Description

Technical Field

[0001] The present invention relates to the technical field of medical device production equipment, and in particular to a material taking auxiliary mechanism. Background Art

[0002] In the production process of various medical consumables, it is often necessary to take out the consumable parts from the trays used to hold them and transfer them to specific workstations for cleaning / bonding and curing / assembly. In order to maximize the use of tray space, improve the tray carrying capacity and thus increase the transportation volume of consumable parts, reduce the number of trays required and thus reduce the transportation frequency of consumable parts, the parts storage positions of the trays currently used are densely and compactly arranged, and the distance between two adjacent storage positions is relatively close.

[0003] Obviously, the current tray structure design will bring the following problems: the dense arrangement of accessories placed in the tray makes the distance between accessories too small, the restriction and restriction of the tray on the accessories makes it difficult for the transfer mechanism to obtain accessories, and the overly dense accessories are not conducive to transferring them to certain specific workstations. For this problem, a concept of obtaining accessories has been proposed: obtaining accessories in batches in succession, specifically, allowing the transfer mechanism to select accessories from the tray at intervals each time, that is, the placement positions of the accessories obtained later and the placement positions of the accessories obtained earlier are arranged alternately.

[0004] To implement the above concept, on the one hand, it is necessary to optimize and improve the transfer device belonging to the transfer mechanism so that the transfer mechanism has the function of obtaining accessories in batches; on the other hand, the material tray must cooperate with each material picking action of the transfer mechanism, that is, it can control the material tray according to the sequential material picking actions of the transfer mechanism. The position of the accessories selected by the material tray can be changed in sequence and in a targeted manner. The opening of the material position to which the selected accessories belong, so that the transfer mechanism can obtain the accessories from the material position with a larger opening each time, so as to reduce the difficulty of obtaining the selected accessories and avoid material picking failure. Summary of the invention

[0005] In view of this, it is necessary to provide a material taking auxiliary mechanism for restraining or loosening the material in the material tray. The material taking auxiliary mechanism can selectively control the opening size change of the material tray material placement position by adapting and connecting with the material tray, so that the accessories in the selected material placement position are loosened. Finally, the material taking auxiliary mechanism can loosen the restrained accessories on the material tray in batches, so that the transfer mechanism can obtain the accessories in batches. Each time the transfer mechanism obtains an accessory, it takes away the accessories in the material placement position with an enlarged opening in the material tray, and the accessories in the material placement position with a reduced opening are taken away in the subsequent transfer and retrieval action.

[0006] The material picking auxiliary mechanism provided by the present invention includes loosening parts that are distributed in rows and can move relative to the material tray, and have loosening openings located on the sides of the loosening parts; the loosening openings can match the material placement positions of the material tray one by one, and the loosening parts can be grouped and moved in an orderly manner and change the openings of the corresponding loosening openings, so that the material placement positions are grouped and moved in an orderly manner following the loosening parts that are in motion and change their own openings.

[0007] In one embodiment, the material tray includes material partitions arranged in rows and at intervals, and the material placement positions are formed on the sides of the material partitions; when the material picking auxiliary mechanism is adapted and connected to the material tray, the material loosening piece can be connected to the material partitions matching therewith; the material loosening piece can drive the material partitions matching therewith to move through its own movement, so as to change the opening of the material placement positions, and the matching material placement positions and the material loosening openings have the same opening change trend.

[0008] With such an arrangement, the opening change control of the material placement position is more convenient, and the opening change can be carried out synchronously in response to the movement of the loosening piece, and if the partition part moves to increase the opening of the loosening opening on one side thereof, then the opening of the loosening opening on the other side of the partition part means that the accessories in the material placement position of the loosening opening with a smaller opening can be better constrained, while the accessories in the material placement position of the loosening opening with a larger opening can be better loosened.

[0009] In one embodiment, the loosening opening includes odd-position loosening openings and even-position loosening openings, and the odd-position loosening openings and the even-position loosening openings are arranged alternately one by one; the loosening piece can select part or all of one of the odd-position loosening openings and the even-position loosening openings in turn and expand the opening of the selected target, and simultaneously expand the opening of the material placement position matching the selected target.

