Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of automation equipment, in particular to a feeding device. BACKGROUND

[0002] Many products need to be installed with bolts for fastening. In order to improve production efficiency, automatic feeding of bolts has become a common processing technology. Through the automatic equipment, the bolts are installed in the designated position, thereby reducing the amount of manual work and improving the accuracy and efficiency of bolt installation. However, there are many types of bolts on each product and different models, so different dedicated feeding devices need to be provided for each type of bolt.

[0003] In the related art, before the next type of bolt needs to be installed, the automatic feeding device corresponding to the current type of bolt needs to be removed from the production line as a whole, and then the automatic feeding device corresponding to the next type of bolt needs to be moved into the production line. Finally, the new device is used to feed and install the new type of bolt. However, there are many types of bolts, and the operation of moving in and out of different devices is complicated and time-consuming, which can easily cause the production line to stop for a long time, reduce the efficiency of bolt feeding, and thus reduce the processing efficiency of the production line.

Then, the clamping component of the feeding device can clamp the material to be dispensed and release it to the designated position to complete the dispensing process. Since each switching block has a material channel corresponding to a different material to be dispensed, the switching cylinder can drive the switching block to move to switch the material channel corresponding to the guide tube.

Detailed Implementation

[0050] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0051] Unless otherwise defined, all technical terms used in the embodiments of this application have the same meaning as commonly understood by those skilled in the art.

[0052] To make the technical solutions and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0053] Combination Figure 1 and Figure 2 As shown in the figure, this application embodiment provides a dispensing device, which includes a material dispensing device 100, an air blowing device 200, and a material feeding device 300.

[0054] The material dispensing device 100 includes a switching cylinder 110 and a switching block 120. The switching cylinder 110 is connected to the switching block 120. The switching block 120 includes an adjacent first surface 121 and a second surface 122. The switching block 120 is provided with at least two material channels 123. The size of the material channels 123 corresponds one-to-one with the size of the material to be fed 400. The first end of the material channel 123 is exposed on the first surface 121, and the second end of the material channel 123 is exposed on the second surface 122. It should be noted that the material to be fed 400 can be, for example, a bolt or other part.

[0055] The air blowing device 200 includes an air supply component 210 and a conduit 220. A first end of the conduit 220 is connected to the air outlet of the air supply component 210 and a second end of any material channel 123. A switching cylinder 110 drives a switching block 120 to move, thereby switching the material channel 123 connected to the conduit 220. It should be noted that the air supply component 210 can be, for example, an air pump.

[0056] The feeding device 300 includes a limiting member 310 and a clamping assembly 320. The limiting member 310 is connected to the second end of the conduit 220 and has a first limiting hole 311 communicating with the second end of the conduit 220. The clamping assembly 320 is used to clamp and release the material 400 to be fed from the conduit 220 into the first limiting hole 311. With this configuration, the material 400 to be fed can fall into the conduit 220 of the feeding device 300 through the second end of the material channel 123 and be blown into the first limiting hole 311 of the feeding device 300 by the air supply member 210. Then, the clamping assembly 320 places the material 400 into a designated position, such as into a mounting hole on a component to be installed, thereby completing the feeding process of the material 400.

[0057] Since each switching block 120 has a material channel 123 corresponding to different materials 400 to be fed, the switching block 120 can be moved by the switching cylinder 110 to switch the material channel 123 corresponding to the conduit 220. In this way, when the production line needs to feed different types of materials 400, the switching block 120 can be moved into place by the switching cylinder 110, and the materials 400 to be fed can be fed from the corresponding material channel 123 into the conduit 220, and then fed to the designated position, without having to move the entire feeding device out of or into the production line. This improves the efficiency of feeding materials 400 of different sizes, and thus improves the processing efficiency of the production line.

[0058] The following is in conjunction with the appendix Figures 1 to 9 The various components and functions of the delivery device provided in the embodiments of this application will be described in more detail.

[0059] like Figure 3 As shown, in some embodiments, the material distribution device 100 further includes a feeding component 130, which abuts against the first surface 121. The feeding component 130 has a first through groove 131, the first end of which communicates with the first end of the material channel 123, and the second end of which is adapted to communicate with the outlet of the vibrator. It should be noted that multiple materials 400 to be fed can be fed one by one from the vibrator into the first through groove 131, and the multiple materials 400 to be fed are arranged sequentially according to the extending direction of the first through groove 131. The width and height of the first through groove 131 are matched with the width and height of the corresponding materials 400 to be fed, thereby ensuring that materials 400 of different sizes can enter the corresponding material channel 123 from the first through groove 131 respectively. It should be noted that the position of the feeding component 130 is fixed. For example, it can be installed and fixed on the ground by a support frame. When the switching cylinder 110 drives the switching block 120 to move, the switching block 120 can move relative to the feeding component 130 until the first end of the first channel 131 is connected to the first end of the corresponding material channel 123.

