A turnover packaging board with an irregularly shaped pointed shell

Abstract

This invention relates to the field of gastrointestinal endoscope probe technology, and discloses a turnover packaging plate for irregularly shaped probe shells. During the coating process of gastrointestinal endoscope probes, it is not necessary to clamp each product onto the coating fixture individually; the entire plate of products can be loaded onto the coating fixture at once. The plate-turning method reduces the number of clamping operations and improves coating efficiency. The design of corresponding clearance grooves on the product's peripheral protrusions ensures effective packaging with a consistent packaging direction, without affecting subsequent coating or the required viewing window clearance. Before turning the packaging plate and coating fixture, they are stably connected, and then flipped to achieve product turning. This ensures product stability during turning, preventing internal product detachment and spillage due to insufficient pressure from the hand, slippage during turning, or contact with other objects.

Description

Technical Field

[0001] This invention relates to the field of gastrointestinal endoscope probe technology, and more particularly to coated packaging of gastrointestinal endoscope probes, specifically a turnover packaging board for an irregularly shaped tip shell. Background Technology

[0002] Existing products are mainly used at the tip of gastrointestinal endoscopes, requiring a smooth tip surface. Strict requirements are placed on the appearance of the transparent visual area at the tip, ensuring it is free of stains, scratches, and other defects. To guarantee effectiveness, liquids in the gastrointestinal tract can affect the probe's visibility, so a waterproof coating is necessary.

[0003] Due to the lack of suitable packaging methods and extremely high appearance requirements, the existing use of electrostatic film for packaging easily leads to defects such as dirt and scratches on the products. Furthermore, products packaged with electrostatic film do not have suitable fixtures for cleaning before coating, resulting in poor coating effects and a very low yield rate during turnover and processing.

[0004] Initially, the use of electrostatic film packaging resulted in low efficiency, low yield, and inconvenience. Suppliers used electrostatic film to pack five products at a time, directly into self-sealing bags for shipment. After receiving the goods, users had to remove the products one by one from the film and place them onto the coating fixture. Defective products could not be directly cleaned.

[0005] After the coating is completed, the products are sandwiched in groups of five onto a clean electrostatic film and then packed into self-sealing bags for shipment. Due to the adhesive properties of the film, the products may pile up, causing scratches, abrasions, and other defects. There may also be film marks. Vacuum packaging is not possible, and the products will become dirty during transportation, requiring secondary cleaning.

[0006] Therefore, a special packaging board needs to be designed for this product. Thus, we need to propose a turnover packaging board with an irregularly shaped tip shell, which reduces defects caused by clamping the product during operation and improves work efficiency. Summary of the Invention

[0007] The purpose of this invention is to provide a turnover packaging plate for irregularly shaped tip shells. Through the design of the reversible packaging plate and coating fixture, during the coating process of gastrointestinal endoscope probes, it is unnecessary to individually clamp the products onto the coating fixture; the entire plate of products can be loaded onto the coating fixture at once. The reversible design reduces the number of clamping operations, improving coating efficiency. The design of clearance grooves corresponding to the product's peripheral protrusions ensures effective packaging with a consistent packaging direction, without affecting subsequent coating or the required viewing window clearance. The design of the pushing and locking components ensures a stable connection between the packaging plate and the coating fixture before reversing, allowing for product reversal while maintaining product stability during the reversing process. This prevents products from falling out and spilling due to insufficient pressure from the hand, slippage during reversal, or contact with other objects, thus solving the problems mentioned in the background art.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] 1. This invention, through the design of a shiftable packaging plate and coating fixture, eliminates the need to individually clamp products onto the coating fixture during the coating process of gastrointestinal endoscope probes. Instead, the entire plate of products can be loaded onto the coating fixture at once. By using a shifting plate, the number of clamping operations is reduced, improving the coating efficiency. The design of setting clearance grooves corresponding to the protrusions on the product's periphery ensures effective packaging of the product, and the packaging direction is consistent, without affecting subsequent coating or the required window clearance effect of the product.

[0021] 2. This invention, through the design of the pushing component and the locking component, stably connects the packaging plate and the coating fixture before they are tilted, and then flips them over to achieve product tilting. It also ensures the stability of the product during the tilting process and prevents the internal product from falling off and spilling out due to insufficient pressure from the hand on the packaging plate and the coating fixture, slipping out of the hand when tilting the packaging plate and the coating fixture, or contact with other objects when tilting the packaging plate and the coating fixture.

