Description

Technical Field

[0001] This invention relates to the field of lithium battery manufacturing equipment technology, and in particular to an automatic feeding device with a suction nozzle. Background Technology

[0002] The new energy industry is currently developing rapidly, with the production scale of lithium batteries expanding year by year, and the functions of lithium battery manufacturing equipment becoming increasingly sophisticated. For manufacturers of square aluminum-cased lithium batteries, the ability to quickly and efficiently meet production testing needs in lithium battery manufacturing equipment has significant economic value.

[0003] In the lithium battery manufacturing process, the formation stage often uses a negative pressure system to collect and treat the waste gas generated during the formation process. During this process, due to the vaporization of the electrolyte and the electrolyte remaining in the negative pressure pipeline, the residual electrolyte will crystallize in the negative pressure system at the high temperature in the formation workshop. This crystallization can cause the nozzle to become clogged, resulting in a large number of battery failures and incalculable losses.

[0004] To address the aforementioned issues, a nozzle insertion fixture and a nozzle removal fixture are typically provided to replace clogged nozzles. First, the nozzle removal fixture is placed in the storage location to remove the clogged nozzles from the negative pressure module. Then, the nozzle insertion fixture is used to automatically install the negative pressure nozzles.

[0005] When inserting a nozzle, the nozzle must first be placed on the nozzle insertion fixture. Currently, the common practice is to manually place the nozzle on the nozzle insertion equipment, and then put the nozzle insertion fixture into the storage position to perform the nozzle insertion action. When completing one storage position, manual loading of the fixture is required from the maintenance side. This operation method requires manual intervention, which is time-consuming, labor-intensive, extremely inefficient, and has high labor costs, making it unable to meet the needs of large-scale production.

The first suction nozzle assembly is fixedly connected to the mounting base, and the second suction nozzle assembly is slidably mounted on the mounting base in the X direction. A connecting plate is connected between two adjacent groups of suction nozzle assemblies. The connecting plate is provided with a connecting groove extending in the X direction. The length of the connecting groove is equal to the distance between two adjacent suction nozzles on the suction nozzle tooling. Two adjacent suction nozzle assemblies are provided with a stop member that passes through the connecting groove and engages with the groove wall in the X direction. The X-direction moving module is drivenly connected to the second suction nozzle assembly to drive the second suction nozzle assembly to move in the X direction.

[0015] Preferably, the positioning unit includes a coarse positioning module for supporting the nozzle insert fixture, a blocking module for positioning the nozzle insert fixture in the X direction, and a lifting module for lifting the nozzle insert fixture.

The lifting frame is also provided with a positioning pin for inserting and cooperating with the nozzle insert fixture and a fine positioning sensor for detecting the assembly accuracy with the nozzle insert fixture.

[0016] Preferably, the lifting frame includes a lifting plate, a guide shaft, and a connecting rod plate. The lifting plate and the connecting rod plate are arranged parallel to each other and spaced apart in the Z direction. The guide shaft is vertically connected between the lifting plate and the connecting rod plate. The lifting cylinder is fixed on the base and is drivenly connected to the lifting plate. The positioning pin and the precision positioning sensor are both arranged on the lifting plate. The bottom of the lifting plate and the top of the connecting rod plate are provided with limiting rods that are stopped and assembled with the base in the Z direction.

Then, the nozzles are placed in the vibrating plate. The vibrating plate arranges the nozzles in a spiral sequence through vibration and passes them through the straight vibration feeder. The straight vibration feeder arranges the nozzles into a single straight line and conveys them to the material trough on the picking platform. Then, the Y-axis moving module and Z-axis moving module of the transfer unit cooperate to move the nozzle clamping module to the upper side of the picking platform. The drive unit drives the gripper to clamp the nozzles on the picking platform, and then the transfer unit transfers the nozzle clamping module and the nozzles on it.

[0037] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0038] A preferred embodiment of the automatic feeding device for inserting suction nozzles according to the present invention is as follows: Figures 1 to 15 As shown, the automatic feeding device for inserting suction nozzles includes a base 1, a positioning unit 2, a transfer unit 4, a feeding unit 3, and a suction nozzle clamping module 5. The base 1 is the supporting foundation for the entire device and is used to arrange the various equipment structures. The positioning unit 2, the transfer unit 4, the feeding unit 3, and the suction nozzle clamping module 5 are all arranged on the base 1.

[0039] The base 1 includes a base plate 11 and a mounting frame 12. The base plate 11 is the substrate of the base 1 and has a rectangular plate structure. The mounting frame 12 is fixed to the base plate 11 by bolts. The positioning unit 2 and the feeding unit 3 are both mounted on the base plate 11, and the transfer unit 4 is mounted on the mounting frame 12. The mounting frame can support the weight of the transfer unit 4 and raise its height, so that there is space between the transfer unit 4 and the base plate 11 for installing various devices. The suction nozzle module 5 is fixedly mounted on the bottom of the transfer unit 4 and is used to clamp or release the suction nozzle to be assembled. In this embodiment, the mounting frame 12 is a rectangular frame structure formed by welding plates. The plates can be existing profile structures, which will not be described in detail here.