[0060] Combination Figure 3 and Figure 8 As shown, in some embodiments, the material to be fed 400 is located within the first channel 131. The material to be fed 400 includes a rod-shaped portion 410 and an annular portion 420, with the annular portion 420 sleeved on the rod-shaped portion 410. The top of the first channel 131 abuts against the side of the annular portion 420 facing the bottom of the first channel 131, and the bottom end of the rod-shaped portion 410 abuts against the bottom of the first channel 131. This prevents the material to be fed 400 from tilting, thereby allowing the material to be fed 400 to be aligned with the first end of the material channel 123 and enter the material channel 123.

[0061] like Figure 2 As shown, in some embodiments, the material distribution device 100 further includes a vibrator 170, which is installed at the bottom of the feeding component 130. It should be noted that when the vibrator 170 vibrates, it can drive the material to be fed 400 in the feeding component 130 to move sequentially into the corresponding material channel 123.

[0062] Combination Figure 2 and Figure 3 As shown, in some embodiments, the dispensing device further includes a fixed support 500, which includes a first sidewall 510, a base 520, and a second sidewall 530 connected to each other, with the first sidewall 510 and the second sidewall 530 disposed opposite to each other. A switching block 120 is movably mounted on the base 520. A switching cylinder 110 includes a first drive member 111 and a first telescopic rod 112. The first drive member 111 is mounted on the first sidewall 510, and the first telescopic rod 112 passes through the first sidewall 510 and is connected to the switching block 120. The first drive member 111 drives the first telescopic rod 112 to extend or retract along a first direction, wherein the first direction is parallel to the direction from the first sidewall 510 to the second sidewall 530. It is understood that when the first drive member 111 drives the first telescopic rod 112 to extend, the first telescopic rod 112 can push the switching block 120 toward the second sidewall 530. When the first driving member 111 drives the first telescopic rod 112 to shorten, the first telescopic rod 112 can drive the switching block 120 to move toward the first side wall 510. In this way, by using the first telescopic rod 112 to drive the switching block 120 to move, the material channel 123 on the switching block 120 that communicates with the conduit 220 can be adjusted, so that materials 400 of different sizes can be put into the conduit 220 through the corresponding material channel 123.

[0063] like Figure 4 As shown, in some embodiments, the base 520 is provided with an opening 521, and the second end of the material channel 123, the opening 521 of the base 520, and the first end of the conduit 220 are sequentially connected. It should be noted that the first end of the conduit 220 is connected to the opening 521 and the air outlet of the air supply component 210 respectively through a connecting pipe 800.

[0064] like Figure 4 As shown, in some embodiments, the dispensing device 100 further includes a first guide bar 140, which is located on the base 520 and extends along a first direction. The second surface 122 of the switching block 120 has a first slot 124, and at least a portion of the first guide bar 140 is engaged in the first slot 124. It should be noted that the first guide bar 140 can guide the movement of the switching block 120, ensuring that the switching block 120 can move smoothly along the first direction and avoid deviation, thereby ensuring that the second end of the material channel 123 in the switching block 120 can be aligned with the first end of the conduit 220, ensuring that the material to be fed 400 is smoothly fed into the conduit 220.

[0065] Combination Figures 2 to 4 As shown, in some embodiments, the switching block 120 further includes a third surface 125 and a fourth surface 126 disposed opposite to each other, the third surface 125 facing the first sidewall 510 and the fourth surface 126 facing the second sidewall 530. The dispensing device 100 also includes a first limiting component 150 and a second limiting component 160, one end of the first limiting component 150 passing through the first sidewall 510 and extending along a first direction, and one end of the second limiting component 160 passing through the second sidewall 530 and extending along the first direction. The switching block 120 is located between the first limiting component 150 and the second limiting component 160, and the switching cylinder 110 drives the switching block 120 to move so that the third surface 125 abuts against the end of the first limiting component 150, or so that the fourth surface 126 abuts against the end of the second limiting component 160. Understandably, when the switching block 120 moves toward the first sidewall 510, the first limiting component 150 can limit the movement position of the switching block 120; when the switching block 120 moves toward the second sidewall 530, the second limiting component 160 can limit the movement position of the switching block 120. This prevents the switching block 120 from moving excessively, thereby ensuring that the second end of the material channel 123 within the switching block 120 can be aligned with the guide tube 220.

