Description

Technical Field

[0001] This invention relates to the field of component feeding technology, and in particular to a receiving mechanism, receiving method and feeding device. Background Technology

[0002] During the processing or testing of semiconductors and electronic components, components need to be supplied to corresponding sorting and testing devices via a feeding device. For example, during IC chip testing, the feeding device supplies the components to the loading mechanism. After the loading mechanism inputs the IC chip, the main motor drives the rotary table to rotate, and the control system drives the picking mechanism to lift and lift, picking up the IC chip and placing it at various workstations for performance testing. After receiving the component, the receiving mechanism transports it to the loading position according to the picking requirements. However, existing feeding devices use vibratory feeders for vibration feeding. Due to the small mass and size of the chips, when the receiving mechanism moves away from or detaches from the vibratory feeder, it cannot obtain effective forward momentum, resulting in slow movement and the chip easily getting stuck in the channel, unable to reach the loading position.

Detailed Implementation

[0059] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of the present invention, but not all embodiments.

[0060] In this embodiment, "several" and "more than" refer to two or more. In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0061] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0062] The receiving mechanism in this embodiment is used to receive and arrange the components for supply to the downstream picking mechanism, facilitating rapid picking. The components include, but are not limited to, small-sized and small-weight components such as IC chips and electronic components.

[0063] <Example 1>

[0064] like Figures 1 to 3 As shown, the receiving mechanism 100 in this embodiment includes a receiving channel 110, a pushing chamber 120, and a first fluid channel. The receiving channel 110 is used to receive the material 10. The material enters the receiving channel 110 through the inlet. At least one receiving channel 110 is provided, and the specific number is modified according to the feeding and picking mechanism. The shape, structure, and size of the receiving channel can be configured according to the type, size, shape, and other parameters of the material, and are not limited here, as long as the material can move in the receiving channel. The pushing chamber 120 is disposed in the receiving channel 110, which passes through the pushing chamber 120. The pushing chamber 120 is a cavity formed in the receiving channel 110. The material 10 can enter the pushing chamber 120 through the receiving channel 110. The auxiliary power provided by the pushing chamber 120 can prevent the material 10 from stagnating on the receiving channel 110 or accelerate the movement of the material 10 on the receiving channel 110. At the same time, the confinement of the cavity on the material can prevent the material from being forced out of the receiving channel 110. The first fluid channel is connected to the pushing chamber 120. The first fluid channel is an airflow channel that introduces fluid into the pushing chamber 120 and inputs it into the receiving channel 110 to push the material to move. The first fluid channel can selectively provide positive pressure or no pressure according to the movement of the material in the receiving channel. The first fluid channel is connected to an external air source, which provides airflow. This is a conventional technical means in the art and will not be described in detail.

[0065] In this embodiment, the material components 10 enter the receiving channel 110 one by one along the feeding direction X. Each component possesses a certain kinetic energy and moves forward within the receiving channel 110, with subsequent components pushing the preceding components. As the number of components in the receiving channel 110 increases, subsequent components can no longer push the preceding components. The positive pressure airflow introduced through the first fluid channel assists in pushing the components. In this embodiment, the receiving channel 110 is a straight channel, facilitating the movement of the material components 10 and avoiding increased resistance to forward movement due to channel curvature.

[0066] like Figures 1 to 3 As shown, furthermore, at least a portion of the receiving channel 110 is covered by the pushing cavity 120, and the loading portion of the receiving channel 110 is located outside the pushing cavity. The loading portion is used for the picking mechanism 400 (see...). Figure 19 The material is picked up and exposed outside the push cavity 120 to avoid interference with the material picking process and facilitate the picking mechanism. The feeding section can hold at least one material. When the picking mechanism needs to pick up two or more materials at a time, the feeding section can be configured to hold multiple materials. The number of materials in the feeding section must be equal to or greater than the number of materials that the picking mechanism needs to pick up.

