[0041] Example 1

[0042] Please see Figure 1 Each workpiece 31 is provided with an open receiving cavity, and multiple workpieces 31 are stacked sequentially through the opening of the receiving cavity to form material 30 to be separated. In the embodiments of this application, the material 30 is defined as having a first end and a second end, specifically the end of the material 30 that exposes the aforementioned opening is designated as the first end, and the other end away from the opening is designated as the second end.

[0043] For ease of description and understanding, the first workpiece 31 located at the second end is set as the workpiece 31 to be divided, and the second workpiece 31 adjacent to it is set as the next workpiece 31. When the first workpiece 31 is successfully divided, the original next workpiece 31 is transformed into the first workpiece 31.

[0044] It is understood that, based on the features and structure of products circulating in the market, the workpiece 31 separated in this application embodiment usually has a protrusion formed on the edge of the opening end. The extension direction of the protrusion can be perpendicular to the opening direction of the first end; or the protrusion can be set as multiple discontinuous ones, or as a continuous annular closed structure.

[0045] For ease of description and understanding, this embodiment uses the aforementioned material box with an irregular disc-like structure as workpiece 31. Specifically, the material box is a roughly disc-shaped plastic shell, and the open end of the material box is provided with an annular protrusion. During material distribution, the annular protrusion serves as the force point for material distribution; in actual use, the cover is provided with a groove that matches the annular protrusion. Through the engagement of the groove and the annular protrusion, the material box and the cover are closed to each other, thereby assembling a complete box.

[0046] As can be seen from the background technology, during the specific material dispensing process, due to the thinness and low hardness of the material box, it is prone to deformation and twisting under stress, resulting in unsuccessful dispensing or the shape of the material box not conforming to production standards after successful dispensing. For ease of understanding, this embodiment will be described using a medical material dispensing tray, but this is not intended to limit the application field of the material tray in this application.

[0047] Please see Figure 1 and Figure 3 In order to solve the above-mentioned technical problems, this application provides a material distribution device, which includes a feeding mechanism 100 and a material picking mechanism 200.

[0048] First, please refer to further information. Figure 1 The feeding mechanism 100 includes a storage slide 110, a feeding structure 120 and multiple limiting structures 130. In this embodiment, the feeding mechanism 100 is used to process the material 30.

[0049] The storage chute 110 is not limited in shape. For example, the storage chute 110 can be set as a closed chute or an open chute. This embodiment is illustrated by an example of an open chute.

[0050] Specifically, the storage chute 110 is formed by multiple first guide rods 111. When the material 30 is placed into the storage chute 110, the multiple first guide rods 111 are evenly distributed around the material 30. Therefore, each interval is connected to the outside, and the storage chute 110 is in an open state.

[0051] In some other embodiments, the storage chute 110 further includes a first mounting plate 112 and a second mounting plate 113. The aforementioned plurality of first guide rods 111 are disposed on the side of the first mounting plate 112 away from the second mounting plate 113, and a plurality of second guide rods 114 are disposed between the first mounting plate 112 and the second mounting plate 113.

[0052] For ease of description and understanding, this embodiment defines the space defined by multiple first guide rods 111 as the first storage chute 101, and the space defined by multiple second guide rods 114 as the second storage chute 102. The first storage chute 101 and the second storage chute 102 together form the aforementioned storage chute 110. Based on this, the first mounting plate 112 and the second mounting plate 113 provide a foundation for mounting and supporting the first guide rods 111 and the second guide rods 114. The first mounting plate 112 and the second mounting plate 113 are provided with connecting holes corresponding to the first storage chute 101 and the second storage chute 102, allowing material 30 to pass through.

[0053] Therefore, material 30 moves from the first storage chute 101 to the second storage chute 102. The specific moving principle is further explained in this embodiment as follows:

[0054] First, in order to improve the automation level of the embodiments of this application and ensure the material distribution efficiency of the material 30, the first storage slide 101 is set to an inclined downward posture, that is, the material 30 is put into the upper end of the first storage slide 101 and automatically slides down to the lower end of the first storage slide 101 under the action of gravity.