[0066] like Figure 3As shown, in some embodiments, the first limiting component 150 includes a first support member 151 and a first elastic member 152 arranged side by side. The first end of the first support member 151 is connected to the first sidewall 510, and the second end extends toward the second sidewall 530. The first end of the first elastic member 152 is connected to the first sidewall 510, and the second end is elastic and extends toward the second sidewall 530. The distance between the second end of the first elastic member 152 and the second sidewall 530 is less than the distance between the second end of the first support member 151 and the second sidewall 530. It should be noted that when the switching block 120 moves toward the first sidewall 510, the end of the first elastic member 152 can first collide with the third surface 125 of the switching block 120, thereby buffering the switching block 120. Then, the second end of both the first elastic member 152 and the second end of the first support member 151 abut against the third surface 125 of the switching block 120 to limit the movement position of the switching block 120. It should be noted that the first end of the first elastic member 152 and the first end of the first support member 151 can pass through the corresponding mounting holes on the first side wall 510, respectively.

[0067] like Figure 3 As shown, in some embodiments, the second limiting component 160 includes a second support member 161 and a second elastic member 162 arranged side by side. The first end of the second support member 161 is connected to the second sidewall 530, and the second end extends toward the first sidewall 510. The first end of the second elastic member 162 is connected to the second sidewall 530, and the second end is elastic and extends toward the first sidewall 510. The distance between the second end of the second elastic member 162 and the first sidewall 510 is less than the distance between the second end of the second support member 161 and the first sidewall 510. It should be noted that when the switching block 120 moves toward the second sidewall 530, the end of the second elastic member 162 can first collide with the fourth surface 126 of the switching block 120, thereby buffering the switching block 120. Then, the second end of the second elastic member 162 and the second end of the second support member 161 both abut against the fourth surface 126 of the switching block 120, thus limiting the movement position of the switching block 120. It should be noted that the second end of the second elastic member 162 and the second end of the second support member 161 can pass through the corresponding mounting holes on the second side wall 530, respectively.

[0068] Combination Figure 5 and Figure 6As shown, in some embodiments, the feeding device 300 further includes a fixed base 330, one end of which is connected to a limiting member 310, and the other end is adapted to be connected to a robotic arm. A clamping assembly 320 is mounted on the fixed base 330. Since the fixed base 330 is connected to the robotic arm, when the clamping assembly 320 clamps the material to be fed 400, the robotic arm can drive the fixed base 330 to move, and thus the clamping assembly 320 can move synchronously with the fixed base 330. This allows for adjustment of the position where the clamping assembly 320 releases the material to be fed 400, improving the flexibility and accuracy of feeding the material to be fed 400. In some embodiments, the fixed base 330 and the robotic arm can be connected via a fixed plate 900, which is connected to a second fixed block 332.

[0069] Combination Figure 5 and Figure 6 As shown, in some embodiments, the fixing base 330 includes a first fixing block 331 and a second fixing block 332. The first fixing block 331 is mounted on the second fixing block 332, and the first fixing block 331 is connected to the limiting member 310 and the robotic arm respectively.

[0070] The clamping assembly 320 includes a clamping cylinder 321 and a clamping cylinder 322. The clamping cylinder 321 includes a second driving member 3211 and a locking assembly 3212. The second driving member 3211 is mounted on the second fixing block 332 and is used to drive the locking assembly 3212 to switch between a locked state and a disengaged state.

[0071] The clamping cylinder 322 includes a third driving member 3221 and a clamping assembly 3222. The third driving member 3221 is mounted on the second fixing block 332. The third driving member 3221 is used to drive the clamping assembly 3222 to switch between a clamping state and a releasing state. The locking assembly 3212 is located between the limiting member 310 and the clamping assembly 3222.