[0040] The positioning unit 2 is used to support and position the nozzle insertion fixture 9 to be assembled, and to position the nozzle insertion fixture 9 to ensure that the position of the nozzle insertion fixture 9 is consistent each time a nozzle is assembled, so as to meet the needs of automatic nozzle feeding.

[0041] The feeding unit 3 is the feeding part of the entire device, used to provide the nozzles required by the nozzle insertion tooling 9. The feeding unit 3 includes a vibratory feeder 31, a direct vibration feeder 32, and a pick-up table 33 connected in sequence. The vibratory feeder 31 can temporarily store the nozzles to be assembled. The operator can directly put the nozzles into the vibratory feeder 31. The vibratory feeder 31 conveys the nozzles to the required state to the direct vibration feeder 32 through vibration and spiral grooves. The direct vibration feeder 32 conveys the single-row arranged nozzles to the pick-up table 33 through vibration. The specific structure of the vibratory feeder 31 and the direct vibration feeder 32 is prior art and will not be described in detail here.

[0042] The picking platform 33 is used to store the nozzles arranged in a single row, so that the nozzle clamping module 5 can clamp the nozzles and transfer them to the nozzle insertion fixture 9. Between the picking platform 33 and the direct vibration feeder 32, there is a sequentially connected material trough 34 for the single-row arrangement of nozzles. The material trough 34 can limit the transport direction of the nozzles, and its width can only accommodate a single row of nozzles, ensuring that the nozzles are arranged in a single row for the clamping module 5 to grasp. The picking platform 33 and the positioning unit 2 are arranged at intervals along the Y direction. The transfer unit 4 can drive the nozzle clamping module 5 to move in the Y direction, so that the nozzle clamping module 5 reciprocates between the picking platform 33 and the positioning unit 2, transferring the nozzles from the picking platform 33 to the nozzle insertion fixture 9 on the positioning unit 2.

[0043] Specifically, the material handling platform 33 includes a material handling plate 331, connecting rods 332, a bottom assembly plate 333, guide strips 334, and a stop sheet metal 335. The material handling plate 331 and the bottom assembly plate 333 are parallel to each other and arranged vertically at intervals. There are four sets of connecting rods 332 arranged discretely in a matrix. The four sets of connecting rods 332 are vertically connected between the material handling plate 331 and the bottom assembly plate 333. The bottom assembly plate 333 is fixedly mounted on the base plate 11.

[0044] There are two sets of guide bars 334, each extending along the X direction. The two sets of guide bars 334 are spaced apart along the Y direction, and the gap between the two sets of guide bars 334 forms a material trough 34 for a single row of suction nozzles. A stop sheet metal 335 is arranged at the tail end of the material trough 34 to limit the suction nozzles. When the suction nozzles are conveyed into the material trough 34, the suction nozzles at the tail end are stopped and assembled with the stop sheet metal 335 to prevent the suction nozzles from falling off the pick-up table 33.

[0045] Sensors are also arranged on the guide bar 334 to detect whether the material trough 34 is full of suction nozzles. The sensors are through-beam sensors, with one set at each end of the guide bar 334. When the material trough 34 is full of suction nozzles, the nozzles block the signal emitted by the sensors, thus determining whether the material trough 34 is full. In this embodiment, the guide bar 334 of the feeding platform 33 can accommodate 12 suction nozzles. In other embodiments, the number of suction nozzles that can be accommodated can be adjusted by changing the model of the feeding platform 33.

[0046] The transplanting unit 4 includes a Y-axis moving module 41 and a Z-axis moving module 42. The Y-axis moving module 41 is arranged on the base 1 and can move along the Y-axis. The Z-axis moving module 42 is arranged on the Y-axis moving module 41 and can move in the Z-axis direction. The X, Y, and Z axes are perpendicular to each other. The X and Y axes extend in the horizontal plane, and the Z axis extends in the vertical direction.

[0047] The Z-axis moving module 42 is connected to the suction nozzle module 5 via a transmission. The Z-axis moving module 42 can drive the suction nozzle module 5 to move up and down in the Z-axis direction, and the Y-axis moving module 41 can drive the Z-axis moving module 42 to move in the Y-axis direction. In turn, the Z-axis moving module 42 drives the suction nozzle module 5 to move in the Y-axis direction, so that the suction nozzle module 5 can reciprocate between the picking platform 33 and the positioning unit 2, assembling the suction nozzle in the picking platform 33 into the suction nozzle insertion fixture 9 of the positioning unit 2. The Z-axis moving module 42 and the Y-axis moving module 41 cooperate with each other to realize the position adjustment of the suction nozzle module 5 in the Y and Z directions, and complete the transfer of the suction nozzle.

