Technical Field

[0001] This utility model belongs to the technical field of assisted reproductive product manufacturing equipment, specifically relating to a carrier sheet assembly device. Background Technology

[0002] Vitrified cryopreservation rods are one of the important auxiliary tools in the field of assisted reproduction, and their production and assembly require high standards. Currently, the assembly of the carrier film and the rod body of vitrified cryopreservation rods mainly relies on manual operation: the operator manually positions the rod body, holds the carrier film to align and insert it, controls the assembly depth based on experience, and then waits for the adhesive to fix it in place.

[0003] This method has the following problems: First, the alignment accuracy is poor, and manual visual alignment is prone to deviation, resulting in the carrier sheet being "misaligned"; second, the assembly depth control is inconsistent, with no unified benchmark, and the depth varies greatly between different operations or batches, which does not meet the product standardization requirements; third, the assembly efficiency is low, with only one product being assembled at a time, which cannot meet the needs of mass production; fourth, the product qualification rate is low, and the above problems combined with human error lead to a high defect rate, increasing production costs and rework workload.

[0022] Example 1

[0023] like Figure 1 As shown, a carrier sheet assembly device according to a first aspect embodiment of the present invention includes a frame, a vitrified cryopreservation rod placement area 2, a vitrified cryopreservation rod carrier sheet placement area 1, and a drive control assembly. The vitrified cryopreservation rod placement area 2 is fixedly installed on the frame and has multiple rod slots for positioning the vitrified cryopreservation rods. The vitrified cryopreservation rod carrier sheet placement area 1 is arranged opposite to the vitrified cryopreservation rod placement area 2 and has multiple carrier sheet positioning slots corresponding one-to-one with the rod slots. The carrier sheet positioning slots are equipped with guide structures. The drive control assembly includes a push cylinder 3, a time delay relay 5, and a position adjuster. The cylinder body of the push cylinder 3 is fixed to the frame, and its piston rod is connected to the vitrified cryopreservation rod carrier sheet placement area 1, which is used to drive the vitrified cryopreservation rod carrier sheet placement area 1 to move toward or away from the vitrified cryopreservation rod body placement area 2. The position adjuster is set on the axial push path of the push cylinder 3, which is used to adjust and limit the movement stroke of the vitrified cryopreservation rod carrier sheet placement area 1 to control the assembly depth of the carrier sheet. The time delay relay 5 is electrically connected to the push cylinder 3, which is used to control the push cylinder 3 to retract after a delay after the carrier sheet reaches a preset depth.

[0024] In the above embodiments, it should be noted that the push cylinder 3 serves as the power source, and the movement stroke is precisely controlled by the position adjuster to ensure consistent assembly depth; the time delay relay 5 allows the adhesive material to fully cure under pressure, improving connection reliability.

[0025] The technical effects achieved by the above embodiments are as follows: through automated driving and precise positioning, the carrier sheet and the vitrified cryopreservation rod are automatically aligned and uniformly assembled, effectively avoiding the phenomenon of "misalignment". The assembly depth deviation is controlled within ±0.2mm, and the product qualification rate is significantly improved. At the same time, multiple products can be assembled at the same time, and the assembly efficiency is more than 5 times higher than that of manual operation, meeting the needs of mass production.

[0026] Example 2

[0027] like Figure 1 As shown, a carrier sheet assembly device includes all the contents of Embodiment 1, and in addition, it also includes detachably mounted rod slots and carrier sheet positioning slots. The number of rod slots is ten, and the number of carrier sheet positioning slots is correspondingly ten. The guide structure is a linear guide rail disposed on both sides of the carrier sheet positioning slot.

[0028] In the above embodiments, it should be noted that the detachable design facilitates quick replacement of different models of positioning slots, and the linear guide rail ensures that the carrier sheet maintains precise alignment during movement.

[0029] The technical effects achieved by the above embodiments are as follows: through the detachable positioning slot and batch layout (10 workstations), flexible production of multiple models and efficient batch operation can be realized, and the changeover time can be controlled within 3 minutes, further improving production flexibility and efficiency; the guide structure effectively prevents offset during the assembly process and ensures alignment accuracy.