[0055] Secondly, the feeding structure 120 also has multiple feeding groups 121 arranged near the discharge end of the storage chute 110. Specifically, the feeding group 121 is located on the second storage chute 102. When the material 30 enters the second storage chute 102 from the first storage chute 101, the feeding group 121 directly contacts each workpiece 31 and controls whether each workpiece 31 needs to move, or whether multiple workpieces 31 need to move continuously, thereby controlling the specific progress of the feeding action. Therefore, the feeding group 121 has the function of controlling the feeding speed and the feeding process.

[0056] Multiple limiting structures 130 are pre-installed at the ends of the storage slide 110, forming a discharge port adapted to the shell shape of the medical material box. That is, the limiting structures 130 are located on the side of the second mounting plate 113 away from the first mounting plate 112. In this embodiment, when the material 30 is placed into the storage slide 110, the limiting structures 130 can also act on the annular protrusion of the medical material box to ensure the stability of the medical material box when it is not dispensed.

[0057] Specifically, multiple limiting structures 130 can cooperate to open and close the discharge port. Each limiting structure 130 can rotate to open the discharge port under external force and reset to stop the discharge port when the external force disappears. When the discharge port is open, the annular protrusion disengages from the limiting structure 130, and the medical material box is released from the storage slide 110 to achieve material distribution. When the discharge port resets, the annular protrusion of the next medical material box forms an abutment relationship with the limiting structure 130. Therefore, with each opening and closing of the limiting structure 130, the embodiment of this application realizes the material distribution of one medical material box.

[0058] Since the limiting structure 130 is preset at the discharge end of the storage slide 110, and the first guide rod 111 that defines the storage slide 110 is evenly distributed around the material 30, the design scheme of the limiting structure 130 and the first guide rod 111 can stably maintain the placement state of the material 30 and improve the reliability of the material distribution device.

[0059] Each limiting structure 130 includes a first limiting part 131 and a second limiting part 132. The second limiting part 132 is rotatably and reset to be connected to the first limiting part 131. The multiple first limiting parts 131 are distributed according to the shape of the medical cassette. In this embodiment, the first limiting part 131 is designed as a rod-shaped structure. The rotational reset connection between the second limiting part 132 and the first limiting part 131 is achieved by an elastic member 133.

[0060] Specifically, the first limiting part 131 and the second guide rod 114 are designed to be staggered, that is, the projections of the first limiting part 131 and the second guide rod 114 do not overlap on the projection surface of the second mounting plate 113. The staggered design has at least the following two advantages:

[0061] Firstly, during manufacturing, the second guide rod 114 and the first limiting part 131 are fixedly connected to the second mounting plate 113. Whether by welding or plugging, the staggered arrangement of the second guide rod 114 and the first limiting part 131 can effectively avoid stress concentration and ensure the stability of the second guide rod 114 and the first limiting part 131.

[0062] Secondly, during use, the material 30 is continuously stacked in the second guide rod 114 and the first limiting part 131. The second guide rod 114 and the first limiting part 131 are staggered, which helps to support the material 30 from all directions, maintain the placement posture of the material 30, and facilitate subsequent material distribution.

[0063] The material feeding structure 120 has at least a plurality of material distribution groups 122 arranged around the discharge port, and the material feeding structure 120 also has a plurality of feeding groups 121 arranged near the discharge port in the material storage chute 110. The design of the feeding group 121 and the material distribution group 122 in cooperation is a preferred embodiment of this application. It is understood that if the material feeding structure 120 does not have feeding groups 121, it can still meet the purpose of distributing materials one by one, but the distributing effect is not good.

[0064] Specifically, the material distribution group 122 is located between adjacent first limiting parts 131, while the feeding group 121 is located between adjacent second guide rods 114. Therefore, in this embodiment, the material distribution group 122 and the feeding group 121 are spaced apart along the extension direction of the storage slide 110, and a material distribution gap is reserved between the material distribution group 122 and the feeding group 121. The materials 30 within the material distribution gap are still in a stacked state and are distributed one by one by the material distribution group 122.

