Description

Technical Field

[0001] This utility model relates to the field of battery processing technology, and in particular to a feeding device and a battery production line. Background Technology

[0002] When loading sheet-like workpieces such as battery base plates or electrode sheets, a robotic arm typically picks up the top sheet from a hopper containing multiple base plates or electrode sheets and places it on the next processing station. However, because the base plates or electrode sheets are very thin and carry static electricity, they often overlap and stick together, leading to waste of raw materials and potentially affecting the production quality of the battery. Utility Model Content

[0003] The main purpose of this invention is to provide a feeding device and a battery production line, which aims to reduce the risk of stacking when the feeding device picks up sheet-like workpieces.

[0004] To achieve the above objectives, this utility model proposes a feeding device and a battery production line. The feeding device includes a hopper and a picking mechanism; the hopper has a picking port and a bottom plate, the bottom plate being disposed opposite to the picking port in the axial direction of the picking port, and a receiving cavity being formed between the picking port and the bottom plate; the picking mechanism includes a driving member and a suction assembly, the driving member being connected to the suction assembly and driving the suction assembly to pass through the picking port to extend into or out of the hopper, the bottom of the suction assembly being arc-shaped, the arc arching towards the bottom plate.

[0005] This utility model's technical solution incorporates a hopper with a dispensing port, facilitating the placement and removal of workpieces. The hopper also features a base plate positioned axially opposite the dispensing port, forming a receiving cavity between the dispensing port and the base plate. This cavity can accommodate multiple workpieces, and the base plate can support them, reducing the risk of workpiece deformation. Furthermore, a dispensing mechanism, comprising a drive component and a suction assembly, is incorporated. The drive component connects to the suction assembly and drives it to extend into or out of the hopper through the dispensing port. This achieves the automatic removal and placement of workpieces from and from the hopper.

[0006] By setting the bottom of the suction component in an arc shape, with the arc arching towards the base plate, the two ends of the workpiece are tilted away from the base plate after the suction component picks up the workpiece. This facilitates the separation of the workpiece closest to the pick-up port from other workpieces, reducing the risk of workpieces overlapping during the workpiece picking process.

[0007] In one embodiment, the suction assembly includes a mounting base, a first suction cup, and a plurality of second suction cups. The mounting base is convexly connected to the driving component. The first suction cup is mounted on the mounting base. The plurality of second suction cups are mounted on the mounting base and are respectively disposed on opposite sides of the first suction cup. The line connecting the bottom center of the plurality of second suction cups and the bottom center of the first suction cup is arranged in an arc shape.

[0008] With this configuration, when the suction component picks up the workpiece, the middle of the workpiece is closer to the bottom plate, while the part that is attracted by the second suction cup is tilted away from the bottom plate. This makes it easier to separate the attracted workpiece from other workpieces and reduces the risk of stacking during the material handling process.

[0009] In one embodiment, the first suction cup includes an elastic element and a suction cup body, one end of the elastic element being mounted on the mounting base; the suction cup body is connected to the end of the elastic element away from the mounting base.

[0010] This configuration allows the suction cup body of the first suction cup to be closer to the base plate than the second suction cup. Furthermore, it provides good cushioning force when picking up workpieces, reducing the risk of workpiece damage.

[0011] In one embodiment, the central angle corresponding to the arc is θ, where 120°≤θ≤160°.

[0012] This design facilitates the picking up of workpieces while also causing the edges of the workpieces to be noticeably raised, allowing the workpieces in contact with the picking components to be clearly separated from other workpieces, thus reducing the risk of stacking.

[0013] In one embodiment, 145°≤θ≤155°.

[0014] This setting further reduces the risk of chip stacking.

[0015] In one embodiment, the feeding device further includes a blower mechanism, which is disposed on the side of the hopper and communicates with the hopper.

[0016] This setup removes at least some of the static electricity between adjacent workpieces.

[0017] In one embodiment, the feeding device further includes a scraping mechanism, at least a portion of which covers the feeding port.

[0018] With this setup, it is possible to scrape off workpieces that are not directly picked up by the suction component from multiple overlapping workpieces.

