material boxes can be stacked on the discharging conveying line 7, and the products 10 can be discharged at one time after stacking, which is convenient for the feeding and discharging operations.

[0040] In this embodiment, the material box stacking mechanism can refer to the existing conventional structure, including a jacking mechanism arranged below the conveying line and a supporting mechanism arranged on both sides of the conveying line; during feeding, the jacking mechanism can jack up the stacked material boxes to a preset position, and the supporting mechanism on both sides moves inward to support the second material box below, and then the jacking mechanism descends so that the lowermost material box falls onto the conveying line to realize the feeding of a single box; the discharging process is the opposite. After the jacking mechanism jacks up, the lowermost material box is supported by the supporting mechanism on both sides, and then the jacking mechanism descends to a position lower than the conveying line. The conveying line conveys a new material box to the jacking mechanism, and the jacking mechanism jacks up again to realize stacking.

[0041] In this embodiment, the stop mechanism helps to ensure the reliability of the lifting mechanism when lifting up and down.

[0042] The rotary conveyor line 2 includes two sets of linear conveyor sections 21 arranged in parallel. At both ends of the two sets of linear conveyor sections 21, there are turnover sections 23 respectively equipped via linear drive mechanisms 22; the turnover sections 23 are arranged in parallel with the linear conveyor sections 21, and the turnover section 23 is aligned with one of the sets of linear conveyor sections 21.

[0043] In this embodiment, the rotary conveyor line 2 is connected between loading and unloading, and is connected between the two sets of linear conveyor sections 21 via the turnover section 23. While realizing the transmission of the product 10 and the turnover of the trolley 20 during the detection process, the floor area of the equipment is effectively reduced.

[0044] There is a trolley 20 rotatably arranged on the rotary conveyor line 2, and a cavity for accommodating the product 10 is arranged on the trolley 20.

[0045] During use, the transfer mechanism 8 places the product 10 into the cavity of the trolley 20, or the transfer mechanism 8 takes out the product 10 from the cavity of the trolley 20.

[0046] The trolley 20 located on one set of linear conveyor sections 21 first moves to the turnover section 23 aligned with this linear conveyor section 21, and then the turnover section 23 is driven by the linear drive mechanism 22 to align with another linear conveyor section 21, and the trolley 20 flows from the turnover section 23 to the aligned linear conveyor section 21, so as to realize the turnover of the trolley 20 on the two sets of linear conveyor sections 21.

[0047] As Figure 2 and Figure 3 shown, the structure of the torque detection mechanism 3 is: including supports 33 located on both sides of the rotary conveyor line 2, clamping plates 35 moving towards each other are respectively installed on the supports 33, and concave surfaces for contacting and clamping the outer shell of the product 10 are arranged on the opposite sides of the two clamping plates 35; it also includes a support base 31, and a plurality of linear rotary actuators 32 are sequentially installed on the side of the support base 31. A clamping member one 36 is installed at the downward end of the linear rotary actuator 32, and the upper end of the product 10 is clamped by the clamping member one 36.

[0048] During use, the trolley 20 carrying the product 10 moves between the two sets of supports 33 along with the rotary conveyor line 2. The clamping plates 35 move towards each other to clamp the outer shell of the product 10, and then the linear rotary actuator 32 moves downward. The inner shell exposed upward at the top of the product 10 is clamped by the clamping member one 36. The linear rotary actuator 32 works, applying force to rotate the inner shell relative to the outer shell, and transmitting the torque value information during rotation to the controller to realize the detection of the torque of the product 10.

[0049] In this embodiment, a clamping power source 34, such as a linear power mechanism like a cylinder or an electric cylinder, can be installed on the support 33. The clamping power source 34 drives the clamping plate 35 to move relative to the support 33 to clamp or release the product 10.

[0050] The transfer mechanism 8 includes two groups. One group of the transfer mechanism 8 is used to transfer the product 10 on the material conveying line to the rotary conveying line 2, and the other group of the transfer mechanism 8 is used to transfer the product 10 on the rotary conveying line 2 to the material conveying line.