[0010] With such arrangement, the odd-position material levels and even-position material levels corresponding to the odd-position loose material openings and the even-position loose material openings in the material tray can be opened larger in sequence, and the transfer mechanism can thereby obtain the odd-position accessories and the even-position accessories from the material tray in sequence.

[0011] In one embodiment, the loosening piece includes a main loosening piece and an auxiliary loosening piece which are arranged alternately one by one, and each odd-position loosening opening and each even-position loosening opening are formed between the main loosening piece and the auxiliary loosening piece which are arranged adjacently; the main loosening piece and the auxiliary loosening piece can tilt in opposite directions so that the odd-position loosening opening and the even-position loosening opening on both sides of any non-end loosening piece can change their respective openings inversely, and the so-called non-end means: excluding the loosening piece corresponding to the end of the material tray, that is, excluding the head end among the multiple loosening pieces and other loosening parts of the two individuals at the end, these non-end loosening parts can correspond one by one to other material partitioning parts in the material tray except the head end partitioning part and the end material partitioning part; when the material picking auxiliary mechanism is adapted to connect the material tray, the main loosening part and the auxiliary loosening part are respectively connected to the first material partitioning part and the second material partitioning part of the material tray, and the main loosening part and the auxiliary loosening part drive the first material partitioning part and the second material partitioning part to tilt mutually through mutually tilting activities, so that the odd-position loosening opening and the even-position loosening opening change their respective openings in opposite trends.

[0012] With such arrangement, the opening change of each loosening opening is controlled jointly by a main loosening member and an auxiliary loosening member adjacent to the main loosening member used to form the loosening opening, and another loosening opening adjacent to the loosening opening can synchronously change its opening in the opposite direction.

[0013] In one embodiment, a plurality of main loosening parts can move synchronously and simultaneously switch the opening sizes of a plurality of odd-position loosening openings; and / or a plurality of auxiliary loosening parts can move synchronously and simultaneously switch the opening sizes of a plurality of even-position loosening openings.

[0014] With such arrangement, the opening of the odd-position loosening opening is increased and the opening of the even-position loosening opening is decreased simultaneously, or the opening of the odd-position loosening opening is increased and the opening of the even-position loosening opening is decreased simultaneously.

[0015] In one embodiment, the material picking auxiliary mechanism also includes a supporting component and an adjusting component, wherein at least part of the material loosening parts can be movably installed on the supporting component, and the adjusting component is movably connected to the individual material loosening parts movably installed on the supporting component, and can repeatedly generate a first displacement and a second displacement, and through the first displacement and the second displacement, the individual material loosening parts movably installed on the supporting component can be driven to repeat the movement in an orderly manner, so as to repeatedly open and close the corresponding material loosening opening.

[0016] In one embodiment, the loosening parts include main loosening parts and auxiliary loosening parts that are alternately arranged one by one, and odd-position loosening openings and even-position loosening openings are formed on both sides of each non-end loosening part, and each loosening opening is formed between adjacent main loosening parts and auxiliary loosening parts; the adjustment component can drive multiple individuals of at least one of the main loosening parts and the auxiliary loosening parts to perform positive and reverse tilting activities relative to multiple individuals of the other item through the first displacement and the second displacement respectively, so as to change the opening of the odd-position loosening opening and the even-position loosening opening inversely.

[0017] With such arrangement, the adjusting component can orderly expand the opening of the odd-position loosening opening or orderly expand the opening of the even-position loosening opening by orderly producing the first displacement and the second displacement. The opening change of the odd-position loosening opening is opposite to the opening change of the even-position loosening opening. In this way, the accessories in the odd-position material position or the even-position material position can be orderly loosened.

[0018] In one embodiment, the adjustment component includes a first adjustment unit and a second adjustment unit, and the main loosening member and the auxiliary loosening member are movably mounted on the supporting component and are movably connected to the first adjustment unit and the second adjustment unit, respectively; the adjustment component enables the first adjustment unit to move relative to the second adjustment unit in a first direction through a first displacement, and enables the first adjustment unit to move relative to the second adjustment unit in the opposite direction of the first direction through a second displacement.

[0019] With this arrangement, the action rules and trajectory of the first adjustment unit and the second adjustment unit are simple, the difficulty of action control is lower, and the space occupied by the relative activities of the first adjustment unit and the second adjustment unit is less, thereby reducing the body size and layout inconvenience of the material picking auxiliary mechanism.