[0019] In one embodiment, the scraping mechanism includes a bracket and a brush assembly. One of the bracket and the hopper is provided with a sliding hole, and the other is provided with a slider. The slider is disposed in the sliding hole, and the extension direction of the sliding hole is set at an angle to the opening direction of the material dispensing port. The brush assembly is disposed on the bracket and covers part of the material dispensing port.

[0020] This setup allows for adjustment of the friction between the brush and the workpiece, ensuring a good peeling effect on workpieces not directly picked up by the suction component while preventing workpieces directly picked up by the suction component from falling off.

[0021] In one embodiment, the brush assembly includes a rotating shaft and a brush body. The rotating shaft is rotatably mounted on the bracket, and the extension direction of the sliding hole and the opening direction of the feed port are both set at an angle to the extension direction of the rotating shaft. The brush body is mounted on the rotating shaft, and at least a portion of the brush body covers a portion of the feed port.

[0022] This configuration allows overlapping workpieces to make extensive contact with the brush body as they move along the opening direction of the feeding port under the drive of the feeding mechanism, and enables the brush body to automatically rotate around the axis, thereby reducing the need for a drive component to rotate the brush body.

[0023] In one embodiment, the depth of the brush body extending into the feed inlet in the extending direction of the sliding hole is D, where 0 < D ≤ 4 mm.

[0024] This configuration ensures that overlapping workpieces are brushed off while preventing workpieces in direct contact with the suction component from being brushed off by the brush body, thus achieving the effect that the suction component can only pick up one workpiece at a time.

[0025] In one embodiment, the hopper further includes at least two side plates, which are arranged opposite to each other and are slidably disposed on the bottom plate, and can move closer to or further away from each other.

[0026] This configuration allows for changing the distance between the two side plates, thus accommodating workpieces of different sizes and improving the versatility of the hopper.

[0027] In one embodiment, the base plate is provided with a plurality of positioning holes, the arrangement direction of the plurality of positioning holes is the same as the arrangement direction of the two side plates, and the side plates are selectively installed in at least one of the positioning holes by means of connectors.

[0028] With this setup, a stable connection between the two side plates and the base plate can be achieved by inserting the connectors into the positioning holes.

[0029] This utility model also proposes a battery production line, including the above-mentioned feeding device. Attached Figure Description

When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0044] The battery structure mainly includes the cell, casing, and base plate. The base plate is located at the bottom inside the casing, and the cell is placed on the base plate, which is used to fix the cell's position. Currently, in the battery production process, when loading sheet-like workpieces such as base plates or electrode sheets, a robotic arm is usually used to pick up the top sheet from a hopper containing multiple base plates or electrode sheets and place it on the next processing station. However, because the base plates or electrode sheets are very thin and carry static electricity, they often overlap and stick together, leading to waste of raw materials and potentially affecting the battery's production quality.

[0045] In order to improve the problem of overlapping pieces when picking up sheet-shaped workpieces in related technologies, this utility model proposes a feeding device.

[0046] Please refer to the reference. Figure 1 and Figure 2 As shown, in one embodiment of the present invention, the feeding device includes a hopper 100 and a feeding mechanism 200; the hopper 100 has a feeding port 101 and a bottom plate 110, the bottom plate 110 is disposed opposite to the feeding port 101 in the axial direction of the feeding port 101, and a receiving cavity is formed between the feeding port 101 and the bottom plate 110; the feeding mechanism 200 includes a driving member 210 and a suction assembly 220, the driving member 210 is connected to the suction assembly 220, and drives the suction assembly 220 to pass through the feeding port 101 to extend into or out of the hopper 100, the bottom of the suction assembly 220 is arc-shaped, and the arc arches towards the bottom plate 110.