[0048] The suction nozzle module 5 includes a mounting base 51, a suction nozzle assembly 52, an X-axis moving module 53, and a drive unit 54. The mounting base 51 is assembled and connected to the Z-axis moving module 42. The suction nozzle assembly 52, the X-axis moving module 53, and the drive unit 54 are all mounted on the mounting base 51. When the Z-axis moving module 42 drives the mounting base 51 to move in the Z-axis, it can simultaneously drive the suction nozzle assembly 52 on it to move in the Z-axis, thereby completing the Z-axis position adjustment of the suction nozzle.

[0049] The nozzle assembly 52 is slidably mounted on the mounting base 51 along the X-axis. Multiple sets of nozzle assemblies 52 are arranged side by side along the X-axis, each set of nozzle assemblies 52 is used to clamp and assemble one nozzle. The specific number of nozzle assemblies 52 is determined according to the number of nozzles assembled on the nozzle insertion fixture 9. The X-axis moving module 53 is driven by the nozzle assembly 52 to drive the nozzle assembly 52 to move along the X-axis on the mounting base 51. After the X-axis moving module 53 drives the nozzle assembly 52 to move in the X-axis, the X-axis position of the nozzle clamped by the nozzle assembly 52 can be adjusted so that it corresponds to the position of the fixing sleeve of the nozzle to be assembled on the nozzle insertion fixture 9. Through the cooperation of the X-axis moving module 53, the Y-axis moving module 41 and the Z-axis moving module 42, the three-way position adjustment of the nozzle assembly 52 can be realized, the placement distance of the nozzle can be controlled, and the nozzle can be accurately placed in the nozzle insertion fixture 9.

[0050] Each set of nozzle assemblies 52 has the same structure, and only one set is described here as an example. The nozzle assembly 52 includes an adapter plate 521 and a gripper 522. The gripper 522 is arranged and fixed on the adapter plate 521. The adapter plate 521 is slidably assembled with the mounting base 51 in the X direction, and the adapter plate 521 is connected to the X-direction moving module 53. The X-direction moving module 53 drives the adapter plate 521 to move in the X direction, thereby driving the gripper 522 and the nozzle to move in the X direction.

[0051] The gripper 522 is used to hold the nozzle. The drive unit 54 is fixedly mounted on the mounting base 51, and the drive unit 54 is kinetically connected to the gripper 522 to drive the gripper 522 to hold or release the nozzle. When the nozzle-holding module 5 moves above the loading table 33, the drive unit 54 drives the gripper 522 to open and hold the nozzle. When the nozzle-holding module 5 moves above the nozzle insertion fixture 9, the drive unit 54 drives the fixture to open and release the nozzle. The nozzle can be mounted on the nozzle-holding fixture.

[0052] Specifically, in this embodiment, the mounting base 51 includes a top plate 511 and a mounting plate 512, which are arranged perpendicularly to each other. A floating joint 6 is mounted on the upper side of the top plate 511, and the floating joint 6 is connected to the Z-axis moving module 42. The mounting plate 512 is located below the top plate 511 and is fixedly connected to the top plate 511. The X-axis moving module 53 is fixedly assembled at the bottom of the top plate 511, and the suction nozzle assembly 52 is slidably assembled on the mounting plate 512 along the X-axis.

[0053] The mounting plate 512 is also equipped with linear guides 513 extending along the X direction. Two sets of linear guides 513 are arranged at intervals along the Z direction. The adapter plate 521 of the nozzle assembly 52 is guided and mounted on the linear guides 513. The linear guides 513 guide the movement of the nozzle assembly 52 and reduce the resistance to the movement of the nozzle assembly 52. ​​The drive unit 54 is fixedly mounted on the back side of the mounting plate 512 to drive the clamping and releasing action of the gripper 522 along the Y direction.

[0054] Specifically, in this embodiment, the X-axis moving module 53 includes a motor 531, a coupling 532, a lead screw assembly 533, and a lead screw connecting block 534. The lead screw assembly 533 extends along the X-axis. The motor 531 is fixedly mounted on the bottom of the top plate 511. The motor 531 and the lead screw assembly 533 are connected by the coupling 532, and the motor 531 can drive the lead screw assembly 533 to rotate. The lead screw connecting block 534 is threaded onto the lead screw assembly 533 and is fixedly connected to the adapter plate 521 of the nozzle assembly 52. ​​When the lead screw assembly 533 rotates, it can drive the lead screw connecting block 534 to slide along the X-axis, thereby driving the adapter plate 521 to slide along the X-axis on the rail 513, adjusting the X-axis position of the nozzle assembly 52.