[0065] Please refer to further information. Figure 2 In some embodiments of this application, the feeding group 121 consists of two oppositely arranged first ratchet wheels 1211, and the dispensing group 122 consists of two oppositely arranged second ratchet wheels 1221. The first ratchet wheels 1211 and the second ratchet wheels 1221 are moved toward the discharge port, so that the material 30 is transferred toward the discharge port and dispensed. In the embodiments of this application, the first ratchet wheels 1211 and the second ratchet wheels 1221 are set to dispense the amount of material 30 each time as one medical material box.

[0066] It is understood that, based on actual production needs, the tooth pitch of the first ratchet 1211 and the second ratchet 1221 can be adjusted in this embodiment to meet different production requirements. For example, it may be necessary to move two, three, or more pieces of material 30 each time. Of course, the number of pieces of material 30 moved by the first ratchet 1211 and the second ratchet 1221 each time can be the same or different, and this is not limited here.

[0067] The first ratchet 1211 and the second ratchet 1221 rotate under the action of the drive mechanism 123, thereby realizing the movement of the material 30. The drive mechanism 123 can be a motor or a cylinder, etc. When the first ratchet 1211 and the second ratchet 1221 move the same amount of material 30 each time, all the first ratchet 1211 and the second ratchet 1221 can be driven by the same drive mechanism 123, or they can be driven by multiple corresponding drive mechanisms 123. When the first ratchet 1211 and the second ratchet 1221 move different amounts of material 30 each time, the first ratchet 1211 and the second ratchet 1221 are driven by multiple corresponding drive mechanisms 123.

[0068] Regarding the first ratchet 1211, by controlling the rotation speed of the first ratchet 1211, the flow rate of the medical material box can be controlled, preventing too many medical material boxes between the feeding group 121 and the dispensing group 122. On the one hand, this reduces the pressure of other medical material boxes on the first medical material box, and on the other hand, it provides space for the first medical material box to dispense materials.

[0069] Regarding a single second ratchet 1221, the second ratchet 1221 has two sides when peeling off the medical material box, which are defined as the discharge side 1222 and the peeling side 1223 respectively. The first medical material box is located on the discharge side 1222, and the second medical material box is located on the peeling side 1223.

[0070] To improve material dispensing efficiency and quality, the feeding mechanism 100 in this embodiment further includes an air blowing structure 140. The air blowing end of the air blowing structure 140 faces the peeling side 1223 of the medical material box in contact with the dispensing group 122. The air blowing structure 140 includes universal nozzles 141. The number of universal nozzles 141 is the same as the number of second ratchet 1221 and corresponds one-to-one. The air blowing end of the universal nozzles 141 blows plasma air towards the peeling side 1223. The position near the universal nozzles 141 is high-pressure gas. The high-pressure gas diffuses to the low-pressure position, forcing a gap of 2 to 5 mm to be formed between the first medical material box and the second medical material box, so as to achieve the effect of plasma air eliminating electrostatic adsorption between the medical material boxes.

[0071] Understandably, the plasma wind possesses a certain kinetic energy. To prevent the medical material container from being ejected by force, the limiting structure 130 should be configured to resist the blowing action of the plasma wind. Furthermore, since the first ratchet 1211 controls the flow rate of the medical material container, there are relatively few medical material containers between the feeding group 121 and the dispensing group 122. Consequently, under the action of the high-pressure gas from the universal nozzle 141, the second medical material container can move away from the first medical material container, facilitating the separation of the first and second medical material containers to form a gap.

[0072] Secondly, please refer to the following: Figure 2 and Figure 3 The material handling mechanism 200 is used to transfer the position of the medical material box. In this embodiment, the material 30 is mainly processed by the material feeding mechanism.

[0073] Based on the above embodiments, the material handling mechanism 200 used in this application includes a movable material handling structure 210, which moves closer to and further away from the discharge port during its travel. The material handling structure 210 and / or the material distribution group 122 can move the medical material box along the discharge direction and drive the limiting structure 130 to open the discharge port. Therefore, the force applied by the material handling structure 210 and / or the material distribution group 122 is the aforementioned external force. When the material handling structure 210 and / or the material distribution group 122 stops applying the force, the external force disappears.

