Description

Technical Field

[0001] This invention relates to the field of automated assembly equipment technology, and more specifically, to an upward-feeding nut delivery gun. Background Technology

[0002] In welding processes in industries such as automobile manufacturing and home appliance production, the automatic feeding and positioning of nuts is a crucial step affecting production efficiency and welding quality. Existing nut feeding devices typically use a vibratory feeder in conjunction with a feeding tube to supply nuts. However, due to the spatial structure of the welding station, the feeding gun needs to be able to adjust the nut's posture within a confined space.

[0003] Existing nut delivery guns typically deliver nutes in a unidirectional downward direction, which cannot fully meet the needs of upward delivery. Furthermore, achieving upward delivery requires the use of robotic arms or similar equipment, which is not only structurally complex and costly, but also requires sensors to detect signals, resulting in low efficiency. Therefore, this application proposes an upward-feeding nut delivery gun to at least partially solve the problems that exist in the prior art. Summary of the Invention

[0004] In view of the aforementioned problems, this application is made in order to provide an upward-feeding nut delivery gun that overcomes or at least partially solves the aforementioned problems.

[0005] To achieve the above objectives, the present invention provides an upward-feeding nut delivery gun, comprising: The curved receiving device has a receiving groove at one end, a first connecting hole in the middle, and a second connecting hole at the other end. The flip-type receiving device bracket has an H-shaped connecting rod embedded in it, and a third connecting hole is provided on it; The first connecting hole is hinged to the third connecting hole, and the second connecting hole is hinged to the first end of the H-shaped connecting rod; The protective sleeve contains a floating feed tube and a mandrel push rod in sequence. The first end of the mandrel top rod is hinged to the second end of the H-shaped connecting rod; The sheath has a fixed limiting sleeve connected to its first end and a first cylinder connected to its second end. The first end of the floating feed tube extends from the fixed limiting sleeve and is connected to the floating feed tube connector; the floating feed tube connector is connected to the flip-feeder bracket. The second end of the mandrel push rod is connected to the push rod of the first cylinder and is fitted with a first spring, which abuts against the second end of the floating feed tube and the push rod of the first cylinder.

[0006] Optionally, the fixed limiting sleeve is further provided with a distributor connecting sleeve; The distributor connecting sleeve is provided with a distributor assembly adapted to the receiving device.

[0007] Optionally, the distributor assembly includes a first distributor for adapting flange nuts and a second distributor for adapting ordinary nuts.

The other end of the air blowing pipe is connected to one end of the slide; the slide is equipped with a second cylinder and a third cylinder in alternating states, and a sensor is also provided on the slide; the other end of the slide is connected to a nut conveying device.

[0009] Optionally, the sidewall of the slide is an asymmetrical structure with one side lower and the other side higher.

[0010] Optionally, the sensor is located at the upper end of the slide and is offset from the center of the slide, wherein the center of the sensor is biased toward the lower side of the slide wall.

[0011] Optionally, the second distributor includes: The mounting base has a movable conveyor assembly and a fixed conveyor assembly inside it; The movable conveying component has an output port at its front end corresponding to the receiving trough, and is hinged to the mounting base near the output port; the movable conveying component has a first channel inside, and a protrusion at its lower end; the lower end of the first channel has an adapter groove. The fixed conveying assembly is provided with a second channel that matches the first channel; The mounting base is also provided with a blocking post; The protrusion extends and protrudes from the bottom of the mounting base; The mounting base is detachably equipped with a pressure cover at its upper end; the pressure cover is connected to the movable conveying assembly via a second spring. When the protrusion moves to the mounting base and then onto the tilting feeder bracket, the first and second channels are misaligned; when the protrusion is suspended, the movable conveying assembly moves down, connecting the first and second channels, and the blocking post extends into the adapter groove.

[0012] Optionally, the protrusion may also be provided with a pulley.

[0013] Optionally, both the first distributor and the second distributor are provided with a pipe clamp for connecting the conveying pipe; wherein, the pipe clamp of the first distributor is located at the tail of the dispensing head and is used to connect the end conveying pipe; the pipe clamp of the second distributor is located at the tail of the mounting base and is used to connect the nut conveying device.

[0014] Optionally, the sheath is also provided with an adjustable feed tube support.

