[0024] In order to improve feeding efficiency by enabling multi-product feeding, this application relates to a multi-product feeding device that can effectively utilize space while satisfying the feeding of multiple products.

[0025] In some embodiments of this application, see Figures 1 to 6 It describes the structure of a multi-product feeding device.

[0026] See Figure 1 The multi-product loading device includes a vibratory feeder assembly 100, a buffer clamp assembly 200, a PPU handling assembly 300, and a loading and handling assembly 400, all of which are fixed to, for example, a fixed platform 500.

[0027] See also Figure 1The vibratory feeder assembly 100 includes a vibratory feeder 110 and a vibratory feeder along the X-direction ( Figure 1 The straight vibrating track 120 (in the direction indicated by the solid arrow in the middle) is a standard vibrating plate assembly 100 in the industry. Vibrating plates 110 of different specifications can be customized according to different product forms.

[0028] For example, the vibratory plate 110 can be a cylindrical container, the straight vibration track 120 is a linear track, one end of the straight vibration track 120 has two inner surfaces that match the top plane and outer circumferential surface of the vibratory plate 110 respectively, and the straight vibration track 120 is located on one side of the vibratory plate 110 and is tangent to the outer circumferential surface of the cylinder. The connection method can be welding or screw connection.

[0029] During the feeding process, a batch of products to be fed is manually poured into the vibratory plate 110. The vibratory plate 110 adjusts the products to the required posture and discharges them to the feeding station along the X-axis straight vibration track 120.

[0030] The PPU (Parallel Positioning Unit) handling assembly 300 is also an industry-standard component that can be customized according to handling distance, load, and efficiency.

[0031] In some embodiments of this application, the PPU handling assembly 300 has a robotic arm (not labeled) capable of moving products from the loading station of the linear vibrating track 120 to the buffer station 231 in the buffer fixture assembly 200 (see [link]). Figure 2 and Figure 3 )superior.

[0032] The robotic arm can acquire products from the loading station in ways that are not limited to adsorption or gripping.

[0033] In some embodiments of this application, see Figure 2 and Figure 3 The cache fixture assembly 200 includes a first rack 210 and a fixture module ( Figure 3 (shown) and a first X-axis motion platform 220, wherein the buffer clamp assembly 200 is arranged on one side of the linear vibration track 120, wherein the clamp module is disposed on the first X-axis motion platform 220 and is used to move along the X-axis when the first X-axis motion platform 220 is in motion.

[0034] In some embodiments of this application, the PPU handling assembly 300 has a mounting frame (not labeled) with two mounting legs 310 fixed to a fixed platform 500. The buffer clamp assembly 200 passes through the two mounting legs 310 in the X direction, which facilitates the compact arrangement of the buffer clamp assembly 200 and the PPU handling assembly 300, and makes it easy for the PPU handling assembly 300 to handle products onto the buffer clamp assembly 200.

[0035] See Figure 2 The first X-axis motion platform 220 includes a first drive assembly, a first ball screw 223, an X-axis slide rail 222, and a first connecting block 225.

[0036] The first frame 210 is fixed to the fixed platform 500, which serves as the base of the first X-axis motion platform 220.

[0037] Both the first drive assembly and the first ball screw 223 can be fixed to the first frame 210. The screw extension direction of the first ball screw 223 is along the X direction. The first drive assembly is used to drive the first ball screw 223 to rotate (for example, the first drive assembly may include a drive motor 221).

[0038] The X-axis slide rail 222 can be fixed to the first ball screw 223, and the first connecting block 225 is fixedly connected to the threaded block 224 on the first ball screw 223 and slidably disposed on the X-axis slide rail 222. The first connecting block 225 is also connected to the clamping module. Therefore, when the drive motor 221 works, it drives the first ball screw 223 to rotate, and the threaded block 224 on it moves together with the first connecting block 225 and the clamping module in the X direction. Thus, the clamping module moves along the X direction.

[0039] In some embodiments of this application, see also Figure 2 and Figure 3 The fixture module includes a fixture platform 230 and a positioning platform 240. The fixture platform 230 is fixedly connected to the first X-axis motion platform 220. Specifically, the fixture platform 230 is fixedly connected to the first connecting block 225.

[0040] The fixture platform 230 has multiple buffer stations spaced apart along the X direction. Figure 2 and Figure 3 The diagram shows a buffer station 231, each buffer station 231 can hold a product that is transported from the loading station of the linear vibrating track 120 by the PPU handling assembly 300.