[0074] Furthermore, the following three explanations are given regarding the application of force:

[0075] The first method involves the material distribution group 122 pushing the medical material box and forcing the limiting structure 130 to rotate and open the discharge port, while the part removal structure 210 simply removes the medical material box.

[0076] The second method is that the material distribution group 122 pushes the medical material box to move, but it is not enough to make the limiting structure 130 rotate and open the outlet. Therefore, the picking structure 210 needs to pick up the medical material box and cooperate with the material distribution group 122 to force the limiting structure 130 to rotate and open the outlet.

[0077] The third type is where the material distribution group 122 only drives the medical material box to move, but does not cause the limiting structure 130 to rotate. It relies entirely on the removal structure 210 to remove the medical material box and force the limiting structure 130 to open the discharge port.

[0078] The picking structure 210 includes an adsorption seat 211 and an adsorption element 212 disposed on the adsorption seat 211. The adsorption seat 211 is detachably disposed on the moving end and can move so that the adsorption element 212 approaches and moves away from the discharge port. When the adsorption element 212 approaches the discharge port, the adsorption element 212 picks up the first medical material box. When it moves away from the discharge port, the adsorption element 212 carries the first medical material box and transfers it.

[0079] Furthermore, the material handling mechanism 200 also includes a material handling drive 213, a mounting base 214, and a swing arm assembly 215. The mounting base 214 is located near the discharge port. The mounting end of the swing arm assembly 215 is located on the mounting base 214 and is connected to the material handling drive 213. The material handling structure 210 is located at the moving end of the swing arm assembly 215. The moving end of the swing arm assembly 215 is close to and away from the discharge port at both ends of its travel stroke. Specifically, the moving end of the swing arm assembly 215 is connected to the adsorption seat 211.

[0080] The material handling drive component 213 is a motor. When the motor rotates forward, it drives the swing arm assembly 215 to move toward the discharge port. When the motor rotates in reverse, it drives the swing arm assembly 215 to move away from the discharge port.

[0081] Please refer to the following: Figure 3 and Figure 4 A guide groove 2141 is provided on the side wall of the mounting base 214, and the swing arm assembly 215 is slidably connected to the guide groove 2141; the guide groove 2141 is adapted to the moving path of the moving end, and in this embodiment, the guide groove 2141 can be set to be arc-shaped.

[0082] The swing arm assembly 215 includes a crank 2151, a rocker arm 2152, a connecting rod 2153, and a rotating sleeve 2154. The crank 2151 is connected to the material picking drive 213. The rocker arm 2152 is rotatably connected to the crank 2151 and the connecting rod 2153 respectively. The rotation shafts of the rocker arm 2152 and the connecting rod 2153 slide in the guide groove 2141. The connecting rod 2153 is rotatably connected to the adsorption seat 211. The adsorption seat 211 is provided with an insertion rod 2111. The insertion rod 2111 is movably inserted into the rotating sleeve 2154. The rotating sleeve 2154 is rotatably connected to the mounting base 214.

[0083] Please see Figures 5 to 7 The material-taking drive 213 rotates forward to drive the crank 2151 to move, thereby driving the rocker arm 2152, connecting rod 2153 and adsorption seat 211 to move. The insertion rod 2111 slides along the rotating sleeve 2154 under the restriction of the rotating sleeve 2154. The rotating sleeve 2154 rotates adaptively relative to the mounting seat 214, so that the adsorption element 212 rotates upward while approaching the discharge port, and the adsorption element 212 performs adsorption.

[0084] Similarly, the material picking drive 213 reverses, causing the adsorption member 212 to rotate downwards while moving away from the discharge port, and the adsorption member 212 releases adsorption. Therefore, the embodiments of this application can not only realize the translation of the medical material box, but also the angle conversion, and have three-dimensional position movement.

[0085] Compared to the design using three-dimensional motion modules in related technologies, the structure of this embodiment is simpler and has a cost advantage.