[0015] Optionally, the bottom of the receiving trough is also provided with a small hole.

[0016] Optionally, the distributor connecting sleeve consists of two pieces connected to each other by screws; it can be used to adjust the position of the distributor connecting sleeve, wherein the distributor connecting sleeve is also provided with screw holes for installing the distributor assembly.

[0017] In some embodiments of this application, a feeding method based on an upward-feeding nut delivery gun includes the following steps: The push rod of the first cylinder extends, pushing the mandrel push rod and the floating feed tube forward synchronously; After the floating feed tube is stopped by the limit switch, the mandrel push rod continues to advance and compress the first spring; The mandrel push rod drives the curved feeder to flip upwards via the H-shaped connecting rod, feeding the nut upwards; The push rod of the first cylinder retracts, the mandrel push rod retracts, the first spring returns to its original position, and the receiving device flips downwards to flatten itself. The first cylinder continues to contract, causing the mandrel push rod and the floating feed tube to retract synchronously, so that the entire receiver is reset to the receiving position.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: By coordinating the first cylinder, the first spring, the H-shaped connecting rod, and the curved receiving device, the upward rotation of the receiving device is driven by the stroke difference between the mandrel push rod and the floating feed tube. No additional sensors, robotic arms, or complex electrical control timing are required; the upward feeding of nuts can be completed solely through the mechanical linkage of pneumatic components, reducing equipment costs and control complexity. The floating feed tube and mandrel push rod are sequentially housed within the sheath, resulting in a slender, spear-shaped overall structure that occupies minimal space. This allows for flexible placement in the confined spaces of welding stations in automotive manufacturing and home appliance production, solving the problem of traditional upward feeding mechanisms requiring significant installation space. The first spring serves both to transmit thrust and to provide cushioning during the reset process, preventing rigid impacts. Simultaneously, the spring's compression stroke allows the mandrel push rod to continue advancing relative to the floating feed tube, ensuring the receiving device is rotated into position. During cylinder reset, the receiving device automatically flattens and retracts, achieving stable cyclic operation. By setting a distributor connecting sleeve adapted to the receiving device, a first distributor (for flange nuts) or a second distributor (for ordinary nuts) can be installed, enabling rapid switching between different nut specifications and improving the equipment's versatility and production flexibility. The slide of the first distributor adopts an asymmetrical sidewall structure with one side lower and the other higher, effectively limiting the vertical movement of the flange nuts during conveying; at the same time, the sensor is set off-center to avoid false or missed detections caused by the nut's center hole, improving feeding stability and detection accuracy. The second distributor, through the cooperation of the protrusion at the lower end of the movable conveying component with the position of the flip receiving device bracket, realizes the automatic staggering or connection between the first and second channels, and, with the help of the blocking column, controls the nuts to be released one by one. No independent drive source is required, the structure is simple and not prone to jamming. The small hole at the bottom of the receiving groove can instantly expel air from the groove when the nut falls in, preventing the nut from shifting due to air pressure obstruction, further improving the accuracy of feeding positioning. The protrusion of the second distributor is equipped with a pulley, which converts sliding friction into rolling friction, reducing wear during long-term operation and ensuring operational accuracy and product life.

Detailed Implementation

[0030] 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 only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Please see Figures 1 to 4As shown, this embodiment of the invention provides an upward-feeding nut conveying gun, comprising: a curved receiving device 106, preferably L-shaped in cross-section, with a receiving groove 161 at one end, a first connecting hole 162 in the middle, and a second connecting hole 163 at the other end; a flip-up receiving device bracket 105, in which an H-shaped connecting rod 107 is embedded, and a third connecting hole is provided on it; the first connecting hole 162 is hinged to the third connecting hole, and the second connecting hole 163 is hinged to the first end of the H-shaped connecting rod 107; a protective sleeve 101, in which a floating feeding tube 109 and a mandrel push rod 110 are sequentially sleeved; the first end of the mandrel push rod 110 is hinged to the second end of the H-shaped connecting rod 107; the protective sleeve 101 has a fixed limiting sleeve 102 connected to its first end and a first cylinder 103 connected to its second end; the first end of the floating feeding tube 109 extends from the fixed limiting sleeve 102. It extends out and connects to the floating feed tube connector 104; the floating feed tube connector 104 is connected to the flipper bracket 105; the second end of the spindle push rod 110 is connected to the push rod of the first cylinder 103 and is fitted with a first spring 111, and the first spring 111 abuts between the second end of the floating feed tube 109 and the push rod of the first cylinder 103.