[0055] When it is necessary to feed the nozzle insertion fixture 9, the operator can first place the nozzle insertion fixture 9 on the positioning unit 2, and position the nozzle insertion fixture 9 through the positioning unit 2. Then, the nozzle is placed in the vibratory feeder 31. The vibratory feeder 31 arranges the nozzles in a spiral sequence through vibration and passes them through the linear vibratory feeder 32. The linear vibratory feeder 32 arranges the nozzles into a single straight line and conveys them to the material trough 34 on the picking platform 33. Then, the Y-axis moving module 41 and the Z-axis moving module 42 of the transfer unit 4 cooperate to move the nozzle clamping module 5 to the upper side of the picking platform 33. The drive unit 54 drives the gripper 522 to clamp the nozzles on the picking platform 33, and then the transfer unit 4 moves the nozzle clamping module 5 and the nozzles on it to the nozzle insertion fixture 9. On the upper side, the X-direction moving module 53 drives each group of suction nozzle assemblies 52 to move along the X-direction so that each group of suction nozzle assemblies 52 corresponds one-to-one with the suction nozzle assembly position on the insertion suction nozzle fixture 9. The driving unit 54 drives the gripper 522 to release the suction nozzle, thus assembling the suction nozzle into the insertion suction nozzle fixture 9. Through the cooperation of various structures, the suction nozzle can be accurately and automatically placed into the insertion suction nozzle fixture 9. The operator only needs to put the suction nozzle into the vibrating plate 31, which reduces the manual intervention in the placement of the suction nozzle and the labor cost, reduces the safety risk of the equipment to the operator, improves the efficiency of placing the suction nozzle into the insertion suction nozzle fixture 9, realizes the automatic feeding function of the insertion suction nozzle fixture 9, meets the needs of large-scale production, and also leaves sufficient operating space for daily equipment maintenance.

[0056] Preferably, the gripper 522 includes a fixed clamp 5221, a movable clamp 5222, and an elastic reset member. The fixed clamp 5221 and the movable clamp 5222 are provided with half-grooves on their opposite sides. After the half-grooves on the fixed clamp 5221 and the movable clamp 5222 are engaged, the suction nozzle can be clamped. The drive unit 54 is connected to the movable clamp 5222 to drive the half-grooves to open. The elastic reset member is connected between the fixed clamp 5221 and the movable clamp 5222 to drive the half-grooves to engage.

[0057] The fixed clamp 5221 and the movable clamp 5222 fix the suction nozzle through their respective semi-grooves. When the semi-grooves are engaged, they can hold the suction nozzle; when they are disengaged, they can release the suction nozzle, simplifying the specific structure of the clamp 522. The drive unit 54 is connected to the movable clamp 5222. The drive unit 54 can drive the movable clamp 5222 to open, and the elastic reset member can drive the movable frame to close. The opening and closing of the movable clamp 5222 are handled separately by the drive unit 54 and the elastic reset member, simplifying the transmission connection between the drive unit 54 and the movable clamp 5222 and facilitating the maintenance and replacement of the suction nozzle assembly 52 and the drive unit 54.

[0058] In this embodiment, the fixed clamp 5221 and the movable clamp 5222 are arranged side by side along the Y direction. The movable clamp 5222 can move along the Y direction. The half-grooves on the fixed clamp 5221 and the movable clamp 5222 are formed on their opposite end faces. The movable clamp 5222 moves along the Y direction to realize the engagement and opening of the half-grooves.

[0059] Preferably, the movable clamp 5222 is also connected to a spring shaft 5223. The spring shaft 5223 is inserted into the fixed clamp 5221 along the snapping direction of the half groove. The elastic reset member is a compression spring 523 that presses against the fixed clamp 5221 and the spring shaft 5223. The end of the spring shaft 5223 away from the movable clamp 5222 is press-fitted to the drive unit 54.

[0060] The spring shaft 5223 on the movable clamp 5222 is inserted into the fixed clamp 5221. During the movement of the movable clamp 5222 along the Y direction, the spring shaft 5223 guides the movement of the movable clamp 5222, ensuring the direction of movement of the movable clamp 5222. The drive unit 54 is press-fitted with the spring shaft 5223, so there is no specific connection between the drive unit 54 and the gripper 522, simplifying the assembly form between the drive unit 54 and the movable clamp 5222.

[0061] The compression spring 523 is press-fitted between the fixed clamp 5221 and the spring shaft 5223. In this embodiment, one end of the spring shaft 5223 has a shaft cap. One end of the compression spring 523 presses against the shaft cap, and the other end presses against the end face of the fixed clamp 5221. The compression spring 523 applies an elastic force to the movable clamp 5222 towards the fixed clamp 5221 through the spring shaft 5223, driving the movable clamp 5222 to engage with the semi-groove on the fixed clamp 5221, so as to ensure that the movable clamp 5222 and the semi-groove on the fixed frame can grip the suction nozzle and realize the feeding function.