[0047] The hopper 100 refers to a component for placing workpieces 500 to be retrieved. The hopper 100 has a receiving cavity for placing the workpieces 500. This receiving cavity can be composed of a base plate 110 and side plates 120 connected to the base plate 110. In one example, the side plates 120 are arranged in a cylindrical, cuboid, or other shape. The shape formed by the side plates 120 can be adapted to the shape of the actual workpiece 500. Alternatively, in other examples, to save costs, only two side plates 120 may be provided, arranged opposite each other, so that the oppositely arranged side plates 120 and the base plate 110 together form a space for placing the workpiece 500. The side plates 120 can be flat or curved, etc. In this invention, the workpiece 500 is a sheet-like workpiece 500, such as an electrode sheet or a base plate. To facilitate the placement of workpiece 500, the hopper 100 has an opening for the workpiece 500 to enter and exit the receiving cavity, namely a pick-up port 101. The shape of the pick-up port 101 can be circular, rectangular, or other shapes. The pick-up port 101 of the hopper 100 can open upwards or to the side. It should be noted that the base plate 110 refers to the component opposite to the pick-up port 101 in the axial direction. For example, when the pick-up port 101 opens upwards, the base plate 110 is the bottommost plate in the hopper 100. When the pick-up port 101 opens to the left, the base plate 110 is the rightmost plate in the hopper 100.

[0048] The material handling mechanism 200 refers to the mechanism used to pick up the sheet-like workpiece 500. This mechanism includes a drive component 210 and a suction assembly 220. The drive component 210 is connected to the suction assembly 220 and drives the suction assembly 220 through the material handling port 101 to extend into or out of the material bin 100. The drive component 210 can be a linear motor, a robotic arm, or a gear and rack assembly, etc. The suction assembly 220 refers to the actuating component in the material handling mechanism 200 used to pick up the sheet-like workpiece 500. The suction assembly 220 can include a suction cup or a mounting component for mounting the suction cup. There can be one, two, or more suction cups. When there is one suction cup, it can be set to be larger, thereby facilitating the application of a larger suction force to the workpiece 500 and ensuring that the workpiece 500 is picked up by the suction cup. The bottom of the suction assembly 220 is arc-shaped. This means that when there is one suction cup, the bottom of the suction cup can be set to be arc-shaped, with the bottom surface arching towards the base plate 110. Alternatively, the bottom of the suction assembly 220 is arc-shaped when there are multiple suction cups, arranged at an angle to the opening direction of the feeding port 101, with the bottoms of the multiple suction cups forming an arc. By making the bottom of the suction assembly 220 arc-shaped, when the suction assembly 220 picks up the workpiece 500 closest to the feeding port 101 in the material bin 100, the two ends of the workpiece 500 tend to tilt away from the base plate 110, thus facilitating the separation of the workpiece 500 closest to the feeding port 101 from other workpieces 500, thereby reducing the risk of overlapping when the picking mechanism 200 picks up the workpiece 500.

[0049] This utility model's technical solution, by setting up a hopper 100 with a material inlet 101, facilitates the placement and removal of workpieces 500 from the hopper 100. The hopper 100 also has a base plate 110 positioned opposite the material inlet 101 along its axial direction. A receiving cavity is formed between the material inlet 101 and the base plate 110, which can accommodate multiple workpieces 500. The base plate 110 can support multiple workpieces 500, reducing the risk of workpiece deformation. By setting up a material handling mechanism 200, which includes a drive member 210 and a suction assembly 220, and driving the suction assembly 220 to pass through the material inlet 101 to extend into or out of the hopper 100, the system can automatically remove workpieces 500 from and automatically place them into the hopper 100. By arranging the bottom of the suction component 220 in an arc shape, with the arc arching towards the base plate 110, after the suction component 220 picks up the workpiece 500, both ends of the workpiece 500 are tilted away from the base plate 110. This facilitates the separation of the workpiece 500 closest to the feeding port 101 from other workpieces 500, reducing the risk of workpieces 500 overlapping during the feeding process.

[0050] Please refer to the reference. Figure 1 and Figure 2 In some embodiments of this utility model, the suction component 220 includes a mounting base 221, a first suction cup 222, and a plurality of second suction cups 223. The mounting base 221 is connected to the driving component 210. The first suction cup 222 is mounted on the mounting base 221. The plurality of second suction cups 223 are mounted on the mounting base 221 and are respectively disposed on opposite sides of the first suction cup 222. The line connecting the bottom center of the plurality of second suction cups 223 and the bottom center of the first suction cup 222 is arc-shaped.

[0051] Mounting base 221 refers to the base used to mount the first suction cup 222 and multiple second suction cups 223. The mounting base 221 can be rectangular, circular, rectangular, or circular. The mounting base 221 and the driving component 210 can be connected by screws, a gear and rack assembly, or a linkage assembly, as long as the driving component 210 can drive the mounting base 221 to move along the opening direction of the feeding port 101.