[0032] The above structure ensures that the displacement stroke of the mandrel push rod 110 is greater than the stroke stroke of the floating feed tube 109, and this distance is equal to the compression stroke of the spring. During operation, in the initial state of the first cylinder 103 (i.e., the retracted state of the cylinder), the receiving groove 161 of the receiver 106 is located in the receiving position to receive materials. Then, the push rod of the first cylinder 103 pushes the mandrel push rod 110 while simultaneously pushing the floating feed tube 109 through the first spring 111 until the first spring 111 pushes the floating feed tube 109 to the limit. At this point, the floating feed tube 109 no longer moves forward, but due to the spring, the first cylinder 103 can still push the mandrel push rod 110 forward. Simultaneously, the spring is compressed; when the mandrel push rod 110 is initially pushed, the floating feed tube 109 is in a relatively stationary state, causing the receiver 106 to flip upward, thus completing the upward flipping conveying; after the feeding process is completed, the first cylinder 103 resets, firstly causing the first spring 111 to reset and the mandrel push rod to retract towards the floating feed tube 109, so that the receiver 106 returns from the flipped state to the straight state. Then, during the further reset stroke of the cylinder, it drives the mandrel push rod 110 and the floating feed tube 109 to retract and reset synchronously, thereby driving the flipping receiver bracket 105 and the receiver 106 to the position until the cylinder is in the retracted state. At this time, the receiver 106 is in the receiving position of the next round, thus performing cyclic work.

[0033] It should be noted that, in order to achieve better feeding, a suction device can be set at the target position to attract the target. For example, a magnet and a vacuum can be used to attract the metal nut.

[0034] Furthermore, the fixed limiting sleeve 102 is also provided with a distributor connecting sleeve 108; the distributor connecting sleeve 108 is provided with a distributor assembly adapted to the receiving device 106. This is used to install the distributor assembly, enabling automatic material feeding and further improving the level of automation.

[0035] The distributor assembly includes a first distributor for fitting flange nuts and a second distributor for fitting ordinary nuts.

[0036] In some embodiments of this application, such as Figures 5 to 7 As shown, the first distributor includes: a distributor body mounted on the nut conveyor body; the distributor body includes an air blowing pipe 202, an air blowing head 203, a slide rail 204, a second cylinder 205 and a third cylinder 206, and a sensor 207; a distribution head 201, which is mounted on the distributor connecting sleeve 108 and connected to one end of the air blowing pipe 202 through a conveying pipe; the air blowing head 203 is disposed on the air blowing pipe 202; the other end of the air blowing pipe 202 is connected to one end of the slide rail 204; the slide rail The slide 204 is equipped with a second cylinder 205 and a third cylinder 206 operating in alternating states, and a sensor 207 is also provided on the slide. The other end of the slide 204 is connected to a nut conveying device. Specifically, the nut conveying device includes a vibrating plate, wherein the nuts output by the vibrating plate are conveyed directly (the track of the vibrating plate is directly connected to the end of the slide 204) or indirectly (the track of the vibrating plate can be directly connected to the end of the slide 204 via a conveying pipe or other means) to the position of the slide 204 of the distributor via a track on the vibrating plate. The aforementioned sensor 207 is used to detect whether there is a flange nut in the slide 204.

[0037] It should be noted that a flange nut is a nut with a flange, meaning the flange and nut are manufactured by welding or as a single piece. When the nut enters the air blowing pipe, the second cylinder 205 extends, preventing the following screws from entering the air blowing pipe 202 together with the previous nut, ensuring that only one nut enters the air blowing pipe 202 at a time. The nut entering the air pipe is transported by the strong airflow from the air blowing head through the conveying pipe to the distribution head 201 of the first distributor, and then to the receiving device 106. When it is necessary to blow out the second nut, the second cylinder 205 retracts, and the third cylinder 206 extends, allowing a nut to slide from the slide rail 204 into the air blowing pipe position. At this time, the nuts queuing behind are blocked by the third cylinder 206.