[0062] Preferably, the drive unit 54 includes a drive cylinder 541 and a push plate 542 that is pulverizedly connected to the drive cylinder 541. The push plate 542 extends along the X direction, and the drive cylinder 541 is used to drive the push plate 542 to move in the Y direction to press the spring shaft 5223 to move.

[0063] The drive cylinder 541 and the push plate 542 form a drive unit 54. The push plate 542 extends along the X direction, meaning that the push plate 542 and the nozzle assembly 52 are arranged in the same direction. When the nozzle assembly 52 moves along the X direction under the action of the X-direction moving module 53, the push plate 542 can compensate for the positional change of the nozzle assembly 52 by its own length, satisfying the pushing action on the spring shafts 5223 on each set of grippers 522, ensuring that the pushing moving clamp 5222 moves and the half-slot opens. In this embodiment, a floating joint 6 is installed on the push plate 542, and the drive cylinder 541 is fixedly connected to the push plate 542 through the floating joint 6. The floating joint 6 can compensate for the positional offset when the push plate 542 pushes the nozzle assembly 52.

[0064] Preferably, the two sets of suction nozzle assemblies 52 located at both ends of the parallel arrangement of each set of suction nozzle assemblies 52 are defined as the first suction nozzle assembly and the second suction nozzle assembly, respectively. The first suction nozzle assembly is fixedly connected to the mounting base 51, and the second suction nozzle assembly is slidably assembled on the mounting base 51 in the X direction. A connecting plate 7 is connected between two adjacent sets of suction nozzle assemblies 52. A connecting groove 71 extending in the X direction is provided on the connecting plate 7. The length of the connecting groove 71 is equal to the distance between two adjacent suction nozzles on the suction nozzle tooling 9. A stop member is provided on two adjacent suction nozzle assemblies 52, which is inserted into the connecting groove 71 and is engaged with the groove wall of the connecting groove 71 in the X direction. The X-direction moving module 53 is drivenly connected to the second suction nozzle assembly to drive the second suction nozzle assembly to move in the X direction.

[0065] Two adjacent sets of suction nozzle assemblies 52 are fixedly connected in pairs by connecting plates 7. Since the first suction nozzle assembly is fixedly mounted on the mounting base 51, and the positions of the first suction nozzle assemblies are different, when the second suction nozzle assembly moves to the stop and the groove wall of the connecting groove 71 under the action of the X-direction moving module 53, the connecting plate 7 can drive the other adjacent set of suction nozzle assemblies 52 to move, and so on, until each set of suction nozzle assemblies 52 moves to the groove wall of the connecting groove 71. Specifically, in this embodiment, the adapter plate 521 of each suction nozzle assembly 52 is provided with multiple sets of bolt holes, which are arranged at intervals from top to bottom. Each set of bolt holes specifically includes two bolt holes, and bolts are installed in the bolt holes to form a stop.

[0066] In this embodiment, the lead screw connecting block 534 of the X-axis moving module 53 is fixedly connected to the second suction nozzle assembly. Since the length of the connecting groove 71 on the connecting plate 7 is equal to the distance between the two suction nozzles on the suction nozzle fixture 9, when the lead screw connecting block 534 of the X-axis moving module 53 drives the second suction nozzle assembly to move to the maximum displacement on the rail 513, each set of suction nozzle assemblies 52 moves to stop against the groove wall of the connecting groove 71. At this time, the distance between two adjacent sets of suction nozzle assemblies 52 is the distance between two adjacent suction nozzles on the suction nozzle fixture 9. The driving cylinder 541 pushes the spring shaft 5223 to move through the push plate 542, which can drive the half groove to open and release the suction nozzle, so that the suction nozzle can be assembled in the corresponding position of the suction nozzle fixture 9.

[0067] The nozzle assemblies 52 are interconnected via connecting plates 7 and mutually restrained by connecting grooves 71, allowing the nozzle assemblies 52 to move with variable pitch on the rail 513. Each group of nozzle assemblies 52 moves sequentially from the second nozzle assembly to the first nozzle assembly. The lead screw connecting block 534 of the X-axis moving module 53 only needs to be fixedly connected to the second nozzle assembly to realize the movement of each group of nozzle assemblies 52, simplifying the assembly relationship between the X-axis moving module 53 and each group of nozzle assemblies 52.