[0067] like Figures 1 to 4 As shown, specifically, the receiving channel 110 in this embodiment has a front loading section 111 and a rear loading section 112 at both ends, and the pushing cavity 120 is located between the front and rear loading sections. The front loading section 111 is closer to the feeding end 113 than the rear loading section 112. The front and rear loading sections are located outside the pushing cavity 120, and are divided into front and rear loading sections, which can increase the spacing between the parts. When the part size is small (e.g., IC chips), the spacing between the parts is small, and the size limit of the picking head of the picking mechanism cannot meet the requirement of multiple picking heads picking up adjacent parts. Therefore, by increasing the distance between the loading parts, multiple picking heads can pick up the parts. For example, if the chip size is a few millimeters, the length of two adjacent chips close together is less than the spacing between the two picking heads of the picking mechanism. Therefore, the picking head cannot pick up two chips at the same time. By loading with the front and rear loading sections, the parts can be picked up at intervals.

[0068] like Figure 1 , Figure 2 and Figure 5As shown, the receiving channel 110 has a feeding end 113 at one end and a closed end 114 at the other. The material enters through the feeding end 113 and moves towards the closed end 114, thus arranging itself within the receiving channel 110. The closed end 114 is closed, meaning the material cannot continue forward through it. The closed end 114 can be closed using structures such as fixed blocks. Those skilled in the art will understand that the closed end 114 does not necessarily have to be the end of the receiving channel 110. The closed end 114 can be a stopping end created by a detachable block or a retractable stop; it is sufficient that the material stops at the closed end 114. Several material pieces 10 sequentially enter the front loading section 111 through the feeding end 113 and pass through the pushing cavity 120 to the rear loading section 112, thereby forming a material belt 20 between the closed end 114 and the feeding end 113. After the picking mechanism takes away the material 10 from the material belt 20, the subsequent material entering the receiving channel 110 continues to push the remaining material forward and arrange it into a material belt, so that when the picking mechanism picks up the material, there are materials available at the loading position.

[0069] like Figure 5 As shown, further, the front loading section 111 is provided with a second fluid channel. The second fluid channel can adsorb or release the material 10 in the front loading section 111. The negative pressure generated by the second fluid channel can adsorb the material 10 in the receiving channel 110, making it unable to move. This positions the material belt between the closed end 114 and the adsorbed material, preventing the material from falling off when the receiving channel 110 moves. The second fluid channel can be designed to adsorb one or more material pieces, depending on the material handling method, the number of material pieces, etc. As one embodiment, the position of the second fluid channel corresponds to the last material piece in the front loading section 111, so that the first and last material pieces in the material belt 20 can be limited, preventing the material pieces in the material belt 20 from moving and falling off when the receiving channel 110 moves. Specifically, the receiving channel 110 receives the material 10 and forms the material belt 20, which includes material pieces T1 to T2. n There are n parts in total. Part T1 enters from the feed end and moves to the closed end 114. n It enters through the feed end, but cannot proceed further because the space ahead is already occupied by other materials. The second fluid channel allows material T to be moved... n Adsorption and positioning prevent the material from falling; furthermore, during material pickup by the picking mechanism, the second fluid channel provides positive pressure to break the vacuum, facilitating the pickup mechanism's picking up of the material. In other words, the second fluid channel can switch between negative pressure, no pressure, and positive pressure. Those skilled in the art will understand that if there are multiple materials outside the pushing chamber, the materials can also be... n and T n-1The number and structure of the second fluid channel are not limited here, and can be improved according to the actual structure of the receiving mechanism without departing from the overall concept of this embodiment.

[0070] like Figure 1 and Figure 2 As shown, furthermore, a first sensor 115 and a second sensor 116 are respectively provided at both ends of the receiving channel 110. The first sensor 115 detects the material at the feeding end 113 of the receiving channel 110, and the second sensor 116 detects the material at the closed end 114 of the receiving channel 110. The presence of material 10 at the corresponding position is determined by the first and second sensors. The first and second sensors are electrically connected to the control module. Existing sensors such as infrared sensors can be used. In this embodiment, a through-beam fiber optic sensor is used, that is, the first sensor includes a set of through-beam fiber optic sensors, and the second sensor includes a set of through-beam sensors. The through-beam fiber optic sensors are arranged opposite each other on both sides of the receiving channel 110. After component T1 enters the receiving channel 110 from the feeding end, the first sensor 115 detects its entry. The control module can preset the positive pressure activation of the first fluid channel after component T1 enters the receiving channel 110. For example, if two components enter the receiving channel 110, subsequent components will be unable to push the preceding component forward. Therefore, when the first sensor 115 detects two components entering, the control module activates the positive pressure of the first fluid channel. At this time, the first component T1 enters the pushing chamber 120 and can continue to move forward under positive pressure. When component T1 moves to the closed end 114, the second sensor 116 detects component T1. Until the last component Tn enters the receiving channel and cannot move forward, the first and second sensors continuously detect components, indicating that both ends of the component belt 20 have completed receiving.