[0038] Furthermore, the sidewall of the slide 204 has an asymmetrical structure with one side lower and the other side higher. This asymmetrical structure allows the lower side of the slide 204 to provide a certain degree of restraint during flange nut transport, preventing issues such as flange stacking or nut tipping over due to varying flange thicknesses or thinner flanges. The lower side also limits the upward movement of the flange, making flange nut transport smoother.

[0039] Furthermore, the sensor 207 is located at the upper end of the slide rail 204 and is offset from the center of the slide rail 204, wherein the center of the sensor 207 is biased towards the lower side of the slide rail 204 wall. This eccentrically positioned sensor avoids the problem of false detection or missed detection caused by a hollow center in the nut.

[0040] In other embodiments of this application, such as Figure 8 and Figure 9 As shown, the second distributor includes: a mounting base 301, which houses a movable conveying assembly 304 and a fixed conveying assembly 305; the movable conveying assembly 304 has an output port at its front end corresponding to the receiving groove 161, and is hinged to the mounting base 301 near the output port; the movable conveying assembly 304 has a first channel 341 inside, and a protrusion 343 at its lower end; the lower end of the first channel 341 has an adapter groove 342; the fixed conveying assembly 305 has a second channel 351 that matches the first channel 341; the mounting base 301 also has a blocking post 311; the protrusion 343 extends and protrudes from the bottom of the mounting base 301; a pressure cap 303 is detachably provided on the upper end of the mounting base 301; the pressure cap 303 is connected to the movable conveying assembly 304 by a second spring. Figure 8 and Figure 9 As shown, the combination of the pressure cap 303 and the movable conveying assembly 304 forms a structure that can be quickly assembled and disassembled, with a quick disassembly function, which facilitates quick replacement and troubleshooting in case of failure.

[0041] When the protrusion 343 moves to the mounting base 301 and onto the flipper bracket 105, the first channel 341 and the second channel 351 are misaligned and not connected. The lower end of the first channel 341 blocks the second channel 351, and the upper end of the blocking post 311 extends from the first channel 341 into the adapter groove 342, making the first channel 341 unobstructed, thus allowing the nut inside to fall into the receiving groove 161 of the receiver 106. When the protrusion 343 is suspended, the movable conveying assembly 304 moves downward, connecting the first channel 341 and the second channel 351, and the blocking post 311 extends to the adapter groove 342. Within the trough 342, specifically, this state corresponds to the feeding state of the receiving device 106; wherein, the second spring moves the movable conveying component 304 downward, thereby connecting the first channel 341 and the second channel 351, so that the nut in the second channel 351 enters the blocking post 311 in the first channel 341 and is blocked; when the first cylinder 103 is reset, the movable conveying component 304 moves to a position above the receiving device 106 and the flipping receiving device bracket 105, thereby allowing the nut to enter the receiving trough 161 of the receiving device 106 from the first channel 341.

[0042] Furthermore, a pulley 344 is also provided at the position of the protrusion 343. When the lower end of the movable conveying component 304 and the flipper bracket 105 come into contact with each other through the pulley 344, the sliding friction is changed into rolling friction, which prevents the protrusion 343 from being worn down by friction over a long period of time during operation, thus preventing problems such as reduced accuracy.

[0043] Both the first distributor and the second distributor are provided with a material pipe clamp 302 for connecting a material conveying pipe. The material pipe clamp 302 of the first distributor is located at the tail of the distribution head 201 and is used to connect the end conveying pipe. The material pipe clamp 302 of the second distributor is located at the tail of the mounting base 301 and is used to connect a nut conveying device. For example, a flexible material conveying pipe can be fixedly connected by the material pipe clamp 302 to facilitate the conveying of materials.

[0044] Furthermore, the sheath 101 is also provided with an adjustable material tube support 112. This facilitates the installation and fixation of the device, as well as the adjustment of the installation angle of the device.

[0045] The bottom of the receiving groove 161 is also provided with a small hole 164. The shape, size and depth of the receiving groove 161 can be set according to different nut requirements. Different sizes of receiving devices 106 can also be replaced to adapt to different sizes of nuts, thereby increasing adaptability. In addition, the air pressure of the receiving groove 161 can be balanced through the small hole 164 to make the feeding more accurate.