[0052] The first suction cup 222 refers to the suction cup located in the middle relative to the second suction cup 223. The first suction cup 222 can be located in the middle of the mounting base 221, or in other positions near the middle of the mounting base 221. There can be one, two, or more first suction cups 222.

[0053] The second suction cup 223 is a suction cup located on either side of the first suction cup 222, relative to the first suction cup 222. There can be two second suction cups 223, one on each side of the first suction cup 222. Alternatively, there can be three, four, five, six, seven, eight, or more second suction cups 223, distributed on both sides of the first suction cup 222, thus allowing the second suction cups 223 to be symmetrically or approximately symmetrically arranged with respect to the first suction cup 222.

[0054] The mounting base 221 is connected to the drive component 210. The first suction cup 222 and multiple suction cups are all mounted on the mounting base 221. This allows the drive component 210 to drive the first suction cup 222 and multiple second suction cups 223 to move simultaneously in the opening direction of the material pick-up port 101 by simply driving the mounting base 221 to move in the opening direction of the material pick-up port 101, thereby improving the driving efficiency. By distributing multiple second suction cups 223 on opposite sides of the first suction cup 222, and with the line connecting the bottom center of the multiple second suction cups 223 and the bottom center of the first suction cup 222 forming the aforementioned arc shape, the suction cups of the suction assembly 220 are arranged in an arc shape. This makes the position of the first suction cup 222 closer to the bottom plate 110 of the hopper 100 relative to the position of the second suction cups 223. As a result, when the suction assembly 220 picks up the workpiece 500, the middle part of the workpiece 500 is closer to the bottom plate 110, while the part adsorbed by the second suction cup 223 is tilted away from the bottom plate 110. This facilitates the separation of the adsorbed workpiece 500 from other workpieces 500, reducing the risk of stacking during the material handling process.

[0055] Please refer to the reference. Figure 1 and Figure 2 In some embodiments of this utility model, the first suction cup 222 includes an elastic element 2221 and a suction cup body 2222. One end of the elastic element 2221 is mounted on the mounting base 221; the suction cup body 2222 is connected to the end of the elastic element 2221 that is away from the mounting base 221.

[0056] The elastic element 2221 can be an elastic component such as a spring or a sheet.

[0057] The suction cup body 2222 refers to the part used to directly adsorb the workpiece 500.

[0058] By mounting one end of the elastic element 2221 to the mounting base 221 and connecting the other end to the suction cup body 2222, the suction cup body 2222 can provide a spring force towards the base plate 110 when no pressure is applied to the workpiece 500. This makes the suction cup body 2222 of the first suction cup 222 closer to the base plate 110 relative to the second suction cup 223. On the other hand, it can provide good cushioning force when picking up the workpiece 500, reducing the risk of damage to the workpiece 500.

[0059] In some embodiments of this utility model, such as Figure 2 As shown, the central angle corresponding to the arc is θ, where 120°≤θ≤160°.

[0060] The central angle θ corresponding to the arc can be 120°, 121°, 122°, 123°, 124°, 125°, 126°, 127°, 128°, 129°, 130°, 131°, 132°, 133°, 134°, 135°, 136°, 137°, 138°, 139°, 140°, 141°, 142°, 143°, 144°, 145°, 146°, 147°, 148°, 149°, 150°, 151°, 152°, 153°, 154°, 155°, 156°, 157°, 158°, 159°, or 160°, etc.

[0061] If the central angle corresponding to the arc is less than 120°, the suction component 220 may have difficulty picking up the workpiece 500; if the central angle corresponding to the arc is greater than 160°, after the suction component 220 picks up the workpiece 500, the end of the workpiece 500 in contact with the suction component 220 will not be significantly raised, making it difficult to achieve the effect of separation from other workpieces 500.

[0062] By setting the central angle θ corresponding to the arc to 120°≤θ≤160°, it is not only convenient to pick up the workpiece 500, but also to make the edge of the workpiece 500 obviously raised, so that the workpiece 500 in contact with the picking component 220 can be clearly separated from other workpieces 500, thereby reducing the risk of stacking.

[0063] Furthermore, in some embodiments of this utility model, 145°≤θ≤155°.