[0020] In one embodiment, the first adjusting unit and the second adjusting unit are respectively connected to the ends of the main loosening part and the auxiliary loosening part pointing to the same direction. The two are arranged side by side and can produce relative movement having a component along the arrangement direction of the main loosening part; the adjusting component also includes a swinging rotating part, which is respectively rotatably connected to the first adjusting unit and the second adjusting unit; the material picking auxiliary mechanism also includes a driving component connected to the first adjusting unit or the second adjusting unit, and the driving component can drive the first adjusting unit or the second adjusting unit to perform a first displacement and a second displacement in opposite directions of movement in sequence.

[0021] With such arrangement, the activities of the main material loosening member and the auxiliary material loosening member are controlled by the first adjusting unit and the second adjusting unit respectively, and the action switching of the material loosening member and the change of the opening of the material loosening port are more orderly, and it is not easy to have chaotic actions; and the power transmission path of the material picking auxiliary mechanism is simpler and more efficient, and the driving component only needs to drive one of the two adjusting units, and then it can output power to the other adjusting unit through the swing transmission member.

[0022] In one embodiment, the adjustment component includes a plurality of first adapter parts that are arranged in a row and correspond one-to-one to the loose material pieces, one end of the loose material piece protrudes from the supporting component, and the other end is rotatably connected to the adjustment component through the corresponding first adapter part; the supporting component includes a plurality of second adapter parts that are arranged in a row and correspond one-to-one to the loose material pieces, and the middle parts of the two ends of the loose material piece are rotatably installed on the supporting component through the corresponding second adapter parts.

[0023] With such arrangement, the adjustment component drives the loose material to move through the lever principle, the movement trajectory and movement amplitude of the loose material are determined, and the connection and installation stability of the loose material are higher. The reliable structure is conducive to long-term use, the loose material responds to power more quickly, and is less prone to failure.

[0024] In one embodiment, there are multiple loosening pieces, each of which has adjacent odd-position loosening openings and even-position loosening openings on both sides, and an odd-position loosening opening and an adjacent even-position loosening opening are formed between any two adjacent loosening pieces; each loosening piece can change the openings of the odd-position loosening openings and the even-position loosening openings on both sides thereof inversely through tilting movement; when the material picking auxiliary mechanism is adapted to be connected to the material tray, multiple loosening pieces can be connected to the first material partition part or the second material partition part of the material tray, and tilt in the same orientation to drive the matching material partition part to move, so that the two material placement positions on both sides of the material partition part change their openings inversely.

[0025] With such arrangement, each material loosening piece can control the opening changes of the two material loosening openings located on both sides thereof. As long as the material loosening piece tilts to one side, the opening of the material loosening opening on the tilted side will inevitably be reduced, while the opening of the material loosening opening on the other side will be expanded. Therefore, it can achieve the purpose of controlling the opening changes of more material placement positions with fewer material loosening pieces, further simplifying the structure of the material taking auxiliary mechanism.

[0026] In one embodiment, the material picking auxiliary mechanism also includes a lifting component, and the material loosening member can respond to the power output of the lifting component and perform reciprocating lifting and lowering motion to synchronously detach from or connect to all or part of the material separating portion of the material tray.

[0027] In one embodiment, there are multiple loosening pieces distributed in rows, and the loosening pieces are used to be connected one-to-one with the material partitioning parts of the material tray. The loosening pieces can drive the material partitioning parts to move in the same orientation through tilting movements, and make the loosening openings and material placement positions change their opening sizes with the same changing trend.

[0028] The material taking auxiliary mechanism provided by the present invention can loosen the materials distributed in rows on the material tray according to the odd-numbered and even-numbered groups, so that the transfer mechanism can obtain the materials in two batches. If the transfer mechanism obtains the odd-numbered materials first, the even-numbered materials are in a constrained state, and vice versa. In this way, the batch acquisition of materials can be more orderly, and the materials in a certain material placement position will not be omitted, or the transfer mechanism will not be able to obtain the materials in a certain material placement position. Compared with the spacing between the material placement positions in the material tray, batch acquisition can also produce a larger spacing between the materials carried by the transfer mechanism each time, and the transfer mechanism has less difficulty in obtaining the odd-numbered materials or the even-numbered materials, and the grabbing is safer and more reliable.