[0046] It should be noted that when the nut falls into the receiving groove 161, if the speed is too fast or the bottom of the nut is closed, the air in the receiving groove cannot be discharged in time when the nut falls, causing the nut to deviate, which further makes the feeding more accurate.

[0047] Furthermore, the distributor connecting sleeve 108 consists of two parts connected to each other by screws; it can be used to adjust the position of the distributor connecting sleeve 108, wherein the distributor connecting sleeve 108 is also provided with screw holes, such as... Figure 4 As shown, this is used to install the distributor components. Figure 5 and Figure 8 As shown, this allows the distributor to better cooperate with the receiver 106.

[0048] This application also discloses a feeding method based on an upward-feeding nut delivery gun, comprising the following steps: Step S1: Initial material receiving. The first cylinder 103 is in the retracted state, and the mandrel push rod 110 and the floating feed tube 109 are both in the retracted position. The receiving groove 161 of the curved material receiver 106 is in the receiving position to receive the nut from the distributor assembly.

[0049] Step S2: Synchronous advancement, the push rod of the first cylinder 103 extends, pushing the mandrel push rod 110 forward; the mandrel push rod 110 pushes the floating feed tube 109 forward synchronously through the first spring 111.

[0050] Step S3: Floating feed tube is limited. When the floating feed tube 109 moves to the point where its front end is limited by the fixed limiting sleeve 102, the floating feed tube 109 stops moving. At this time, the mandrel push rod 110 continues to move forward under the push of the first cylinder 103 and compresses the first spring 111.

[0051] Step S4: The feeder flips upward to feed the material, and the mandrel push rod 110 continues to move forward, pushing the first end of the H-shaped connecting rod 107 that is hinged to it; the H-shaped connecting rod 107 rotates around its hinge point with the flip feeder bracket 105, and its second end pushes the middle of the curved feeder 106, causing the feeder 106 to flip upward around its hinge point with the flip feeder bracket 105, and conveying the nut in the receiving groove 161 upward to the target welding position.

[0052] Step S5: The cylinder resets and the receiving device returns to its flat position. The push rod of the first cylinder 103 retracts, the spindle push rod 110 retracts, and the first spring 111 returns to its original deformation. The H-shaped connecting rod 107 rotates in the opposite direction, causing the receiving device 106 to flip downwards and reset to a flat state.

[0053] Step S6: The whole structure retracts and resets. The first cylinder 103 continues to retract, driving the spindle push rod 110 and the floating feed tube 109 to retract synchronously. The floating feed tube connector 104 pulls the flip-over receiving bracket 105 and the receiving device 106 back to the initial position. The receiving slot 161 is re-aligned with the distributor assembly, ready for the next receiving.

[0054] In this application, a slender gun-shaped structure is formed by coaxially sleeved sheath, floating feed tube, and mandrel push rod; the linear motion of the mandrel push rod is converted into the flipping motion of the receiving device through an H-shaped connecting rod; the timing control of the floating feed tube being limited first and the mandrel push rod continuing to advance is achieved by utilizing the compression stroke difference of the first spring; and a replaceable distributor assembly is provided (the first distributor is adapted to a flange nut, and the second distributor is adapted to a regular nut) to enhance versatility.

[0055] When the first cylinder extends, the floating feed tube is first limited, and the spindle push rod continues to compress the spring and move forward, pushing the H-shaped connecting rod to make the receiver flip upward and complete the feeding. When the first cylinder retracts, the spring first resets to make the receiver return to the flat position, and then the whole thing retracts to make the receiver move back to the receiving position, forming a complete working cycle. The whole process does not require sensors or electrical control timing, it is purely mechanical linkage, and the action is reliable.

[0056] In this application, pure pneumatic drive eliminates the need for robotic arms or sensors, reducing system complexity and cost; the gun-shaped structure occupies little space and is easy to arrange at the welding station; the spring travel difference is used to achieve precise timing, avoiding rigid impact and providing high feeding frequency; the distributor can be quickly replaced to transport flange nuts or ordinary nuts; details such as asymmetrical slides, eccentric sensors, and pulley protrusions improve conveying reliability.