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Please see Figure 1-11 This invention provides a technical solution: a turnover packaging plate for an irregularly shaped tip shell, comprising a packaging plate 1 and a coating fixture 2 with matching dimensions, facilitating flipping processing between the packaging plate 1 and the coating fixture 2. A protruding plate 101 is connected to the front of the packaging plate 1, the size of which is smaller than that of the packaging plate 1. Multiple first through holes 102, arranged in a matrix and penetrating the packaging plate 1, are formed on the protruding plate 101. An endoscope tip probe is installed at a position corresponding to the first through hole 102. The inner wall of the first through hole 102 has a relief groove 103 corresponding to a protrusion on the side wall of the endoscope tip probe. Specifically, in this embodiment, the inner wall of the first through hole 102 has four annularly spaced... The placement groove 103 has four protrusions on the side of the endoscope probe. The protrusions are installed inside the placement groove 103, which ensures that the product is effectively packaged while maintaining a consistent orientation. The inner wall of the first through hole 102 is provided with a ramp 104 for supporting the bottom of the endoscope probe. The bottom outer wall of the product is pressed against the ramp 104, so that the bottom edge of the product contacts the edge of the ramp 104, preventing scratches on the product. The front of the coating fixture 2 has a second through hole 204 aligned with the first through hole 102. The second through hole 204 is equipped with a positioning post 205 for positioning the endoscope probe. This does not affect the subsequent coating and the required window clearance effect of the product.

[0036] The packaging plate 1 is connected to the side of the limiting mechanism 3. The front side of the coating fixture 2 is provided with a first groove 201 and a second groove 202 respectively. The limiting mechanism 3 is engaged inside the first groove 201. The second groove 202 is equipped with a positioning mechanism 4. The positioning mechanism 4 is equipped with a pushing component 5 and a locking component 6 for locking the limiting mechanism 3 and the positioning mechanism 4.

[0037] The connection between the limiting mechanism 3 and the packaging plate 1 is a detachable connection, and the connection between the positioning mechanism 4 and the coating fixture 2 is also a detachable connection. The specific connection structure can adopt any one of the commonly used existing technologies, without specific limiting, and will not be described in detail here.

[0038] Both the packaging plate 1 and the coating fixture 2 are square in shape. The side length of the coating fixture 2 is 135mm, and the side length of the packaging plate 1 is 109.9-110.1mm. The front of the coating fixture 2 is provided with a snap-fit ​​groove, and the protruding plate 101 is fitted into the inside of the snap-fit ​​groove.

[0039] It is worth noting that both the packaging plate 1 and the coating fixture 2 have beveled corners to facilitate the installation of the packaging plate 1 and the coating fixture 2 during the pouring process, ensuring the correct installation direction.

[0040] The limiting mechanism 3 includes a first fixing block 31 that engages inside the first groove 201. The first fixing block 31 has a receiving cavity inside, which includes a first hole 32, a second hole 33, and a third hole 35 that are sequentially arranged through each other. The inner diameter of the first hole 32 is smaller than the inner diameter of the second hole 33. A ring 36 is slidably installed inside the second hole 33. The inner diameter of the third hole 35 is the smallest and is the same as the diameter of the connecting post 61.

[0041] The outer wall of the ring 36 is integrally formed with a first slider 37, and the inner wall of the second hole 33 is provided with a first groove 34. The first slider 37 is slidably installed inside the first groove 34, and the inner diameter of the ring 36 is less than or equal to the inner diameter of the first hole 32.

[0042] The positioning mechanism 4 includes a second fixing block 41 installed inside the second groove 202. One end of the second fixing block 41 is provided with a first mounting groove 42, and one side of the second fixing block 41 is provided with a second mounting groove 43 that communicates with the first mounting groove 42.

[0043] The coating fixture 2 is also provided with a through hole 203 for connecting the first groove 201 and the second groove 202. The first mounting groove 42, the through hole 203, the first hole 32, the second hole 33, and the third hole 35 are coaxially arranged.

[0044] The locking component 6 will pass through the second mounting slot 43, the through hole 203, and the first hole 32 to enter the interior of the second hole 33.