DETAILED DESCRIPTION

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "or / and" used herein includes any and all combinations of one or more related listed items.

[0039] The present invention provides a material taking auxiliary mechanism 100, which is used to selectively constrain or loosen the material in the material tray 200. When the material is in a constrained state, it is fixedly contained in the material tray 200; when the material is in a loosened state, it can be taken by the transfer mechanism 400 and leave the material tray 200, and the material enters the downward operation station after leaving.

[0040] The material picking auxiliary mechanism 100 can be used in conjunction with the conveying mechanism of the production line, and can be fixedly arranged relative to the conveying mechanism in the conveying direction of the conveying mechanism. When the material tray 200 passes the position corresponding to the material picking auxiliary mechanism 100, the material picking auxiliary mechanism 100 is adapted and connected with the tray 200. In the following period of time, the conveying mechanism stops conveying the tray 200 to wait for the material picking auxiliary mechanism 100 to loosen the material in the tray 200. After each loosening operation is completed, a part of the material is obtained by the transfer mechanism 400 and removed from the tray 200. Finally, after all the materials in the tray 200 are transferred, the conveying mechanism resumes operation to continue conveying the empty tray 200.

[0041] Embodiment 1

[0042] See also Figure 1-Figure 5 ,in Figure 3A tray 200 for carrying and accommodating an accessory 300 is shown. The accessory 300 may be an injection tube, or other types of medical consumables or accessories for constituting medical consumables. The tray 200 is provided with a plurality of equally spaced material partitions 2001, the material partitions 2001 having a certain elastic deformation capability, and a strip-shaped slot-shaped material placement position 2002 is formed between two adjacent material partitions 2001 for accommodating the accessory 300, and the inner wall surface of the slot of the material placement position 2002 is matched with the outer peripheral wall of the accessory 300. The tray 200 is formed by deep drawing of a whole piece of plastic sheet, and a plurality of deep-drawn cavities are formed correspondingly at the bottom of the tray 200, that is, the side of the tray 200 away from the slot opening of the material placement position 2002, and the deep-drawn cavities are extended along the convex direction of the material partition 2001, thereby making the material partition 2001 a thin-walled structure and obtaining elastic deformation capability.

[0043] The material picking auxiliary mechanism 100 includes a bearing assembly 30 and a material loosening member 10. The bearing assembly 30 is arranged opposite to the conveying mechanism in the production line when the material picking auxiliary mechanism 100 is installed and arranged, and the bearing assembly 30 also serves as the installation basis of the material loosening member 10. Specifically, the conveying mechanism has a supporting portion for supporting the material tray 200, and the bearing assembly 30 is located on the side of the conveying mechanism away from its supporting portion. The position of the supporting portion corresponding to the bearing assembly 30 is provided with a material loosening execution opening. When the material tray 200 passes the position of the supporting portion corresponding to the bearing assembly 30, its bottom is exposed through the material loosening execution opening.

[0044] The loose material pieces 10 are arranged in rows and spaced apart, and their arrangement direction is consistent with the conveying direction of the conveying mechanism. When the material tray 200 passes through the part of the conveying mechanism corresponding to the bearing assembly 30 (hereinafter referred to as the material taking section), the arrangement direction of the material partition 2001 and the material placement position 2002 of the material tray 200 is the same as the arrangement direction of the loose material pieces 10. The bearing assembly 30 is provided with a plurality of second adapter parts that are arranged in rows and spaced apart and correspond to the plurality of loose material pieces 10 one by one. The middle of both ends of each loose material piece 10 is rotatably mounted on the bearing assembly 30 through the second adapter part corresponding to this loose material piece 10. The ends of the plurality of loose material pieces 10 pointing to the material tray 200 all protrude relative to the bearing assembly 30 toward the side of the conveying mechanism. The end of the loose material piece 10 protruding relative to the bearing assembly 30 toward the side of the conveying mechanism is referred to as the loose material part of the loose material piece 10.