[0041] Although the products output from the linear vibrating track 120 have already been positioned once, in order to ensure the positioning reliability of the products transported to the buffer station 231 by the PPU handling component 300, so that the loading and handling component 400 can accurately transport the products on the buffer station 231, the positioning platform 240 needs to reposition the products at the buffer station 231.

[0042] In some embodiments of this application, the positioning platform 240 is slidably arranged on the fixture platform 230. After the PPU handling assembly 300 moves the product to the buffer station 231, the product is repositioned by the positioning platform 240.

[0043] See Figure 2 and Figure 3 The positioning platform 240 includes a positioning cylinder 241, a positioning seat 242 and a plurality of positioning components 243. The positioning cylinder 241 is fixedly arranged on the fixture platform 230. The positioning seat 242 is connected to the cylinder rod 2411 of the positioning cylinder 241 and is slidably arranged on the fixture platform 230.

[0044] Multiple positioning components 243 are fixed to the positioning base 242, and the number of positioning components 243 is the same as the number of cache stations 231, that is, one positioning component 243 corresponds to one cache station 231 (see Figure 3 ).

[0045] In some embodiments of this application, the extension and retraction direction of the cylinder rod 2411 is along the Y direction, which is perpendicular to the X direction in which the plurality of buffer stations 231 are arranged.

[0046] When the cylinder rod 2411 extends along the Y direction, the positioning seat 242, together with multiple positioning elements 243, slides in the direction in which the cylinder rod 2411 extends, so that the positioning elements 243 move away from the buffer station 231. At this time, the PPU handling assembly 300 can place the product to be handled on the buffer station 231. After placement, the cylinder rod 2411 retracts, and the positioning seat 242, together with multiple positioning elements 243, slides in the direction in which the cylinder rod 2411 retracts, so that the positioning elements 243 move closer to the buffer station 231. The free end of the positioning element 243, which is directly opposite the product placed at the buffer station 231, abuts against the product. Through the abutting force applied to the product by the positioning element 243, the product's posture is adjusted and maintained, ensuring the secondary positioning effect of the product.

[0047] In some embodiments of this application, see Figure 3 In order to achieve a stable connection between the cylinder rod 2411 and the positioning seat 242, the positioning platform 240 also includes a connector 270, which stably connects the cylinder rod 2411 and the positioning seat 242, ensuring that when the cylinder rod 2411 extends, it can push out the positioning seat 242, and when the cylinder rod 2411 retracts, it can bring the positioning seat 242 back.

[0048] The connector 270 is disposed on the cylinder rod 2411 and includes a first limiting part 271, a connecting part 272, and a second limiting part 273.

[0049] One end of the connecting part 272 is perpendicularly connected to the first limiting part 271 and the other end is perpendicularly connected to the second limiting part 273. The cross-sectional area of ​​the first limiting part 271 and the cross-sectional area of ​​the second limiting part 273 are both larger than the cross-sectional area of ​​the connecting part 272, so that the connecting part 270 is I-shaped.

[0050] See Figure 3 One end of the connecting part 272 is perpendicularly connected to the center position of the first limiting part 271, and the other end is perpendicularly connected to the center position of the second limiting part 273, so as to avoid unbalanced force on the positioning seat 242 when the cylinder rod 2411 extends or retracts.

[0051] Correspondingly, a limiting groove that mates with the connector 270 is arranged on the positioning seat 242, see [reference]. Figure 3 The limiting groove includes a first limiting groove 244 and a second limiting groove 245 that pass through in the Y direction. The length of the first limiting groove 244 in the X direction is less than the length of the second limiting groove 245 in the X direction, so that the limiting groove forms a convex-shaped limiting groove.

[0052] See Figure 3 The second limiting part 273 is located in the second limiting groove 245. The first limiting groove 244 extends along one edge in the X direction into the first U-shaped space located on one side of the connecting part 272, which is surrounded by the first limiting part 271, the connecting part 272 and the second limiting part 273, and abuts against the side of the first limiting part 271 and the second limiting part 273 in the first U-shaped space. The first limiting groove 244 extends along the other edge in the X direction into the second U-shaped space located on the other side of the connecting part 272, which is surrounded by the first limiting part 271, the connecting part 272 and the second limiting part 273, and abuts against the side of the first limiting part 271 and the second limiting part 273 in the second U-shaped space.

[0053] In this way, one side edge of the first limiting groove 244 is limited between the first limiting part 271 and the second limiting part 273 on the side of the connecting part 272, and the other side edge of the first limiting groove 244 is limited between the first limiting part 271 and the second limiting part 273 on the other side of the connecting part 272.