[0068] Preferably, the positioning unit 2 includes a coarse positioning module 21 for supporting the nozzle insertion fixture 9, a blocking module 22 for positioning the nozzle insertion fixture 9 in the X direction, and a lifting module 23 for lifting the nozzle insertion fixture 9. The lifting module 23 includes a lifting frame 231 that is guided and mounted on the base 1 and a lifting cylinder 232 that drives the lifting frame 231 to rise and fall. The lifting frame 231 is also provided with a positioning pin 233 for inserting and cooperating with the nozzle insertion fixture 9 and a fine positioning sensor 234 for detecting the assembly accuracy with the nozzle insertion fixture 9.

[0069] The coarse positioning module 21 can support the nozzle insertion fixture 9 and simultaneously position the nozzle insertion fixture 9 in the Y direction. When the nozzle insertion fixture 9 is delivered into the device, the blocking module 22 is assembled with the nozzle insertion fixture 9 in the X direction to stop it, which can coarsely position the nozzle insertion fixture 9 in the X direction. Through the positioning effect of the blocking module 22, the nozzle insertion fixture 9 can be placed on the coarse positioning module 21.

[0070] When the lifting cylinder 232 of the lifting module 23 drives the lifting frame 231 to rise and fall on the base 1, the positioning pin 233 of the lifting frame 231 can be inserted into the corresponding position on the nozzle insertion fixture 9 to position the nozzle insertion fixture 9 and lift it to the required position. Then, the precise positioning sensor 234 triggers a signal, and the feeding device can proceed to the next step. Through the cooperation of the positioning pin 233 and the precise positioning sensor 234, the nozzle insertion fixture 9 can be accurately positioned to ensure that the position of the nozzle insertion fixture 9 is consistent.

[0071] In this embodiment, two sets of lifting modules 23 are arranged at intervals along the X direction, and the two sets of lifting modules 23 are arranged symmetrically to ensure that the force is balanced when the nozzle tooling 9 is lifted; multiple sets of coarse positioning modules 21 are arranged discretely to provide stable support for the nozzle tooling 9.

[0072] Preferably, the lifting frame 231 includes a lifting plate 2311, a guide shaft 2312, and a connecting rod plate 2313. The lifting plate 2311 and the connecting rod plate 2313 are arranged parallel to each other and spaced apart in the Z direction. The guide shaft 2312 is vertically connected between the lifting plate 2311 and the connecting rod plate 2313. The lifting cylinder 232 is fixed on the base 1 and is connected to the lifting plate 2311 in a transmission manner. The positioning pin 233 and the precision positioning sensor 234 are both arranged on the lifting plate 2311. The bottom of the lifting plate 2311 and the top of the connecting rod plate 2313 are provided with a limiting rod 2314 that is fitted to the base 1 in the Z direction. The limiting rod 2314 is used to limit the lifting stroke of the lifting frame 231. The lifting plate 2311 is also provided with a guide block 235. The guide block 235 is provided with a guide slope that cooperates with the suction nozzle fixture 9 in the X direction.

[0073] The lifting plate 2311 is connected to the connecting rod plate 2313 via the guide shaft 2312, making the lifting frame 231 a whole. The guide shaft 2312 is guided and assembled with the base plate 11 of the base 1 along the Z direction, and the guide shaft 2312 guides the lifting and lowering of the lifting frame 231. In this embodiment, two sets of guide shafts 2312 are arranged at intervals along the Y direction. The two sets of guide shafts 2312 can ensure the structural stability between the lifting plate 2311 and the connecting rod plate 2313. Linear bearings 8 are fitted on the outer side of both sets of guide shafts 2312. The linear bearings 8 are fixedly assembled on the base plate 11. The linear bearings 8 can further reduce the movement resistance of the guide shafts 2312.

[0074] The lifting cylinder 232 is fixedly mounted on the base plate 11. The bottom of the lifting plate 2311 is equipped with a floating joint 6. The lifting cylinder 232 is connected to the floating joint 6. The floating joint 6 can compensate for the positional displacement of the lifting cylinder 232 during lifting and extending the service life of the lifting module 23.

[0075] After the lifting module 23 is assembled on the base 1, the limiting rods 2314 on the lifting plate 2311 and the connecting rod plate 2313 are located on the upper and lower sides of the base plate 11, respectively. When the lifting cylinder 232 drives the lifting frame 231 to rise and fall, the limiting rods 2314 will abut against the base plate 11 to limit the lifting frame 231 to rise and fall. The Z-direction distance between the lifting plate 2311 and the limiting rods 2314 on the connecting rod plate 2313 is the lifting stroke of the lifting frame 231.