[0045] The material picking auxiliary mechanism 100 also includes a lifting assembly 60 for driving the lifting and lowering movement of the bearing assembly 30. When the material tray 200 reaches the material picking section of the conveying mechanism, the lifting assembly 60 outputs a driving force to the bearing assembly 30 to drive the bearing assembly 30 to move upward, so that the loosening member 10 follows the bearing assembly 30 to move synchronously upward to approach the material tray 200, and then the loosening member 10 passes through the loose material to perform the opening. When the lifting assembly 60 drives the bearing assembly 30 to move upward to the rising end, the material picking auxiliary mechanism 100 is adapted to be connected with the material tray 200, at which time each loosening member 10 is respectively connected to the material separation part 2001 of the material tray 200, specifically, the loosening part of each loosening member 10 is respectively extended into the deep drawing cavity of the corresponding material separation part 2001 of the loosening member 10, and then the corresponding material separation part 2001 can be driven to move by controlling the loosening member 10 to move, thereby changing the opening size of the corresponding material placement position 2002 to perform the loosening operation of the accessory 300. After all accessories 300 are moved out of the tray 200 by the transfer mechanism 400, the lifting assembly 60 drives the supporting assembly 30 to move downward, and the supporting assembly 30 drives the loosening part 10 away from the tray 200 to release the adaption connection between the material picking auxiliary mechanism 100 and the tray 200. When the loosening part completely leaves the drawing cavity of the tray 200, the conveying mechanism can resume operation to transport the empty tray 200 out of the material picking section.

[0046] There is a gap between any two adjacent loose material pieces 10, and the gap forms a loose material opening 20 of the loose material piece 10. When the material taking auxiliary mechanism 100 is adapted and connected with the material tray 200, the loose material piece 10 is connected with the material partition 2001 in a one-to-one correspondence, and the loose material opening 20 and the material placement position 2002 are also matched in a one-to-one correspondence. Since the ends of the loose material piece 10 pointing to the material tray 200 are both extended into the deep-drawn cavity of the material partition 2001, the loose material opening 20 on the side of the loose material piece 10 can change its opening synchronously with the material placement position 2002 on the side of the material partition 2001 matching this loose material piece 10. For example, when the material loosening piece 10 tilts to one side, the opening of the material loosening opening 20 on that side becomes smaller, and the opening of the material loosening opening 20 on the other side becomes larger, and the material partition 2001 matching the material loosening piece 10 and the material loosening piece 10 tilt in the same direction, so the opening of the material placement position 2002 of the material loosening opening 20 with a smaller opening becomes smaller, and the opening of the material placement position 2002 of the material loosening opening 20 with a larger opening becomes larger. Even if there are multiple material loosening pieces 10, the movement of the material loosening pieces 10 is carried out in an orderly manner, rather than in an irregular manner, so that the orderly movement of the material placement position 2002 of the material tray 200 and the orderly opening change control can be achieved.

[0047] In the first embodiment, the loose material pieces 10 are divided into two groups, namely, the main loose material pieces 101 and the auxiliary loose material pieces 102, which are arranged alternately one by one; the loose material openings 20 are divided into two groups, namely, the odd-position loose material openings 201 and the even-position loose material openings 202, which are arranged alternately one by one. The so-called odd position and even position refer to: counting from the starting end of the arrangement of the individual under discussion, the corresponding odd number sequence and the corresponding even number sequence, which will not be repeated below. Each non-end loose material piece 10, whether it is a main loose material piece 101 or an auxiliary loose material piece 102, has an odd-position loose material opening 201 and an even-position loose material opening 202 on both sides. The so-called non-end refers to: excluding the loose material piece 10 corresponding to the end of the material tray 200, that is, other loose material pieces 10 except the two individuals at the head end and the tail end among the multiple loose material pieces 10, these loose material pieces 10 can correspond one to one with other partitions 2001 in the material tray 200 except the head end partition 2001 and the tail end partition 2001. Each loose material opening 20, whether it is an odd-position loose material opening 201 or an even-position loose material opening 202, is formed between a main loose material piece 101 and an auxiliary loose material piece 102 adjacent thereto. For the convenience of description, after the material picking auxiliary mechanism 100 is adapted and connected with the material tray 200, the material partitioning part 2001 that matches the main material loosening part 101 is referred to as the first material partitioning part 2001, and the material partitioning part 2001 that matches the auxiliary material loosening part 102 becomes the second material partitioning part 2001; the material placement position 2002 that matches the odd-position material loosening port 201 is referred to as the odd-position material position 2002, and the material placement position 2002 that matches the even-position material loosening port 202 is referred to as the even-position material position 2002.