[0045] The propulsion assembly 5 includes a connecting plate 51 that is slidably installed inside the first mounting groove 42 and the second mounting groove 43. A push rod 52 is connected to one side of the connecting plate 51, and a contact plate 54 is connected to one end of the connecting plate 51 through the second mounting groove 43. An anti-slip layer is provided on the contact plate 54 to facilitate pushing the contact plate 54.

[0046] Pushing the contact plate 54 causes the connecting plate 51 to move closer to the limiting mechanism 3 inside the first mounting groove 42 and the second mounting groove 43. The connecting plate 51 also causes the push rod 52 to move inside the second mounting groove 43, and the push rod 52 causes the locking assembly 6 to move inside the second mounting groove 43.

[0047] The top and bottom of the connecting plate 51 are both connected to the second slider 53. The inner wall of the second mounting groove 43 is provided with a second sliding groove 44. The second slider 53 is slidably installed inside the second sliding groove 44 to ensure the stability of the contact plate 54 during movement.

[0048] The locking assembly 6 includes a connecting post 61 connected to the push rod 52 and slidably installed inside the first mounting groove 42. Multiple ring-shaped equidistant claws 62 are rotatably installed on the outer wall of the connecting post 61. The claws 62 are bent. A support base 63 is installed on the outer wall of the connecting post 61. A rotating shaft 64 is rotatably installed on the support base 63. One end of the claw 62 is connected to the outer wall of the rotating shaft 64. A limiting plate 65 for limiting the rotation angle of the claw 62 is installed on the top of the support base 63.

[0049] When the locking component 6 is fully inserted into the interior of the second hole 33, the claw 62 connected to the outer wall of the connecting column 61 is no longer restricted. The claw 62 opens, and the movable end of the claw 62 moves upward and abuts against the inner wall at the connection between the first hole 32 and the second hole 33, thereby locking the limiting mechanism 3 and the positioning mechanism 4, thus achieving a stable connection between the packaging plate 1 and the coating fixture 2, which increases the stability of the product on the packaging plate 1 and the coating fixture 2.

[0050] An elastic component is provided between the bottom of the claw 62 and the outer wall of the connecting post 61. The elastic component includes a first mounting plate 66 fixed on the connecting post 61 and a second mounting plate 67 aligned with the first mounting plate 66. A spring 68 and a first telescopic rod 69 are connected between the first mounting plate 66 and the second mounting plate 67. A second telescopic rod 610 is rotatably connected between the second mounting plate 67 and the bottom of the claw 62.

[0051] During the opening of the claw 62, under the elastic force of the spring 68, the spring 68 pushes the second mounting plate 67 to move upward, the second mounting plate 67 pushes the second telescopic rod 610 to move upward, and the second telescopic rod 610 deflects. Through the second telescopic rod 610, the claw 62 rotates around the pivot 64 as the rotation center. That is, the movable end of the claw 62 moves upward and abuts against the inner wall at the connection between the first hole 32 and the second hole 33.

[0052] In use, place the product (gastrointestinal endoscope probe) inside the first through hole 102, and make the protrusion on the side of the product engage with the interior of the relief groove 103 to achieve horizontal and reverse positioning of the product and prevent the product from deflecting. The bottom outer wall of the product is pressed against the ramp 104 to achieve contact between the bottom edge of the product and the edge of the ramp 104 to prevent scratching the product. After installing the product in each position of the first through hole 102 in sequence, the packaging plate 1 is covered with the product, and then the coating fixture 2 is covered on the packaging plate 1.

[0053] This allows the positioning post 205 in the second through hole 204 on the coating fixture 2 to be inserted into the product's viewing window, thus achieving a clearance treatment of the viewing window. This does not affect the appearance inside the hole, preventing scratches or wear during transportation and handling, and also achieving product positioning. In summary, this achieves multi-directional positioning of the product, ensuring that the product is placed in the packaging plate in the same direction, so that the product's viewing window will not come into contact with the packaging plate 1 no matter how it shakes. Furthermore, all products can be transferred to the coating fixture 2 by tilting the plate, completely eliminating the need for manual individual clamping and improving coating efficiency.