[0051] Multiple groups of second clamping members 85 are sequentially installed on a single group of the transfer mechanism 8, and multiple products 10 are clamped simultaneously by the multiple groups of second clamping members 85.

[0052] As Figure 4 and Figure 5 shown, the structure of the transfer mechanism 8 is as follows: it includes a translation seat 83 driven to move by a transfer linear drive module 81. A lifting seat 84 that moves up and down relative to each other is installed on the side of the translation seat 83 through a lifting power assembly 82. Multiple groups of second clamping members 85 are sequentially installed on the lower part of the side of the lifting seat 84, and the product 10 is clamped correspondingly by the second clamping members 85.

[0053] It further includes a height detection mechanism 5. The height detection mechanism 5 is located below the transfer stroke of the transfer mechanism 8, and the height detection mechanism 5 includes a collection end arranged upward.

[0054] In this embodiment, the height detection mechanism 5 can obtain the distance between the bottom end feature of the inner shell and the bottom end of the outer shell in the product 10 from below, providing detection support for the assembly of the inner shell relative to the outer shell.

[0055] In this embodiment, the height detection mechanism 5 can be a laser sensor or a camera assembly, as long as it can realize the detection of the height distance.

[0056] By arranging the height detection mechanism 5 below the transfer mechanism 8 and arranging the collection end upward, during the process of the transfer mechanism 8 transferring the product 10, the height detection mechanism 5 can detect the bottom end of the product 10 from below, effectively eliminating operations such as clamping during height detection, with a clever and reasonable concept.

[0057] In this embodiment, the height detection mechanism 5 can also be arranged on a linear module, and the height detection mechanism 5 can be driven to move according to actual detection requirements to match the detection requirements of multiple products 10 on the transfer mechanism 8.

[0058] As Figure 6As shown in the figure, it further includes a feeding buffer station 6, which is located between the blanking conveyor line 7 and the rotary conveyor line 2. The feeding buffer station 6 is arranged in parallel with the blanking conveyor line 7 and is located below the transfer stroke of the transfer mechanism 8. On the feeding buffer station 6, the qualified products 10 that have passed the inspection are reserved in sequence via the trolley 20; it further includes a collection bin 60 for accommodating unqualified products.

[0059] In actual use, the qualified products 10 that have passed the inspection can be preferentially reserved on the feeding buffer station 6. For example, when starting up, the transfer mechanism 8 places the qualified products 10 on the feeding buffer station 6; during the normal production process, when unqualified products 10 appear, the transfer mechanism 8 places them in the collection bin 60, and the other qualified products 10 are blanked. After that, the transfer mechanism 8 takes materials from the feeding buffer station 6 for feeding at the corresponding positions.

[0060] In this embodiment, through the setting of the feeding buffer station 6, it effectively ensures that the material box is full during blanking, which helps the smooth progress of the subsequent processes.

[0061] In this embodiment, the first clamping member 36 and the second clamping member 85 can adopt finger cylinders, which can clamp the product 10 from the upper end.

[0062] In this embodiment, the zero position detection mechanism 4 can be a camera module arranged on the side of the rotary conveyor line 2. The product 10 is imaged by the camera module, and it is observed through the window on the outer housing whether the zero position is displayed, so as to judge the installation of the inner housing relative to the outer housing.

[0063] The present utility model realizes the automatic detection of the pen body assembly of the injection pen, effectively guarantees the detection efficiency and detection effect, helps to ensure the installation of the pen body assembly, and the overall layout of the equipment is compact, reasonable and ingenious, with good practicability.

[0064] In this specification, each embodiment is described in a progressive manner. The key points of each embodiment are the differences from other embodiments. The same and similar parts among the embodiments can be referred to each other.

[0065] The above description is an explanation of the present utility model, not a limitation of the utility model. The scope defined by the present utility model can be seen in the claims. Within the protection scope of the present utility model, any form of modification can be made.