[0072] When the locking component 3212 is in the locked state, it holds the material 400 that has fallen from the first limiting hole 311. When the locking component 3212 is in the disengaged state, the clamping component 3222 is in the clamping state to clamp and release the material 400. It can be understood that the first fixing block 331 and the second fixing block 332 can integrate the limiting member 310, the clamping cylinder 321 and the clamping cylinder 322 into one unit. Thus, when the robotic arm moves the first fixing block 331, the limiting member 310, the clamping cylinder 321 and the clamping cylinder 322 can move synchronously with the robotic arm, thereby flexibly adjusting the release position of the material 400. It should be noted that when the material to be fed 400 falls from the second end of the conduit 220, the locking component 3212 of the clamping cylinder 321 can buffer the material to be fed 400. When the material to be fed 400 is stable, the locking component 3212 is in a disengaged state, and the clamping component 3222 can clamp the material to be fed 400 released by the locking component 3212. Then the clamping component 3222 can clamp the material to be fed 400 to the designated position and then release it.

[0073] like Figure 6 As shown, in some embodiments, the second fixing block 332 has a first through hole 3321, and the limiting member 310 passes through the first through hole 3321 to fix the limiting member 310.

[0074] like Figure 6 As shown, in some embodiments, the locking assembly 3212 includes a first locking arm 3213 and a second locking arm 3214. A second driving member 3211 is used to drive the first locking arm 3213 and the second locking arm 3214 to move towards each other or away from each other. The first locking arm 3213 is provided with a second slot 3215, and the second locking arm 3214 is provided with a third slot (not shown in the figure). The second slot 3215 and the third slot are arranged opposite to each other in the moving direction of the first locking arm 3213.

[0075] The feeding device 300 also includes a second guide bar 340, which is mounted on the second fixed block 332. The second guide bar 340 extends along the moving direction of the first locking arm 3213, and at least a portion of the second guide bar 340 is respectively engaged in the second slot 3215 and the third slot. It should be noted that the second guide bar 340 can guide the movement of the first locking arm 3213 and the second locking arm 3214, ensuring that the first locking arm 3213 and the second locking arm 3214 move in the same direction, thereby preventing misalignment of the first locking arm 3213 and the second locking arm 3214, that is, ensuring that the first locking arm 3213 and the second locking arm 3214 can always be aligned, so that the locking assembly 3212 can stably clamp the material to be fed 400.

[0076] CombinationFigure 6 and Figure 7 As shown, in some embodiments, when the first locking arm 3213 abuts against the second locking arm 3214, a limiting channel 350 is formed. The limiting channel 350 includes a second limiting hole 351 and a third limiting hole 352 that are connected. The first limiting hole 311, the second limiting hole 351, and the third limiting hole 352 are connected sequentially. The inner diameter of the second limiting hole 351 is the same as the inner diameter of the first limiting hole 311. The inner diameter of the third limiting hole 352 gradually decreases from the first limiting hole 311 towards the third limiting hole 352. Since the inner diameter of the third limiting hole 352 gradually decreases, it is equivalent to a trumpet shape. Therefore, when the material to be fed 400 falls into the limiting channel 350 from the first limiting hole 311, the wall of the third limiting hole 352 can buffer the material to be fed 400.

[0077] Combination Figure 6 , Figure 7 and Figure 8 As shown, in some embodiments, the inner diameter of the end of the third limiting hole 352 near the first limiting hole 311 is not less than the outer diameter of the annular portion 420 of the material to be fed 400, and the inner diameter of the end of the third limiting hole 352 away from the first limiting hole 311 is less than the outer diameter of the annular portion 420 but greater than the outer diameter of the rod-shaped portion 410. Therefore, when the material to be fed 400 falls into the limiting channel 350 from the first limiting hole 311, the limiting channel 350 not only acts as a buffer for the material to be fed 400, but also allows the rod-shaped portion 410 exposed from the third limiting hole 352 to be clamped by the clamping component 3222, thus enabling the clamping component 3222 to clamp the material to be fed 400. Furthermore, it prevents the material to be fed 400 from detaching from the locking component 3212, thereby preventing the material to be fed 400 from falling directly and failing to be clamped by the clamping component 3222 when the clamping component 3222 is not in a clamping state.

[0078] like Figure 6 As shown, in some embodiments, the dispensing device further includes a material detection sensor 600, which is mounted on the first fixing block 331. The material detection sensor 600 is used to detect whether the material to be dispensed 400 has fallen into the locking assembly 3212. It should be noted that by using the material detection sensor 600, it is possible to ensure that the locking assembly 3212 is switched to the disengaged state only after the material to be dispensed 400 has fallen into the locking assembly 3212, so that the clamping assembly 3222 can clamp the material to be dispensed 400, avoiding the clamping assembly 3222 from emptying the clamp and improving the effectiveness of the clamping operation.