[0076] Guide blocks 235 are arranged on the lifting plate 2311. The guide slope of the guide block 235 engages with the nozzle insertion fixture 9 in the X direction. When the lifting frame 231 lifts the nozzle insertion fixture 9, the guide slope on the guide block 235 can engage with the side of the nozzle insertion fixture 9, making the lifting of the nozzle insertion fixture 9 stable. After the nozzle insertion fixture 9 is delivered to the coarse positioning module 21, the lifting module 23 rises, and the guide block 235 engages with the end faces of the nozzle insertion fixture 9 at both ends in the X direction, so that the nozzle insertion fixture 9 falls on the lifting plate 2311, and the lifting plate 2311 can lift the nozzle insertion fixture 9 to the required position.

[0077] Preferably, multiple sets of coarse positioning modules 21 are symmetrically arranged along the Y direction. The coarse positioning module 21 includes a support column 211 and a buffer block 212 arranged on the top of the support column 211. The buffer block 212 is provided with a guide slope that cooperates with the insertion nozzle tool 9 along the Y direction.

[0078] The coarse positioning module 21 is symmetrically arranged along the Y-axis. The guide slope on the buffer block 212 mates with the bottom of the two Y-axis end faces of the nozzle insertion fixture 9, guiding the nozzle insertion fixture 9 so that it falls onto the plane of the buffer block 212 under the action of the guide slope. The support column 211 and the buffer block 212 support the nozzle insertion fixture 9, preparing it for the lifting module 23 to lift the nozzle insertion fixture 9. The buffer block 212 is installed on the support column 211 to cushion the nozzle insertion fixture 9 and prevent damage from hard impacts.

[0079] Preferably, the blocking module 22 includes a blocking frame 221 arranged on the base 1, a blocking rubber pad 222 provided on the blocking frame 221, the blocking module 22 is movably assembled on the base 1 in the X direction, and the base 1 is also provided with a blocking block 223 that blocks the blocking module 22 in the X direction.

[0080] There is only one set of blocking modules 22, which is arranged on one side of the base plate 11 in the X direction, so that the nozzle insertion fixture 9 can be placed onto the positioning unit 2 from the side without the base plate 11 and without the blocking module 22. The blocking rubber pad 222 is arranged on the side of the blocking module 22 facing the coarse positioning module 21. When the nozzle insertion fixture 9 is placed on the coarse positioning module 21, the nozzle insertion fixture 9 contacts the blocking rubber pad 222, which can prevent the blocking frame 221 from making hard contact with the nozzle insertion fixture 9 and causing damage to the nozzle insertion fixture 9.

[0081] In this embodiment, the blocking frame 221 is formed of sheet metal and is movably mounted on the base plate 11 along the X-direction. When the blocking frame 221 moves on the base plate 11, it can buffer and absorb the force transmitted by the nozzle insertion fixture 9, thus protecting the nozzle insertion fixture 9. There are two sets of blocking blocks 223. One set of blocking blocks 223 is fixedly mounted on the base plate 11, and the other set of blocking blocks 223 is bolted to the blocking frame 221. The blocking frame 221 has a long groove extending along the X-direction, and one set of blocking blocks 223 is mounted in the long groove, which can adjust the position of the blocking frame 221.

[0082] Preferably, the Y-axis moving module 41 includes a linear module 411, a connecting shaft 412, and a fixing plate 413. The linear module 411 and the connecting shaft 412 both extend along the Y-axis and are spaced apart along the X-axis. One end of the fixing plate 413 is guided and assembled with the linear module 411, and the other end is guided and assembled with the connecting shaft 412. The Z-axis moving module 42 includes a Z-axis cylinder 421 fixedly assembled on the fixing plate 413. The Z-axis cylinder 421 is connected to the mounting base 51 in a driving connection. The mounting base 51 and the fixing plate 413 are guided and assembled along the Z-axis.

[0083] The Y-axis moving module 41 is formed by a linear module 411, a connecting shaft 412, and a fixing plate 413. The linear module 411 and the connecting shaft 412 are standard parts and are fixedly welded to the mounting bracket 12 of the base 1. One end of the fixing plate 413 is fixedly connected to the linear module 411, and the other end is guided and assembled to the connecting shaft 412 through a linear bearing 8. The linear module 411 can drive the fixing plate 413 to move along the Y-axis, thereby adjusting the position of the Z-axis moving module 42 on the fixing plate 413.

[0084] Z-axis cylinder 421 is fixedly mounted on fixed plate 413. Z-axis cylinder 421 is fixedly connected to floating joint 6 on top plate 511 of mounting base 51, thereby driving mounting base 51 to move along Z-axis. In this embodiment, linear bearing 8 is also arranged on fixed plate 413, and guide rod 422 is vertically arranged on top plate 511 of mounting base 51. Guide rod 422 is guided and assembled with linear bearing 8 on fixed plate 413. When Z-axis cylinder 421 drives mounting base 51 to rise and fall, the rising and falling direction of mounting base 51 can be limited by guide rod 422 and linear bearing 8, so that the lifting and falling of suction nozzle module 5 is stable and the resistance is reduced. There are two guide rods 422. The top ends of the two guide rods 422 are connected by plate to form a whole, so that the structure of guide rod 422 is stable.