[0071] The receiving principle of the receiving mechanism 100 in this embodiment will be further explained below, taking the simultaneous feeding of two material parts 10 as an example.

[0072] like Figures 1 to 5As shown, the receiving channel 110 has n consecutive material positions, each corresponding to one material, meaning the receiving channel 110 can accommodate n materials. The position closest to the infeed end 113 is the first material position, the position closest to the closed end 114 is the nth material position, and the second and (n-1)th material positions are located within the pushing cavity 120. This means that the materials 10 at the first and nth material positions can be simultaneously acquired. The materials 10 are transported one by one onto the receiving channel 110. When a material 10 is transported to the receiving channel 110, it has initial kinetic energy. After two materials 10 are loaded, the initial kinetic energy of subsequent materials cannot propel the preceding materials forward. The positive pressure airflow in the pushing cavity 120 assists in moving the materials forward until all n material positions are occupied. The materials then abut against each other to form a material belt 20, thus completing one receiving cycle. At this time, the two picking heads of the picking mechanism can simultaneously pick up parts 10 at the first and nth parts positions. After removing two parts, the material belt 20 becomes empty. It continues to pick up materials, allowing subsequent parts to move forward, filling the empty spaces, and filling all parts positions again. The picking mechanism can then continue picking up materials at the first and nth parts positions. Those skilled in the art will understand that the number of parts in the material belt 20 and the selection of which parts to pick up can be improved according to the picking mechanism and picking requirements, without departing from the concept of this embodiment.

[0073] <Example 2>

[0074] In this embodiment, the parts that are the same as in Embodiment 1 are given the same reference numerals, and the same text descriptions are omitted.

[0075] like Figure 7 As shown, compared to Embodiment 1, the receiving mechanism provided in this embodiment has the following structural design differences:

[0076] The receiving mechanism of this embodiment is used to simultaneously feed three parts. The pushing cavity 120' of this embodiment is provided with a through hole 121' communicating with the receiving channel 110. The through hole 121' is located above the receiving channel 110. The size and shape of the through hole 121' can be designed according to the type of part and the structure of the picking mechanism. The part 10 moves along the receiving channel 110 and can pass through the through hole 121'. The picking mechanism can pick up the part through the through hole 121'. Because 121' is located between the front feeding part and the rear feeding part, the picking mechanism can simultaneously pick up the parts 10 at the front, middle and rear positions.

[0077] Understandably, if four parts need to be taken at the same time, it can be done by setting two through holes 121'.

[0078] This embodiment enables the simultaneous picking of three or more materials, further improving the efficiency of material picking.

[0079] <Example 3>

[0080] In this embodiment, the parts that are the same as in Embodiments 1 and 2 are given the same reference numerals, and the same text descriptions are omitted.

[0081] like Figure 1 , Figures 8 to 14 As shown, compared to the above embodiments, the receiving mechanism provided in this embodiment has the following structural design:

[0082] In this embodiment, the receiving channel 110 is disposed on the receiving fixture 130. Specifically, the receiving channel 110 is a straight groove opened on the receiving fixture 130, and the material moves in a straight line within the straight groove. The receiving fixture 130 is provided with a cover plate 140, which covers the receiving channel 110, thereby partially covering the receiving channel 110, while the feeding positions at both ends of the receiving channel 110 are exposed for easy feeding. The pushing cavity 120 is located between the cover plate 140 and the receiving fixture 130. The pushing cavity 120 can be formed by the close fitting assembly of the cover plate 140 and the receiving fixture 130, which facilitates processing and assembly. The cover plate 140 has a guide groove 141, which is located above the receiving channel 110 and extends a certain length along the extending direction of the receiving channel 110 (i.e., the feeding direction X). The size and position of the guide groove 141 correspond to the receiving channel 110. The receiving channel 110 and the guide groove 141 form a chamber, thereby allowing the material 10 to move smoothly. At the same time, airflow can enter the receiving channel 110 through the guide groove 141 to assist the movement of the material. The guide groove 141 is provided with an exhaust hole 144, through which airflow can be discharged to avoid excessive pressure in the pushing chamber 120 due to the inability of positive pressure airflow to escape.

[0083] like Figure 2 As shown, the first fluid channel further includes a left air duct 150A and a right air duct 150B respectively disposed on both sides of the receiving channel 110. Specifically, the left and right air ducts are air grooves formed on the cover plate 140 and are symmetrically arranged about the guide groove 141. The left and right air ducts are connected to the receiving channel 110 through air outlets 151. The airflow is output through the air outlets 151. By blowing air through both sides of the receiving channel 110, the movement of the material 10 in the receiving channel 110 can be made smoother. Multiple air outlets 151 can be provided on each side of the receiving channel 110. The multiple air outlets 151 are arranged at intervals along the extension direction of the receiving channel 110, so that the airflow is output at multiple positions, providing auxiliary thrust to the material 10 at different positions.

[0084] like Figure 2 , Figure 4 , Figures 8 to 9As shown, the left air passage 150A and the right air passage 150B are respectively connected to the first inlet 142 and the second inlet 143 of the cover plate 140. The first and second inlets correspond to the first outlet 131 and the second outlet 132 on the front of the receiving fixture 130, respectively. The first and second outlets are connected through the slot 133 on the back of the receiving fixture 130, so that the first and second outlets can be connected in series through the slot 133. The airflow entering the slot 133 can be supplied to the first and second outlets respectively, and then supplied to the left and right air passages respectively.

[0085] like Figure 3 , Figures 7 to 12 As shown, the receiving fixture 130 is mounted on the base 160, facilitating the processing of the first and second fluid channels. The base 160 has a first air hole 161 and a first air outlet 162 communicating with the first air hole 161. The first air hole 161 is connected to an air source, and the first air outlet 162 is connected to the slot 133. The airflow of the first fluid channel enters through the first air hole 161 on the side of the base and exits through the first air outlet 162 on the front of the base, thereby changing the airflow direction. Accessories such as air pipe connectors can be installed on the first air hole 161 to facilitate pipe connection. The receiving fixture 130 is positioned in the mounting slot 163 of the base 160. After installation, the slot 133 corresponds to the first air outlet 162, allowing the airflow from the first air outlet 162 to enter the slot 133 and then enter the receiving channel 110 through the left and right air passages, thus dispersing one intake airflow into two airflows entering the receiving channel 110.

[0086] like Figure 4 , Figures 8 to 13 As shown, the receiving channel 110 is further connected to the second fluid channel. The second fluid channel includes a connecting port 171 located on the front of the receiving fixture. The connecting port 171 is connected to a guide groove 134 on the back of the receiving fixture 130. The guide groove 134 is a strip-shaped groove of a certain length, which can change the airflow path. The receiving fixture 130 is mounted on the base 160. The base 160 has a second air hole 164 and a second air outlet 165 connected to the second air hole 164. The second air outlet 165 is located on the front of the base 160 and is connected to an air source. The second air hole 164 is located on the side of the base 160, and the guide groove 134 is connected to the second air outlet 165. When the receiving fixture 130 is mounted on the base 160, the second air outlet 165 is connected to the guide groove 134, and the airflow of the second fluid channel enters and exits through the second air hole 164.

[0087] The first fluid channel and the second fluid channel are interconnected through multiple holes of various types on the base 160, the receiving fixture 130 and the cover plate 140, which can ensure air passage connection while maintaining the compact structure of the base 160, the receiving fixture 130 and the cover plate 140.