[0064] The central angle θ corresponding to the arc can be 145°, 146°, 147°, 148°, 149°, 150°, 151°, 152°, 153°, 154° or 155°, etc.

[0065] By setting the central angle θ corresponding to the arc to 145°≤θ≤155°, it is not only easier to pick up the workpiece 500, but also makes the edge of the workpiece 500 more noticeable when it is raised, so that the workpiece 500 in contact with the picking component 220 can be more clearly separated from other workpieces 500, thereby further reducing the risk of stacking.

[0066] like Figure 1 As shown, in some embodiments of this utility model, the feeding device further includes a blower mechanism 300, which is located on the side of the hopper 100 and communicates with the hopper 100.

[0067] The blower mechanism 300 is a device used to blow air onto the workpieces 500 in the hopper 100, thereby reducing the electrostatic interaction between two adjacent workpieces 500. To achieve communication between the blower mechanism 300 and the hopper 100, ventilation holes can be provided on the side plate 120. Alternatively, when the hopper 100 has two opposing side plates 120, a portion of the blower mechanism 300 can be offset from the side plates 120 of the hopper 100 to achieve communication between the blower mechanism 300 and the hopper 100. The blower mechanism 300 can be in a normally open state. Alternatively, a sensor is provided inside the hopper 100, and the sensor is electrically connected to the blower mechanism 300. The sensor detects whether the workpieces 500 being attracted overlap; the sensor can be a photoelectric sensor or a distance sensor, etc. When the sensor detects that the workpieces 500 attracted by the suction assembly 220 are in an overlapping state, the sensor sends a signal to the blower mechanism 300, thereby controlling the blower mechanism 300 to open.

[0068] By placing the blower mechanism 300 on the side of the hopper 100 and communicating with the hopper 100, the blower mechanism 300 can blow air onto the workpieces 500 in the hopper 100, thereby removing at least part of the static electricity between adjacent workpieces 500, and thus reducing the risk of two adjacent workpieces 500 overlapping each other during the process of picking up workpieces 500.

[0069] like Figure 1 As shown, in some embodiments of this utility model, at least two blower mechanisms 300 may be provided, with the at least two blower mechanisms 300 respectively located on opposite sides of the material hopper 100. This arrangement allows air to be blown onto the workpiece 500 from both opposite sides of the material hopper 100, improving the effect of eliminating static electricity between two overlapping workpieces 500.

[0070] Please refer to the reference. Figure 1 and Figure 3 In some embodiments of this utility model, the feeding device further includes a scraping mechanism 400, which covers the material inlet 101.

[0071] The scraping mechanism 400 is used to scrape away workpieces 500 that are not directly picked up by the suction component 220. The scraping mechanism 400 may include scrapers, scraper blades, or brushes disposed beside the material handling channel, and may also include other mounting components for mounting scrapers, scraper blades, or brushes.

[0072] By covering part of the feeding port 101 with the scraping mechanism 400, when the workpiece 500 in the feeding port 101 passes through the scraping mechanism 400, the scraping mechanism 400 can scrape off the workpiece 500 that is not directly picked up by the suction component 220 from the multiple overlapping workpieces 500, while the workpiece 500 that is directly picked up by the suction component 220 can not fall off under the suction action of the suction component 220. Therefore, the overlapping workpieces 500 can be separated, reducing the risk of overlapping during the picking of workpieces 500.

[0073] In some embodiments of this utility model, at least two scraping mechanisms 400 may be provided, with each of the at least two scraping mechanisms 400 respectively located on opposite sides of the hopper 100, and each of the at least two scraping mechanisms 400 covering a portion of the material inlet 101. This arrangement provides frictional force to the workpieces 500 from opposite sides of the hopper 100, thereby increasing the probability of brushing off workpieces 500 that are not directly in contact with the suction assembly 220 from among the overlapping workpieces 500.

[0074] Please refer to the reference. Figure 1 and Figure 3 In some embodiments of this utility model, the scraping mechanism 400 includes a bracket 410 and a brush assembly 420. One of the bracket 410 and the hopper 100 is provided with a sliding hole 411, and the other is provided with a slider. The slider is disposed in the sliding hole 411, and the extending direction of the sliding hole 411 is set at an angle to the opening direction of the feeding port 101. The brush assembly 420 is disposed on the bracket 410, and at least part of the brush assembly 420 covers part of the feeding port 101.