[0086] Please see Figure 8 The material distribution device also includes a sorting mechanism 300, which is set at the output end of the material handling mechanism 200. Specifically, the sorting mechanism 300 includes a detection element and a pusher 310. The detection element and the pusher 310 cooperate to act on the conveying path of the medical material box. When the detection value of the medical material box by the detection element is not equal to the preset value, it can be determined that the material distribution of the medical material box is unqualified, and the pusher 310 pushes and removes the unqualified medical material box.

[0087] The detection component is a sensor that determines whether the material is qualified by emitting and receiving the magnitude of reflected light. If a single-layer medical material box is used as the qualified standard, when detecting a double-layer medical material box, the light will be reflected from the second layer of the medical material box after passing through the first layer and then sent to the sensor. The sensor will then receive the reflected light from both layers of medical material boxes. Compared with a single-layer medical material box, the reflected light from a double-layer medical material box is greater than that from a single-layer medical material box, thus enabling the detection of double-layer or even multi-layer medical material boxes (i.e., unqualified medical material boxes). The unqualified medical material box is then pushed to another position by the pusher 310 for further processing.

[0088] Similarly, if a certain number of layers of medical material boxes is used as the standard for acceptance, the preset value of the test piece needs to be changed to change the judgment of non-conforming products and push the non-conforming products to other positions. Other positions can be set as a platform or a material bin 320 as storage positions.

[0089] The pusher 310 includes a cylinder and a pusher plate. The pusher plate is fixedly connected to the piston rod of the cylinder. During normal operation, the piston rod of the cylinder is in an extended state, and the pusher plate is located opposite the hopper 320. The material handling mechanism 200 moves the medical material box from the feeding mechanism 100 to between the pusher plate and the hopper 320. When a defective product is detected, the piston rod retracts, and the pusher plate pushes the defective product into the hopper 320 for storage.

[0090] Please refer to the following: Figure 2 , Figure 7 and Figure 8 In conjunction with the specific content of the above embodiments, the operating principle of the material distribution device will be further explained below:

[0091] S100. After the material 30 slides into the first storage chute 101, it continues to slide towards the second storage chute 102 under its own gravity.

[0092] S200. After material 30 enters the second storage chute 102, it is conveyed to the first limiting part 131 at a preset flow rate under the action of two first ratchet wheels 1211.

[0093] S300. With the cooperation of two second ratchet wheels 1221 and universal nozzle 141, the material 30 is distributed into single-layer medical material boxes one by one;

[0094] S400. The material picking drive 213 rotates forward and drives the swing arm assembly 215 to swing, thereby causing the adsorption component 212 to move to the discharge port and adsorb the medical material box. Then the adsorption component 212 transfers the medical material box to the preset position and releases it.

[0095] S500. The material picking drive 213 reverses and drives the swing arm assembly 215 to swing in the opposite direction, so that the adsorption component 212 moves back to the outlet for the next adsorption after releasing the medical material box.

[0096] S600. The sorting mechanism 300 removes non-conforming products.

[0097] Please refer to further information. Figure 8 This application embodiment also provides a subcontracting production line, which includes a conveying device 20 and the above-mentioned material distribution device. The conveying device 20 is provided with a plurality of discharge positions, which are close to the discharge end of the material distribution device.

[0098] In practical applications, the conveying device 20 includes a conveyor belt and / or drive rollers. The feeding mechanism 100 is located at one end of the conveying device 20, and the picking mechanism 200 is located on one side of the conveying device 20. The picking mechanism 200 picks up the material from the feeding mechanism 100 and places it on the conveying device 20, and then the conveying device 20 conveys it.

[0099] The sorting mechanism 300 and the picking mechanism 200 are arranged at intervals along the conveying direction of the conveying device 20. Specifically, the sorting mechanism 300 is far away from the feeding mechanism 100 relative to the picking mechanism 200, and the conveyor belt is located between the push plate and the hopper 320. When the medical boxes are conveyed in the conveying device 20, the sorting mechanism 300 checks whether the medical boxes are qualified, thereby rejecting unqualified products and keeping qualified products on the conveyor belt for continued conveying.

[0100] The subcontracting production line provided in this application embodiment has the functions of automatic material sorting, unloading, and feeding, with a high level of automation and saving labor costs.