[0088] like Figure 14 As shown, as an example, the pressure control of the first and second fluid channels can be achieved through solenoid valves, which, in conjunction with the control module, control the movement of the material receiving mechanism. A first air vent 161 and a second air vent 164 are provided on the side of the base 160. The second air vent 164 is controlled by a two-position four-way solenoid valve and a two-position two-way solenoid valve, enabling switching between positive / negative pressure, negative pressure, and no pressure states. The two-position two-way solenoid valve controls the overall on / off flow of gas into the base 160, while the two-position four-way solenoid valve switches between positive and negative pressure states. The three states can be switched through the combined use of these two solenoid valves. The first fluid channel can be controlled by a two-position two-way solenoid valve to open and close the air passage.

[0089] <Example 4>

[0090] In this embodiment, the parts that are the same as in Embodiments 1, 2 and 3 are given the same reference numerals, and the same text descriptions are omitted.

[0091] like Figures 15 to 17 As shown, compared to the above embodiments, the receiving mechanism provided in this embodiment has the following structural design differences:

[0092] In this embodiment, the receiving channel 110 of the receiving mechanism is disposed in the driving component 180. The driving component 180 can drive the receiving channel 110 to move, so that the material belt on the receiving channel 110 can move quickly to the required position as a whole, realizing rapid feeding. In this embodiment, the driving component 110 can reciprocate between the receiving position and the feeding position. When the receiving channel 110 is in the receiving position, the material enters the receiving channel; when the receiving channel is in the feeding position, the picking mechanism picks up the material. The specific structure of the driving component 180 can be implemented by a cylinder, belt drive, cam mechanism, or other driving mechanism. Those skilled in the art can realize structural transformation to achieve the movement of the receiving channel without creative effort.

[0093] like Figure 15 and Figure 16As shown, further, as an example, the drive assembly 180 includes a transplanting seat 181, a cam assembly 182, and a servo motor 183. The servo motor 183 is connected to the transplanting seat 181 via the cam assembly 182, and the receiving channel 110 is disposed on the transplanting seat 181. Through the transmission via the cam assembly 182, the overall structure of the drive assembly is compact, occupies little space, and exhibits smooth and high-precision movement. The cam assembly 182 includes a motor clamping block 1821, a cam follower 1822, and a cam slider 1823. The motor clamping block 1821 is disposed on the motor shaft of the servo motor 183. The cam follower 1822 is eccentrically disposed on the motor clamping block 1821 and located within the receiving groove 1824 of the cam slider 1823. The cam slider 1823 is connected to the transplanting seat 181. The rotation of the motor shaft of the servo motor 183 drives the motor clamping block 1821 to rotate, which in turn drives the cam follower 1822 to rotate. Because the cam follower 1822 is eccentrically positioned relative to the motor shaft, it can generate cam motion, causing the cam slider 1823 to oscillate. The transplanting seat 181 is further mounted on the slide rail 186 for smoother movement. Furthermore, a limiting block 184 is provided on the side of the transplanting seat 181.

[0094] Furthermore, the drive assembly 180 is connected to the horizontal adjustment assembly 190 and the lifting adjustment assembly 200. The horizontal adjustment assembly 190 pushes the drive assembly 180 to move horizontally, specifically along the Y direction in the figure. The Y direction is perpendicular to the material movement direction in the receiving channel, allowing the receiving channel 110 to be finely adjusted left and right. The lifting adjustment assembly 200 pushes the drive assembly 180 vertically, specifically along the Z direction in the figure. The receiving channel 110 moves synchronously with the drive assembly 180, thereby allowing the height of the receiving channel to be adjusted according to different picking mechanisms. Through the above technical solution, the applicability of the receiving mechanism to different materials, picking mechanisms, and feeding needs can be further improved, expanding the application range.