[0075] A sliding hole 411 is a hole through which a slider slides. Therefore, a sliding hole 411 is typically elongated, such as a rectangular or oblong hole. A slider is a component that can slide within the sliding hole 411. The sliding hole 411 can be mounted on a bracket 410, thus providing a slider on the hopper 100. Moving the bracket 410 along the extension direction of the sliding hole 411 allows the slider to slide relative to the sliding hole 411, effectively guiding the movement of the bracket 410. The extension direction of the sliding hole 411 can be perpendicular to the opening direction of the feed port 101, or at an acute or obtuse angle. For example, when the opening direction of the feed port 101 is upward, the extension direction of the sliding hole 411 can extend laterally or longitudinally.

[0076] The brush assembly 420 can be cylindrical or flat, etc.

[0077] By placing the brush assembly 420 on the bracket 410 and at least partially covering the material inlet 101, the brush assembly 420 can effectively hold the workpiece 500 during the material handling process. Therefore, there is friction between the brush and the workpiece 500. When the workpiece 500 moves, the brush can effectively hinder the workpiece 500 under the action of its friction, so as to prevent the workpiece 500 from continuing to move with the suction assembly 220. This achieves a good peeling effect on the workpiece 500 that is not directly picked up by the suction assembly 220, reducing the risk of stacking during the picking of the workpiece 500.

[0078] In addition, by providing a sliding hole 411 in one of the bracket 410 and the hopper 100, and a slider in the other, with the extension direction of the sliding hole 411 forming an angle with the extension direction of the feeding port 101, the brush assembly 420 can move along the bracket 410 in the extension direction of the sliding hole 411, that is, in the direction forming an angle with the feeding direction. This can change the holding force between the brush assembly 420 and the workpiece 500, thereby achieving the effect of adjusting the friction between the brush and the workpiece 500. This ensures that while the workpiece 500 not directly picked up by the suction assembly 220 can have a good peeling effect, the workpiece 500 directly picked up by the suction assembly 220 is also not easy to fall off.

[0079] Please refer to the reference. Figure 1 and Figure 3 In some embodiments of this utility model, the brush assembly 420 includes a rotating shaft 421 and a brush body 422. The rotating shaft 421 is rotatably mounted on the bracket 410. The extending direction of the sliding hole 411 and the opening direction of the feed port 101 are both set at an angle to the extending direction of the rotating shaft 421. The brush body 422 is mounted on the rotating shaft 421, and at least part of the brush body 422 covers part of the feed port 101.

[0080] The rotating shaft 421 is a component that provides support for the rotation of the brush body 422. The extending direction of the rotating shaft 421 can be at an acute, right, or obtuse angle to the extending direction of the sliding hole 411. Similarly, the extending direction of the rotating shaft 421 can be at an acute, right, or obtuse angle to the opening direction of the material inlet 101. For example, when the opening direction of the material inlet 101 is upward and the extending direction of the sliding hole 411 is left-right, the extending direction of the rotating shaft 421 can be along the front-back direction. This arrangement facilitates a larger contact area between the brush body 422 and the workpiece 500, thus making it easier to scrape off overlapping workpieces 500.

[0081] The brush body 422 is mounted on the rotating shaft 421. The brush body 422 can be flat or cylindrical. When the brush body 422 is flat, one edge of the brush body 422 is connected to the outer wall of the rotating shaft 421, and the opposite edge extends away from the rotating shaft 421. When the brush body 422 is cylindrical, the brush body 422 can be fitted over the rotating shaft 421.

[0082] By rotating the shaft 421 to the bracket 410, and setting the extension direction of the sliding hole 411 and the opening direction of the feeding port 101 at an angle to the extension direction of the shaft 421, and setting the brush body 422 on the shaft 421, with at least a portion of the brush body 422 covering the feeding port 101, the overlapping workpieces 500 can make extensive contact with the brush body 422 when moving along the opening direction of the feeding port 101 under the drive of the feeding mechanism 200, and can drive the brush body 422 to automatically rotate around the shaft 421, thereby reducing the need for a drive component to drive the brush body 422 to rotate.