[0085] The working process of this invention is as follows:

[0086] When it is necessary to feed the nozzle insertion fixture 9, the transport device sends the nozzle insertion fixture 9 into the feeding device. Under the action of the guide slope of the buffer pad, it is placed on the coarse positioning module 21 and supported by the support column 211 and the buffer pad of the coarse positioning module 21. The lifting cylinder 232 of the lifting module 23 drives the lifting frame 231 to move up and down. The positioning pin 233 and the nozzle insertion fixture 9 are inserted and matched to achieve precise positioning. After the lifting plate 2311 lifts the nozzle insertion fixture 9 to a certain height, the fine positioning sensor 234 is triggered, indicating that the nozzle insertion fixture 9 has moved to the set position.

[0087] The operator first feeds the nozzle into the vibratory feeder 31. The vibratory feeder 31 starts to transport the nozzle through vibration, sucking the material trough 34 of the common direct vibration feeder 32 to the material pick-up platform 33. After the sensor on the material pick-up platform 33 detects that the material trough 34 is full of nozzles, the Z-axis cylinder 421 of the Z-axis moving module 42 drives the nozzle clamping module 5 to move downward. Then, the drive cylinder 541 of the drive unit 54 drives the push plate 542 to extend. The push plate 542 pushes the spring shaft 5223 to move against the elastic force of the compression spring 523, causing the moving clamp 5222 to move away from the fixed clamp 5221. The half-groove opens to clamp the nozzle. After clamping the nozzle, the drive cylinder 541 drives the push plate 542 to retract. Under the action of the elastic force of the compression spring 523, the half-groove closes and clamps the fixed nozzle.

[0088] The Z-axis cylinder 421 of the Z-axis moving module 42 moves upward, driving the suction nozzle module 5 and the suction nozzle to move upward. The linear module 411 of the Y-axis moving module 41 works, driving the fixed plate 413 and the Z-axis moving module 42 to move along the Y direction, adjusting the Y-axis position of the suction nozzle module 5, so that the suction nozzle module 5 moves above the suction nozzle insertion fixture 9.

[0089] The motor 531 of the X-axis moving module 53 starts and drives the lead screw assembly 533 to rotate. Through the lead screw connecting block 534, the nozzle assembly 52 slides sequentially on the rail 513. Under the constraint of the connecting plate 7 and the connecting groove 71, each group of nozzle assemblies 52 begins to change pitch. After the pitch change is completed, the position of each group of nozzle assemblies 52 is the same as the nozzle assembly position on the nozzle insertion fixture 9. The Z-axis cylinder 421 of the Z-axis moving module 42 extends and drives the clamping nozzle module 5 to move downward. The drive cylinder 541 of the drive unit 54 drives the push plate 542 to move. The push plate 542 pushes the moving clamp 5222 to move through the spring shaft 5223. After the half groove opens, the nozzle is released and placed on the nozzle insertion fixture 9, completing the automatic nozzle feeding operation.

[0090] In summary, this invention provides an automatic nozzle feeding device. When it is necessary to feed the nozzle tooling, the operator can first arrange the nozzle tooling on the positioning unit, and the positioning unit positions the nozzle tooling. Then, the nozzles are placed in the vibrating plate. The vibrating plate uses vibration to spirally arrange the nozzles sequentially and feed them through a linear vibrating feeder. The linear vibrating feeder arranges the nozzles into a single straight line and conveys them to the material trough on the picking platform. Then, the Y-axis moving module and Z-axis moving module of the transfer unit cooperate to move the nozzle clamping module to the upper side of the picking platform. The drive unit drives the grippers to clamp the nozzles on the picking platform, and then the transfer unit moves the nozzle clamping module and the nozzles on it to the nozzle feeding platform. On the upper side of the nozzle fixture, the X-axis moving module drives each set of nozzle assemblies to move along the X-axis, so that each set of nozzle assemblies corresponds one-to-one with the nozzle assembly position on the nozzle insertion fixture. The drive unit drives the gripper to release the nozzle, thus assembling the nozzle into the nozzle insertion fixture. Through the cooperation of various structures, the nozzle can be accurately and automatically placed into the nozzle insertion fixture. The operator only needs to put the nozzle into the vibratory feeder, which reduces manual intervention in nozzle placement and labor costs, reduces the safety risks of the equipment to personnel, improves the efficiency of placing nozzles into the nozzle insertion fixture, realizes the automatic feeding function of the nozzle insertion fixture, meets the needs of large-scale production, and also leaves sufficient operating space for daily equipment maintenance.

[0091] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present invention, and these improvements and substitutions should also be considered within the scope of protection of the present invention.