[0095] Furthermore, the horizontal adjustment assembly 190 includes an adjustment block 191, which has a horizontal adjustment element 192. The horizontal adjustment element 192 is correspondingly disposed with the support plate 185 of the drive assembly 180. The horizontal adjustment element 192 pushes the support plate 185 to move. The horizontal adjustment element 192 can be a screw, pin, etc. In this embodiment, a screw is used. The screw is threadedly connected to the adjustment block 191 and faces the support plate 185. The support plate 185 is pushed by rotating the screw. The horizontal adjustment assembly 190 is disposed on both sides of the support plate 185, so it can be adjusted from both sides. The lifting adjustment assembly 200 includes a mounting plate 201. The support plate 185 is disposed on the mounting plate 201. The mounting plate 201 is provided with a lifting adjustment element 202. One end of the lifting adjustment element 202 is provided with an eccentric shaft 203 connected to the mounting plate 201. Rotating the lifting adjustment element 202 drives the mounting plate 201 to rise or fall. The lifting adjustment component 202 is a shaft-shaped component mounted on the base plate 204. Rotating the lifting adjustment component 202 drives the eccentric shaft 203 to rotate, and the eccentric shaft 203 swings vertically, thereby causing the mounting plate 201 to rise or fall. This method allows users to easily adjust the height of the receiving channel 110.

[0096] <Example 5>

[0097] In this embodiment, the parts that are the same as in embodiments one to four are given the same reference numerals, and the same text descriptions are omitted.

[0098] like Figures 1 to 6 and Figure 18 As shown, compared to the aforementioned embodiments, this embodiment provides a receiving method for receiving and organizing small, lightweight components such as chips and electronic components. The receiving method of this embodiment can be implemented using the receiving mechanism of the aforementioned embodiments, and includes the following steps:

[0099] S100: Several parts 10 are received sequentially through the receiving channel 110. The parts enter through the feed end 113 at one end of the receiving channel 110 and move towards the closed end 114. The parts 10 enter the receiving channel one by one until n parts fill the receiving channel 110, forming a material belt of n parts.

[0100] S200: When component 10 enters the pushing chamber 120, it is propelled by the airflow from the first fluid channel and moves along the conveying direction X of the receiving channel. After entering the receiving channel 110, component 10 first slides within the receiving channel 110 using its own kinetic energy and enters the pushing chamber 120. Due to the frictional resistance of the receiving channel, component 10 gradually decelerates. Components entering the receiving channel 110 later collide and push with components in front. As the number of components in front increases, the kinetic energy of the components in rear is insufficient to push the components in front, causing them to be unable to move forward. Therefore, after component 10 enters the pushing chamber 120, a positive pressure airflow is supplied to the pushing chamber through the first fluid channel, propelling component 10 to continue moving forward and preventing it from losing power and becoming stuck in the receiving channel.

[0101] S300: The components are arranged sequentially in the receiving channel until the receiving channel 110 is full, forming a component belt. The components in the receiving channel 110 are arranged in a straight line. The first component T1 is blocked and stopped by the closed end 114. The second component T2 is blocked and stopped by the first component. After the last component Tn enters the receiving channel 110, there is no space to move forward, and there is no space behind for the next component to enter the receiving channel. At this time, the components fill the receiving channel. At this time, components T1 to Tn are arranged in a straight line between the feeding end 113 and the closed end 114, forming a component belt 20.

[0102] The above-mentioned material receiving method enables the materials to move smoothly and be arranged neatly in sequence after entering the material receiving channel, which facilitates the subsequent picking mechanism to pick up the materials; at the same time, forming a material belt also facilitates the overall movement of multiple materials.

[0103] In step S100, the material 10 enters through the feed end 113 of the receiving channel 110 and is arranged sequentially from the closed end 114 of the receiving channel 110 toward the feed end to form a material belt 20. When the material in the material belt 20 is removed, the material 10 continues to enter the receiving channel 110 from the feed end 113 until the empty position of the material belt 20 where the material was removed is refilled with material, thereby ensuring that the material can be quickly replenished after it is continuously removed.

[0104] Following step S300, the receiving channel 110 further moves between the receiving position and the loading position. Before moving, the receiving channel 110 uses a second fluid channel to provide negative pressure to position the material on the material belt 20. The receiving position is where the receiving channel 110 receives the material; at this position, the material can be supplied by a feeding mechanism such as a vibratory feeder. The loading position is where the receiving channel 110 supplies material; a robotic arm, nozzle, gripper, or other picking mechanism picks up the material from the receiving channel 110 at the loading position. The movement of the receiving channel 110 allows for rapid switching between different positions; the negative pressure provided by the second fluid channel to position the material prevents it from falling out of the receiving channel during movement. The second fluid channel is connected to an air source.