[0054] Then, the packaging board 1 is fixed together with the coating fixture 2, specifically:

[0055] After the packaging plate 1 and the coating fixture 2 are closed, the limiting mechanism 3 is located inside the first groove 201. Then, the contact plate 54 is pushed, and the contact plate 54 drives the connecting plate 51 to move closer to the limiting mechanism 3 inside the first mounting groove 42 and the second mounting groove 43. The connecting plate 51 drives the push rod 52 to move inside the second mounting groove 43. The push rod 52 drives the locking component 6 to move inside the second mounting groove 43. The locking component 6 will pass through the second mounting groove 43, the through hole 203, and the first hole 32 to enter the interior of the second hole 33. As the locking component 6 enters the interior of the second hole 33, the claw 62 connected to the outer wall of the connecting post 61 loses its restriction.

[0056] Under the elastic force of spring 68, spring 68 pushes the second mounting plate 67 to move upward, the second mounting plate 67 pushes the second telescopic rod 610 to move upward, and the second telescopic rod 610 deflects. Through the second telescopic rod 610, the pawl 62 rotates around the pivot 64. That is, the movable end of the pawl 62 moves upward and abuts against the inner wall at the connection between the first hole 32 and the second hole 33, thereby locking the limiting mechanism 3 and the positioning mechanism 4. This achieves a stable connection between the packaging plate 1 and the coating fixture 2, which increases the stability of the product on the packaging plate 1 and the coating fixture 2. This prevents the product from falling out and spilling out due to insufficient pressure from the hand on the packaging plate and the coating fixture, slipping out of the hand when the packaging plate and the coating fixture are tilted, or contact with other objects when the packaging plate and the coating fixture are tilted.

[0057] Then, the packaging plate 1 and the coating fixture 2 are flipped 180 degrees to perform a flipping process, moving the product from the packaging plate 1 to the coating fixture 2, and the contact plate 54 is pushed forward. The connecting plate 51 and the push rod 52 drive the connecting column 61 to continue moving towards the third hole 35, and the end of the connecting column 61 enters the interior of the third hole 35. During this process, the top of the claw 62 moves along the inner wall of the second hole 33 until the outer wall of the claw 62 abuts against the inner wall of the ring 36 and pushes the ring 36 to move. When the first slider 37 moves to the inner side wall of the first slide groove 34, the ring 36 stops moving, but the connecting column 61 continues to move with the claw 62.

[0058] At this time, under the pressure of the inner wall of the ring 36, the outer wall of the pawl 62 begins to rotate, that is, the end of the pawl 62 retracts inward until the top of the pawl 62 is in contact with the inner wall of the ring 36, completing the retraction of the pawl 62. Then the contact plate 54 retracts (that is, the contact plate 54 moves in the opposite direction), driving the locking assembly 6 (connecting post 61 and pawl 62) to move. Under the action of the friction between the pawl 62 and the ring 36, the ring 36 will also move. When the ring 36 moves to the point of being in contact with the inner wall of the second hole 33, it stops moving. However, under the action of the contact plate 54, the connecting post 61 and the pawl 62 will continue to move, so that the pawl 62 gradually engages with the inner wall of the ring 36. The inner wall of ring 36 detaches, and the end of claw 62 enters the interior of the first hole 32. The outer wall of claw 62 abuts against the inner wall of the first hole 32, thus limiting claw 62 through the inner wall of the first hole 32 and keeping claw 62 in a continuously retracted state until the locking component 6 is pulled back into the interior of the first mounting groove 42. The connection between the limiting mechanism 3 and the positioning mechanism 4 is canceled, that is, the connection between the packaging plate 1 and the coating fixture 2 is canceled. Then the packaging plate 1 is removed, and the coating process of the product can begin. After the coating is completed, the above operation is repeated, the plate is flipped again, and the product is put back into the packaging plate 1 for inspection, packaging, vacuuming, and shipment to the customer.

[0059] After using packaging plate 1, only the plating fixture 2 is needed for the plate flipping and coating process, while packaging plate 1 is used for everything else, which is convenient and fast. The product positioning design in packaging plate 1 and plating fixture 2 ensures that the product orientation is always consistent, preventing the plating of the wrong area, and the whole process is convenient and will not cause too many defects.

[0060] Although embodiments of the 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 invention, the scope of which is defined by the appended claims and their equivalents.