[0048] The material picking auxiliary mechanism 100 also includes an adjustment component 40, which includes a first adjustment unit 41 and a second adjustment unit 42 arranged on a side of the bearing component 30 relatively far from the conveying mechanism / material tray 200, and the first adjustment unit 41 and the second adjustment unit 42 extend side by side along the arrangement direction of the loose material pieces 10. The first adjustment unit 41 is provided with a plurality of first transfer parts distributed in rows and corresponding to the main loose material pieces 101 one by one, and one end of each main loose material piece 101 relatively far from the conveying mechanism / material tray 200 is rotatably connected to the first adjustment unit 41 through the first transfer part corresponding to the main loose material piece 101; the second adjustment unit 42 is provided with a plurality of first transfer parts distributed in rows and corresponding to the auxiliary loose material pieces 102 one by one, and one end of each auxiliary loose material piece 102 relatively far from the conveying mechanism / material tray 200 is rotatably connected to the second adjustment unit 42 through the first transfer part corresponding to the auxiliary loose material piece 102. For the convenience of description, one end of the main loosening member 101 connected to the first adjusting unit 41 and one end of the auxiliary loosening member 102 connected to the second adjusting unit 42 are referred to as the adjusting end of the loosening member 10 .

[0049] Thus, each loosening member 10 can act as an independent lever and rotate with the second transition part as the rotation center, wherein the part from the adjustment end to the second transition part is the power arm, and the part from the loosening part to the second transition part is the resistance arm. The loosening member 10 rotates around the second transition part to make its resistance arm tilt, and the spacer 2001 and the resistance arm of the loosening member 10 corresponding to the spacer 2001 tilt synchronously.

[0050] The first adjusting unit 41 can drive the main loose material piece 101 to tilt and swing synchronously by moving in the arrangement direction of the loose material piece 10, and the second adjusting unit 42 can also drive the auxiliary loose material piece 102 to tilt and swing synchronously by moving in the arrangement direction of the loose material piece 10. The first adjusting unit 41 and the second adjusting unit 42 can generate relative motion along the arrangement direction of the loose material piece 10, so the direction in which the first adjusting unit 41 drives the main loose material piece 101 to tilt and swing is opposite to the direction in which the second adjusting unit 42 drives the auxiliary loose material piece 102 to tilt and swing, thereby achieving the following effect: the opening change trend of the odd-position loose material opening 201 is opposite to the opening change trend of the even-position loose material opening 202, for example, when the opening of one of the odd-position loose material openings 201 becomes larger, the opening of the two even-position loose material openings 202 adjacent to the odd-position loose material opening 201 will inevitably become smaller. Therefore, the opening change trend of the odd-position material level 2002 is opposite to the opening change trend of the even-position material level 2002. When one of the odd-position material levels 2002 follows the odd-position release port 201 that matches the odd-position material level 2002 and synchronously expands its opening, the adjacent even-position material level 2002 follows the even-position release port 202 that matches the even-position material level 2002 and synchronously reduces its opening.

[0051] The material picking auxiliary mechanism 100 also includes a driving component 70, which is driven and connected to the first adjusting unit 41 or the second adjusting unit 42, and is capable of generating a first displacement to drive one of the first adjusting unit 41 and the second adjusting unit 42 to move relative to the other in a first direction along the arrangement direction of the loose material piece 10, or generating a second displacement to drive one of the first adjusting unit 41 and the second adjusting unit 42 to move relative to the other in a second direction along the arrangement direction of the loose material piece 10. Therefore, the driving component 70 generates the first displacement and the second displacement in sequence, thereby orderly driving each individual in the main loosening parts 101 to perform positive and reverse tilting activities relative to each individual in the auxiliary loosening parts 102, so that the odd-position loosening opening 201 and the even-position loosening opening 202 change their respective opening sizes at the same time with opposite opening change trends, and finally the opening of the odd-position material level 2002 and the opening of the even-position material level 2002 change at the same time with opposite change trends, thereby making the odd-position material level 2002 and the even-position material level 2002 expand their openings in sequence, thereby realizing orderly loosening of the accessories 300 in batches.