[0054] Therefore, when the cylinder rod 2411 extends and retracts along the Y direction, the connector 270 cannot disengage from the second limiting groove 245 in the Y direction. Furthermore, since the two sides of the first limiting groove 244 along the X direction abut against the first limiting part 271 and the second limiting part 273, the positioning seat 242 is ensured to slide stably along the Y direction when the cylinder rod 2411 extends and retracts along the Y direction.

[0055] In some embodiments of this application, see reference 1. Figure 2 To facilitate the stable sliding of the positioning platform 240, a first slide rail 250 and a second slide rail (not shown) are provided relatively parallel to each other on the fixture platform 230.

[0056] The first slide rail 250 and the second slide rail are located on both sides of the positioning cylinder 241, and the length of the slide rail is along the Y direction.

[0057] The positioning seat 242 and the first slider 260 are fixedly connected, and the first slider 260 is slidably engaged with the first slide rail 250.

[0058] The positioning seat 242 is fixedly connected to the second slider, and the second slider slides in cooperation with the second slide rail.

[0059] For ease of description, let's assume that the multiple buffer stations in the fixture module are arranged in the order in which products are placed (i.e., ... Figure 3 The buffer stations (from right to left in the diagram) are respectively labeled as the first buffer station, the second buffer station, ..., the nth buffer station, where n is a natural number greater than 1.

[0060] When no material is being loaded, the PPU handling assembly 300 is in its initial position, and the first buffer station is in a position waiting for material to be loaded.

[0061] When feeding is required, a batch of products is placed in the vibratory feeder 110. The vibratory feeder 110 will continuously output individual products to the feeding station of the linear vibratory track 120. When there is a product on the feeding station of the linear vibratory track 120, the PPU handling component 300 will move to transport the product to the first buffer station on the fixture module.

[0062] Subsequently, the PPU transport assembly 300 is reset to its initial position, and the first X-axis motion platform 220 moves along... Figure 1 The solid arrow in the middle indicates that the PPU moving in the X direction for a preset distance places the second buffer station in a waiting position for loading. When there is another product on the loading station of the linear vibrating track 120, the PPU transport assembly 300 moves again, transporting the product to the second buffer station on the fixture module. Subsequently, the PPU transport assembly 300 returns to its initial position, and the first X-axis motion platform 220 moves along... Figure 1 The solid arrow in the middle indicates that the X-axis moves a preset distance, so that the third buffer station is in a position waiting for material to be loaded.

[0063] This process is repeated until all buffer stations on the fixture module have been loaded.

[0064] Afterwards, the first X-axis motion platform 220 along... Figure 1 The solid arrow in the middle indicates that the X-direction re-moves to the handling position of the loading and handling assembly 400, waiting for the loading and handling assembly 400 to handle it.

[0065] In some embodiments of this application, see Figure 1 The loading and handling component 400 is located on one side of the first X-axis motion platform 220 and has multiple handling stations. Each handling station corresponds to a buffer station 231, which is used to simultaneously handle multiple products to be loaded on multiple buffer stations 231.

[0066] To enable the material handling assembly 400 to acquire multiple products and transport them to subsequent workstations for loading, see [link / reference]. Figures 4 to 6 The loading and handling assembly 400 includes a loading frame 410, a second X-axis motion platform 420, a Z-axis motion platform 430, and an acquisition unit 440.

[0067] See back Figure 1 and combined Figure 4 The loading frame 410 is fixed to the fixed platform 500, serving as the base of the loading and handling assembly 400.

[0068] The second X-axis motion platform 420 is mounted on the loading frame 410, the Z-axis motion platform 430 is mounted on the second X-axis motion platform 420, and the acquisition unit 440 is mounted on the Z-axis motion platform 430 to realize the X-axis and Z-axis motion of the acquisition unit 440. The acquisition unit 440 has multiple handling stations for handling products from multiple buffer stations.

[0069] The Z-axis motion platform 430 is used to adjust the Z-axis distance between the acquisition unit 440 and the buffer station. Combined with the second X-axis motion platform 420, it adjusts the loading and conveying component 400 to accurately align with the conveying position so as to accurately acquire multiple products on multiple buffer stations. After acquiring multiple products, the second X-axis motion platform 420 moves, and the multiple products are moved along the X-axis to, for example, a subsequent loading station.

[0070] In some embodiments of this application, the structural arrangement of the second X-axis motion platform 420 and the Z-axis motion platform 430 is similar to that of the first X-axis motion platform 220, and will not be described in detail here.