[0083] In some embodiments of this utility model, the depth of the brush body 422 extending into the feed inlet 101 in the extending direction of the sliding hole 411 is D, where 0 < D ≤ 4 mm.

[0084] The depth D of the brush body 422 extending into the feed inlet 101 in the extending direction of the sliding hole 411 can be 0.5mm, 1mm, 1.5mm, 2mm, 2.5mm, 3mm, 3.5mm or 4mm, etc.

[0085] If the depth of the brush body 422 extending into the material inlet 101 in the extension direction of the sliding hole 411 is less than or equal to 0, there is no friction between the brush body 422 and the workpiece 500, so the brush body 422 cannot brush down the overlapping workpieces 500; if the depth of the brush body 422 extending into the material inlet 101 in the extension direction of the sliding hole 411 is greater than 4 mm, the friction between the brush body 422 and the workpiece 500 is too large, so the brush body 422 will also scrape down the workpieces 500 that are in direct contact with the suction component 220, making it difficult to pick up the workpieces 500.

[0086] By setting the depth of the brush body 422 extending into the material inlet 101 in the extension direction of the sliding hole 411 to be greater than 0 and not less than 4 mm, the friction between the brush body 422 and the workpiece 500 is made more suitable. This ensures that overlapping workpieces 500 are brushed off, while preventing workpieces 500 that are in direct contact with the suction component 220 from being brushed off by the brush body 422. This achieves the effect that the suction component 220 can only pick up one workpiece 500 at a time.

[0087] like Figure 1 As shown, in some embodiments of this utility model, the hopper 100 further includes at least two side plates 120, which are arranged opposite to each other and are slidably disposed on the bottom plate 110, and can move closer to or further away from each other.

[0088] The side plate 120 can be flat or U-shaped. There can be two, three, or more side plates 120. At least two side plates 120 are arranged opposite each other to limit the opposite sides of the workpiece 500, thereby improving the stability of the workpiece 500 within the hopper 100 and reducing the risk of displacement. When the side plate 120 slides on the base plate 110, one of the side plate 120 and the base plate 110 can be provided with a groove, and the other with a guide rail. Alternatively, neither the side plate 120 nor the base plate 110 can be provided with a groove or guide rail; the bottom surface of the side plate 120 contacts the flat plate of the base plate 110, and the side plate 120 can slide relative to the base plate 110 under external force. Of course, in other examples, a screw and nut structure can be used, with the screw rotatably mounted on the base plate 110, the nut threaded onto the screw, and the side plate 120 connected to the nut. By rotating the screw, the side plate 120 can move relative to the base plate 110.

[0089] By sliding at least two side plates 120 onto the base plate 110 and allowing them to move closer or further apart, the distance between the two side plates 120 can be changed, thereby adapting to the placement of workpieces 500 of different sizes and improving the versatility of the hopper 100.

[0090] In some embodiments of this utility model, the base plate 110 is provided with a plurality of positioning holes, the arrangement direction of the plurality of positioning holes is the same as the arrangement direction of the two side plates 120, and the side plates 120 are selectively installed in at least one positioning hole by means of connectors.

[0091] Positioning holes are holes through which connectors pass, thereby fixing the side plate 120 and the base plate 110 together. Positioning holes can be snap-fit ​​holes or threaded holes. Corresponding connectors can be snap-fit ​​devices or bolts, etc.

[0092] By setting multiple positioning holes on the base plate 110, and the arrangement direction of the multiple positioning holes is the same as the arrangement direction of the two side plates 120, each of the two side plates 120 can choose one of the multiple positioning holes to connect with it through a connector. Thus, after adjusting the distance between the two side plates 120, a stable connection between the two side plates 120 and the base plate 110 can be achieved by inserting the connector into the positioning hole.

[0093] In other embodiments, the base plate 110 may also be provided with a magnetic strip, the extension direction of which is the same as the arrangement direction of the two side plates 120; the side plates 120 are provided with magnetic blocks, which are magnetically connected to the magnetic strip. With this configuration, after the distance between the two side plates 120 is adjusted, the connection between the side plates 120 and the base plate 110 is achieved directly through the magnetic connection between the magnetic blocks and the magnetic strip.