[0052] The adjustment component 40 also includes a swing transmission member 51 located outside the same end of the first adjustment unit 41 and the second adjustment unit 42, and the swing transmission member 51 includes a first hinged end rotatably connected to one end of the first adjustment unit 41 and a second hinged end rotatably connected to one end of the second adjustment unit 42, that is, the first adjustment unit 41 and the second adjustment unit 42 are rotatably connected to the first hinged end and the second hinged end at the same end. In this way, the linkage control of the first adjustment unit 41 and the second adjustment unit 42 can be achieved. If the driving component 70 drives the first adjustment unit 41 to slide forward along the arrangement direction of the loose material 10 through the first displacement, the swing transmission member 51 drives the second adjustment unit 42 to slide in the opposite direction along the arrangement direction of the loose material 10; if the driving component 70 drives the first adjustment unit 41 to slide in the opposite direction along the arrangement direction of the loose material 10 through the second displacement, the swing transmission member 51 drives the second adjustment unit 42 to slide forward along the arrangement direction of the loose material 10. Therefore, the activity control of the two adjustment units can be completed by driving only one drive assembly 70, and there is no need to respectively provide two drive assemblies 70 for the two adjustment units.

[0053] The driving assembly 70 includes a linear driving source and a sliding transmission member 52 that slidably cooperates with the linear driving source. The sliding transmission member 52 is fixedly connected to one of the first adjustment unit 41 and the second adjustment unit 42. The sliding cooperation formed between the sliding transmission member 52 and the linear driving source enables the sliding transmission member 52 to have the freedom of movement to slide along the arrangement direction of the loose material parts 10. The swing transmission member 51 is fixedly installed on the side of the bearing assembly 30 away from the conveying mechanism / material tray 200, and will not move following the power output of the linear driving source.

[0054] In order to adapt to the material loosening of the first embodiment, the transfer mechanism 400 includes a plurality of material taking parts 401 arranged in rows and spaced apart, wherein the distance between any two adjacent material taking parts 401 is twice the width of the material position 2002 of the material tray 200. In other words, the two adjacent material taking parts 401 do not take two adjacent materials placed on the material tray 200, but take materials with one material in between. Therefore, the material taking parts 401 only take the odd-position materials or only take the even-position materials each time, instead of taking the odd-position materials and the even-position materials at the same time.

[0055] It is worth noting that the present invention does not specifically limit the specific type of material. In addition to the accessory 300, other types of materials can also be constrained and loosened. In addition, the material tray 200 does not need to be formed by deep drawing of a whole plastic plate. In other words, the material picking auxiliary mechanism 100 can also form an adaptive connection with other types of material trays 200; the material picking auxiliary mechanism 100 does not have to be set on the side of the conveying mechanism away from its supporting part, but can also be set opposite to the supporting part of the conveying mechanism. At this time, the loosening member 10 can directly move relatively close to the material tray 200 from the side outside the opening of the slot of the material placement position 2002 to connect to the material partition 2001 corresponding to this loosening member 10.

[0056] It should also be noted that, in other embodiments, the number of loosening pieces 10 may be less than or more than the number of material partitions 2001 of the material tray 200, and may not be exactly equal to the number of material partitions 2001. In the case where the number of loosening pieces 10 is less than the number of material partitions 2001, the conveying mechanism may first drive a portion of the material tray 200 to the material fetching section, while the other portion is still located outside the material fetching section, and the number of material partitions 2001 of the material tray 200 located in the material fetching section is equal to the number of loosening pieces 10. After this portion of the material is moved out of the material tray 200, the conveying mechanism drives the portion of the material tray 200 that has not reached the material fetching section to reach the material fetching section, and enables the material fetching auxiliary mechanism 100 to continue to perform material restraint and loosening operations on the portion of the material tray 200 that has recently arrived.