[0030] Example 3

[0031] like Figure 1 As shown, a carrier sheet assembly device includes all the contents of Embodiment 1, except that it also includes a sensor for detecting whether the carrier sheet has reached a preset depth. The sensor is connected to a time delay relay 5. The rod slot and the carrier sheet positioning slot are made of 304 stainless steel and polished. The frame is also equipped with a system pressure display 4, a system pressure regulating valve 7 and a power switch 6.

[0032] In the above embodiments, it should be noted that the sensor provides real-time depth feedback and works in conjunction with the time-delay relay to ensure the accuracy and consistency of assembly depth control; the polished 304 stainless steel material provides good corrosion resistance and surface finish, and is easy to clean and maintain; the system pressure display 4 and regulating valve 7 facilitate monitoring and adjustment of pneumatic parameters to ensure stable operation of the cylinder 3.

[0033] The technical effects achieved by the above embodiments are as follows: by linking the signals of sensors and time-delay relays, the control accuracy and automation level of assembly depth are further improved; high-quality materials ensure the durability and hygiene requirements of the device; the pneumatic system monitoring components enhance the reliability and convenience of operation; the overall device has a simple structure and is easy to operate, reducing labor costs and rework rates, and improving production economic efficiency.

[0034] The working principle and usage process of this utility model are as follows: When in use, the operator checks that the air source and power supply of the device are connected normally, and after confirming that the air pressure parameters are appropriate through the system air pressure display 4 and the system air pressure regulating valve 7, turns on the power switch 6; according to the model of the product to be assembled, select the appropriate detachable rod slot and carrier sheet positioning slot, and install them on the vitrified cryopreservation rod placement area 2 and the vitrified cryopreservation rod carrier sheet placement area 1. The changeover process can be completed within 3 minutes.

[0035] Then, the material is loaded: 10 vitrified cryopreservation rods with glue are placed one by one into the rod slots in the rod placement area 2, ensuring that the bottom of the rod is in contact with the bottom of the slot; at the same time, 10 carrier sheets are placed into the carrier sheet positioning slots in the carrier sheet placement area 1, with the marked side of the sheet facing up.

[0036] After loading is complete, pressing the start button activates cylinder 3, which receives a signal and begins operation. Its piston rod drives the vitrified cryopreservation rod carrier sheet placement area 1 towards the vitrified cryopreservation rod body placement area 2. Linear guide rails on both sides of the carrier sheet positioning groove serve as guiding structures, ensuring precise alignment between the carrier sheet and the rod body and preventing misalignment.

[0037] During the movement, a position adjuster (usually a screw and nut mechanism mounted on the piston rod of the push cylinder 3) is used to adjust and limit the travel of the carrier sheet placement area 1, thereby controlling the depth of the carrier sheet inserted into the rod. When the carrier sheet reaches the preset depth, the sensor detects a signal and transmits it to the time delay relay 5. The time delay relay 5 starts timing, and the delay time is set according to the characteristics of the adhesive material (usually 4 seconds). During this period, the push cylinder 3 maintains its position, allowing the carrier sheet and the rod to complete the adhesive positioning under pressure.

[0038] After the delay period ends, the time-delay relay 5 controls the push cylinder 3 to automatically reverse and retract, causing the carrier sheet placement area 1 to reset. The operator can then remove 10 assembled products from the rod placement area 2. The entire assembly cycle takes no more than 15 seconds.

[0039] Through this automated drive and precise control, the device achieves automatic alignment and uniform depth assembly of the carrier sheet and vitrified cryopreservation rod. The assembly depth deviation is controlled within ±0.2mm, the misalignment rate is reduced to below 0.5%, and the product qualification rate is increased to over 98%. At the same time, it can assemble 10 pieces in a single batch, which is more than 5 times more efficient than manual operation, meeting the needs of mass production and multiple flexible models.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