[0105] Furthermore, the feeding end 113 and the closed end 114 of the receiving channel 110 are respectively equipped with a first sensor 115 and a second sensor 116. When the first sensor 115 detects a material, airflow is output through the first fluid channel; when the first sensor 115 and the second sensor 116 simultaneously detect a material, the second fluid channel switches from a pressureless state to a negative pressure state, and the receiving channel 110 moves from the receiving position to the feeding position. During feeding, the second fluid channel of the receiving channel 110 is in a pressureless state, that is, no negative or positive pressure is formed, so the material is not subject to the suction force of the second fluid channel, which facilitates its movement. When the last material Tn enters the receiving channel, the second fluid channel switches to a negative pressure state, and the resulting suction force holds the material. Optionally, the second fluid channel can adsorb at least one or more materials. Preferably, when the receiving channel limits the two sides of the material, it adsorbs the last material, so that the two sides and the beginning and end of the material belt can be limited, thereby preventing the material from falling off. At the same time, compared with adsorbing multiple materials, a simpler structure can be used to achieve this. When the receiving channel moves to the loading position, the second fluid channel switches to positive pressure, making it easier for the material to be removed.

[0106] The feeding method in this embodiment adopts a piece-by-piece feeding method with airflow assistance, which can prevent the material from stagnating after entering the receiving channel, and allow several materials to be arranged sequentially in the receiving channel to form a material belt for easy retrieval. At the same time, the material belt can move as a whole, which is convenient for moving between the receiving position and the feeding position; the second fluid channel can position and release the materials to prevent them from falling during the movement.

[0107] Example 6

[0108] In this embodiment, the parts that are the same as in embodiments one to five are given the same reference numerals, and the same text descriptions are omitted.

[0109] like Figures 1 to 6 and Figure 19 As shown, compared to the previous embodiment, this embodiment provides a feeding device for supplying small, lightweight components such as chips and electronic components. The feeding device includes the aforementioned receiving mechanism 100 and a feeding mechanism 300 disposed on one side of the receiving mechanism 100. The feeding mechanism 300 is used to convey the component 10 to the receiving mechanism 100. The feeding mechanism 300 can be an existing feeding mechanism such as a disc feeder or a tubular feeder. In this embodiment, the feeding mechanism 300 includes a vibrating bowl base 310 and a vibrating bowl 320 disposed on the vibrating bowl base 310. The vibrating bowl 320 vibrates, causing the component to enter the feeding channel 330 and move towards the receiving mechanism and be fed into the receiving channel 110 of the receiving mechanism 100.

[0110] like Figure 19As shown, the receiving channel 110 is further spaced apart from the feeding channel 330 of the feeding mechanism 300. The receiving channel 110 moves closer to or further away from the feeding mechanism 300 via the drive assembly 180. The separation of the receiving channel 110 and the feeding channel 330 prevents the feeding channel 330 from transmitting vibrations to the receiving channel when the feeding mechanism 300 vibrates, thus avoiding vibrations that could affect the feeding accuracy. When the receiving channel 110 is in the feeding position, the material in the feeding channel 330 passes through the gap between the receiving channel and the feeding channel and enters the receiving channel through the feed end. After the receiving channel 110 is full, it moves to the feeding position below the picking mechanism 400, and the picking mechanism 400 descends to pick up the material. In this embodiment, the picking mechanism 400 uses several suction nozzles to pick up the material.

[0111] In the above embodiments one to six, during the working process, depending on the different working environments, some of the technical implementation methods of embodiments one to six can be combined or replaced.

[0112] The technical principles of the present invention have been described above in conjunction with specific embodiments. However, it should be noted that these descriptions are merely for explaining the principles of the present invention and should not be construed as limiting the scope of protection of the present invention in any way. Based on this explanation, those skilled in the art can conceive of other specific embodiments or equivalent substitutions of the present invention without creative effort, and all such embodiments will fall within the scope of protection of the present invention.