[0071] In some embodiments of this application, in order to obtain multiple products, see [link to relevant documentation]. Figure 5 The acquisition unit 440 may include a base 441 and a plurality of acquisition parts 442, and the base 441 may be a mounting side plate.

[0072] Multiple acquisition units 442 are arranged along the X direction on the mounting side plate, and the number of multiple acquisition units 442 is the same as the number of multiple buffer stations. One acquisition unit 442 corresponds to one buffer station and is used to acquire the product on the corresponding buffer station.

[0073] In some embodiments of this application, see Figure 5 The acquisition unit 442 includes a mounting component 4421, a Z-axis slide 4426, a sliding block 4422, an elastic reset component, and a material picking unit 4423.

[0074] Mounting component 4421 and Z-axis slide rail 4426 are both fixedly mounted on one side of the fixed side plate.

[0075] The sliding block 4422 slides and engages with the Z-axis slide rail 4426 and is connected to the mounting part 4421. The picking part 4423 is fixed to the sliding block 4422, and the free end of the picking part 4423 is used to pick up the product to be loaded on the buffer station 231.

[0076] In some embodiments of this application, the material handling part 4423 can be a gripper, which is used to grasp the product when it is necessary to handle the product.

[0077] In some embodiments of this application, see Figure 6 The material handling unit 4423 can be a vacuum adsorption port, and it is also provided with a vacuum channel (not shown). The vacuum channel is connected to a vacuum pump (not shown) and the vacuum adsorption port respectively. The vacuum pump evacuates the vacuum channel so that the vacuum adsorption port can adsorb the product on the corresponding buffer station. Compared with gripping, the adsorption method avoids damage or scratches to the product.

[0078] When the loading and handling assembly 400 moves multiple products to the subsequent loading station, the vacuum pump is used to release the products from the vacuum suction port.

[0079] In some embodiments of this application, an elastic reset member is disposed between the mounting member 4421 and the sliding block 4422. Thus, due to the provision of the elastic reset member, the material taking part 4423 can flexibly contact the product on the buffer station, avoiding hard contact with the product and causing damage to the product.

[0080] (1) When no material is picked up, the elastic reset member is in the initial position and the picking part 4423 is also in the initial position; (2) When the picking part 4423 picks up the product, the picking part 4423 contacts the product. At the moment of contact, the product will apply a small external force to the elastic reset member, causing the sliding block 4422 to move along the Z-direction slide 4426 and compress the elastic reset member; (3) After the product is picked up, the elastic force of the elastic reset member is restored, so that the picking part 4423 returns to the initial position.

[0081] In some embodiments of this application, see Figure 5 and Figure 6 The elastic reset component is a spring 4425.

[0082] To achieve the connection between the mounting component 4421 and the sliding block 4422, and to enable the sliding block 4422 to slide along the Z-axis slide rail 4426, see [reference needed]. Figure 5 and Figure 6The acquisition part 442 also includes a connecting rod 4424. One end of the connecting rod 4424 has a limiting block. The mounting member 4421 has a Z-direction through hole. The size of the limiting block is larger than the opening size of the through hole. Therefore, when the other end of the connecting rod 4424 extends through the through hole, the other end of the connecting rod 4424 is limited by the mounting member 4421. An external thread is formed on the outer side wall of the other end of the connecting rod.

[0083] See Figure 6 The sliding block 4422 has a receiving groove 4427 near the top of the mounting part 4421, and a connecting groove 4428 is formed on the bottom wall of the receiving groove 4427. The inner wall of the connecting groove 4428 is provided with an internal thread, and the external thread on the outer wall of the connecting rod 4424 is threadedly connected to the internal thread.

[0084] Spring 4425 is sleeved on connecting rod 4424, with one end of spring 4425 abutting against mounting part 4421 and the other end extending into receiving groove 4427 and abutting against the bottom wall of receiving groove 4427.

[0085] Therefore, when the material taking part 4423 is subjected to force, the force is transmitted to the spring 4425 through the sliding block 4422 and the connecting rod 4424, and the spring 4425 is compressed. When the external force is lost on the material taking part 4423, the elastic restoring force of the spring 4425 pushes the sliding block 4422 and the connecting rod 4424 back to the initial position.

[0086] The multi-product feeding device involved in this application can not only feed multiple products at the same time, but also has simple structure and low cost of each component.

[0087] In addition, the components can be arranged compactly to improve space utilization.