[0057] When the number of loose material pieces 10 is greater than the number of material partitioning parts 2001, the material picking auxiliary mechanism 100 can also control the movement of a part of the loose material pieces 10 to change the opening of the loose material openings 20 of this part of the loose material pieces 10, and the number of this part of the loose material pieces 10 that can perform tilting movement is exactly equal to the number of material partitioning parts 2001 of the material tray 200, and the number of this part of the loose material openings 20 that can change the opening is exactly equal to the number of material placing positions 2002 of the material tray 200.

[0058] In some embodiments, not all of the loosening pieces 10 are rotatably mounted on the bearing assembly 30, and some of the loosening pieces 10 may be fixedly mounted on the bearing assembly 30. For example, the loosening pieces 10 may also include first loosening pieces 10 and second loosening pieces 10 that are alternately arranged one by one, the first loosening pieces 10 are rotatably mounted on the bearing assembly 30, and the second loosening pieces 10 are fixedly mounted on the bearing assembly 30, and each loosening opening 20 is formed between a first loosening piece 10 and a second loosening piece 10 adjacent thereto. The adjustment assembly 40 is movably connected to the adjustment end of the first loosening piece 10, and the driving assembly 70 drives the adjustment assembly 40 to sequentially perform positive linear displacement and reverse directional displacement along the arrangement direction of the loosening pieces 10, thereby driving the first loosening piece 10 to sequentially tilt positively and reversely relative to the second loosening piece 10, thereby enabling the odd-position loosening opening 201 and the even-position loosening opening 202 to expand their openings sequentially.

[0059] Embodiment 2

[0060] In the second embodiment, the loose material pieces 10 are also arranged in rows, but are not divided into groups. On both sides of each loose material piece 10 are a pair of odd-position loose material openings 201 and even-position loose material openings 202 adjacent to each other, and between any two adjacent loose material pieces 10, there is an odd-position loose material opening 201 and an even-position loose material opening 202 adjacent to the odd-position loose material opening 201. The middle of both ends of each loose material piece 10 is also rotatably mounted on the bearing assembly 30. The adjustment end points to the outer side of the bearing assembly 30 relatively away from the conveying mechanism / material tray 200, and the loose material portion points to the conveying mechanism / material tray 200.

[0061] In the second embodiment, the loosening piece 10 matches the material partition part 2001 in a manner of spacing one material partition part 2001, and the loosening piece 10 is matched to the first material partition part 2001, or the loosening piece 10 is matched to the second material partition part 2001. The adjustment ends of these loosening pieces 10 are connected to the same adjustment unit, and the driving component 70 drives the adjustment unit to move forward along the arrangement direction of the loosening piece 10 by generating a first displacement, or drives the adjustment unit to move backward along the arrangement direction of the loosening piece 10 by generating a second displacement. Therefore, each loosening piece 10 can change the opening of the odd-position loosening opening 201 and the even-position loosening opening 202 on both sides of it inversely through the tilting movement. When the material picking auxiliary mechanism 100 is adapted and connected to the material tray 200, the resistance arms of the multiple material loosening parts 10 can all move sideways in the same orientation to drive the first material partition part 2001 or the second material partition part 2001 to move sideways in the same orientation, so that the odd-position material level 2002 and the even-position material level 2002 on both sides of the material partition part 2001 change their respective openings in reverse.

[0062] Embodiment 3

[0063] In the third embodiment, the loose material pieces 10 are also arranged in rows without group division. On both sides of each loose material piece 10 are a pair of adjacent odd-position loose material openings 201 and even-position loose material openings 202, and an odd-position loose material opening 201 or an even-position loose material opening 202 is formed between any two adjacent loose material pieces 10. The middle of both ends of each loose material piece 10 is also rotatably mounted on the bearing assembly 30. The loose material pieces 10 are matched with the partitions 2001 in a one-to-one continuous corresponding manner, and the adjustment ends of these loose material pieces 10 are all connected to the same adjustment unit. The driving assembly 70 drives the adjustment unit to move forward along the arrangement direction of the loose material pieces 10 by generating a first displacement to drive these loose material pieces 10 to tilt forward synchronously, or drives the adjustment unit to move reversely along the arrangement direction of the loose material pieces 10 by generating a second displacement to drive the adjustment unit to tilt reversely synchronously. When the material taking auxiliary mechanism 100 is adapted and connected with the material tray 200 , the material release opening 20 matches the material placement position 2002 in a one-to-one continuous correspondence manner.