[0079] like Figure 6As shown, in some embodiments, the material detection sensor 600 includes a transmitter 610 and a receiver 620, which are located on opposite sides of the locking assembly 3212 and connected to the first fixing block 331. The first locking arm 3213 has a second through hole 3217, and the second locking arm 3214 has a third through hole (not shown in the figure), with the second through hole 3217 communicating with the third through hole. The transmitter 610 emits an infrared beam that passes sequentially through the second through hole 3217 and the third through hole, and the receiver 620 receives the infrared beam emitted by the transmitter 610. It should be noted that when the receiver 620 receives the infrared beam, it indicates that the material to be fed 400 has not yet fallen into the limiting channel 350; when the receiver 620 does not receive the infrared beam, it indicates that the material to be fed 400 has fallen into the limiting channel 350. This ensures that the subsequent third drive component 3221 drives the clamping component 3222, thereby ensuring the effectiveness of the clamping component 3222 in clamping the material to be fed 400.

[0080] like Figure 6 As shown, in some embodiments, the clamping assembly 3222 includes a first clamping arm 3223 and a second clamping arm 3224. The first clamping arm 3223 and the second clamping arm 3224 are respectively connected to a third driving member 3221. The third driving member 3221 can drive the first clamping arm 3223 and the second clamping arm 3224 to extend and retract in a direction perpendicular to the moving direction of the first locking arm 3213, and the third driving member 3221 can drive the first clamping arm 3223 and the second clamping arm 3224 to move closer to each other or further away from each other in a direction parallel to the moving direction of the first locking arm 3213. Thus, after the locking assembly 3212 locks the material to be fed 400, the third driving member 3221 can drive the first clamping arm 3223 and the second clamping arm 3224 to move to the position corresponding to the limiting channel 350 and clamp the part of the rod-shaped portion 410 exposed from the third limiting hole 352, thereby feeding the material to be fed 400 to the designated position.

[0081] like Figure 6 As shown, in some embodiments, the clamping ends of the first clamping arm 3223 and the second clamping arm 3224 form a V-shape. This increases the clamping force on the material to be fed 400 and improves the stability of the clamping.

[0082] like Figure 6As shown, in some embodiments, the feeding device 300 further includes a positioning member 360, which is connected to the second fixing block 332. The positioning member 360 has a fourth slot 361, which is coaxial with the third limiting hole 352. The fourth slot 361 is in clearance fit with the rod-shaped portion 410 of the material to be fed 400. The clamping assembly 3222 is located between the positioning member 360 and the locking assembly 3212. It should be noted that after the material to be fed 400 falls into the limiting channel 350, part of the rod-shaped portion 410 protrudes from the third limiting hole 352 and extends into the fourth slot 361. In this way, the positioning member 360 can position the material to be fed 400 so that the clamping assembly 3222 can clamp the material to be fed 400.

[0083] Combination Figure 1 , Figure 3 , Figure 6 and Figure 9 As shown, in some embodiments, the dispensing device further includes a controller 700, which is connected to the first drive unit 111, the second drive unit 3211, the third drive unit 3221, the fourth drive unit, the material detection sensor 600, the vibrator 170, the air supply unit 210, and the robotic arm. The dispensing principle of the dispensing device will be explained below.

[0084] The controller 700 controls the first drive unit 111 to drive the switching block 120 to the target position. In response to the switching block 120 having moved to the target position, the controller 700 activates the vibrator 170 and the air supply unit 210, and controls the second drive unit 3211 to drive the locking assembly 3212 to switch to the locking state. At this time, the bolt to be fed falls through the material channel 123 into the first end of the conduit 220 and is blown to the second end of the conduit 220 by the gas supplied by the air supply unit 210. In response to the material detection sensor 600 detecting that the material to be fed 400 has fallen into the limiting channel 350, the controller 700 controls the third drive unit 3221 to drive the clamping assembly 3222 to move between the positioning member 360 and the locking assembly 3212, and drives the clamping assembly 3222 to switch to the clamping state. In response to the robotic arm stopping, the controller 700 controls the third drive unit 3221 to drive the clamping assembly 3222 to switch to the releasing state, thereby feeding the material to be fed 400 into the designated position.

[0085] In summary, when the production line needs to feed different types of materials 400, the switching block 120 can be moved into place by using the switching cylinder 110 to feed the materials 400 from the corresponding material channel 123 into the conduit 220, and then fed to the designated position. This eliminates the need to move the entire feeding device out of or into the production line, thereby improving the efficiency of feeding materials 400 of different sizes and thus improving the processing efficiency of the production line.
