Description

Technical Field

[0001] This utility model belongs to the field of industrial gear technology, and in particular relates to an anti-tilting micro gear feeding mechanism. Background Technology

[0002] In the current industrial gear manufacturing field, especially in the high-precision automated assembly and loading of micro gears, how to achieve efficient, directional, and non-destructive continuous transport and stacking of micro workpieces has always been a key challenge restricting production efficiency and quality.

[0003] Traditional micro gear feeding methods often use a combination of vibratory feeders and linear feeders or robotic arms for gripping. While this can achieve a certain degree of automation, it has significant limitations: First, micro gears are small in size and light in weight, and are prone to tilting, flipping, or even jamming during transport due to vibration or airflow. When gears need to enter the stacking station in a specific posture (such as vertical), existing devices often lack effective posture correction and holding mechanisms, resulting in poor stability of the gears during transfer, which in turn leads to stacking misalignment and jamming. Utility Model Content

[0004] The purpose of this invention is to provide an anti-tilting micro gear feeding mechanism, which aims to solve the technical problem that micro gears are prone to tilting when entering the stacking station in the prior art.

[0005] To achieve the above objectives, this utility model provides an anti-tilting micro gear feeding mechanism for feeding and batch stacking micro gears, including a frame with a front opening, and... The feeding unit includes a feeding component, which is flush with the upper end of the frame and extends outward from the frame; the feeding component has a through feeding port; The stacking unit includes a buffer component disposed within the frame and movable back and forth. The buffer component has a communicating arc groove with an upper opening. The front end of the buffer component has a swing unit. The communicating arc groove, the swing unit, and the feeding component cooperate to form a connecting channel. The connecting channel has a left connecting port and a right connecting port that are connected end to end. The buffer component is positioned at its forward limit and at its rear limit. A pushing unit is located on the left side of the frame, and the driving end of the pushing unit passes through the left connecting port and enters the communicating arc groove; An upper top unit is disposed below the buffer component. The driving end of the upper top unit passes through the connecting arc groove from bottom to top and extends into the connecting channel to divide it into a first buffer cavity and a second buffer cavity. The feeding port is directly opposite the first buffer cavity. The first buffer cavity can just fall into the micro gear to keep it in a vertical state. The swing unit has its inner side abutting against the feeding component; the swing unit remains open when the buffer component moves to the rear position to open the communication arc groove and the pushing unit; the swing unit remains retracted when the buffer component moves to the front position to open the communication arc groove and the feeding port.

[0006] Furthermore, the connecting arc groove forms a concave semi-circular arc shape facing downwards, and its diameter is adapted to the diameter of the micro gear; at the same time, the front and rear width of the feeding port is adapted to the diameter of the connecting arc groove, so that the micro gear can just pass through the feeding port and reach the connecting arc groove.

[0007] Furthermore, the swing unit includes a deflection block and a connecting shaft. The front end of the buffer is rotatably connected to the lower end of the deflection block through the connecting shaft. A torsion spring is also sleeved on the connecting shaft. The torsion spring is connected to the deflection block and the connecting shaft, so that the deflection block and the buffer remain in a contracted state without interference.

[0008] Furthermore, a supporting top plate is provided on the side of the feeding component near the buffer component, and the front end of the supporting top plate abuts against the deflection block; wherein, when the buffer component moves to the rear position, the lower end of the deflection block moves backward with the buffer component, and the upper end of the deflection block always abuts against the supporting top plate, so that the buffer cavity is aligned with the communication of the pushing unit; when the buffer component moves to the front position, the lower end of the deflection block moves forward with the buffer component, and the upper end of the deflection block always abuts against the supporting top plate, so that the buffer cavity opens and communicates with the feeding port.

[0009] Furthermore, the deflection block has a clearance position on the side near the buffer.

[0010] Furthermore, the pushing unit includes a top extension member and left and right top extension cylinders. The left and right top extension cylinders are provided at the left end of the frame. The driving end of the left and right top extension cylinders drives the top extension member to extend from left to right into the connecting channel to place the micro gear from the first buffer cavity into the second buffer cavity.

[0011] Furthermore, the upper lifting unit includes an upper lifting cylinder, a fixed sleeve, and an upper lifting member. The upper lifting cylinder is connected to the lower end of the buffer member through the fixed sleeve. The driving end of the upper lifting cylinder is connected to the upper lifting member. The upper lifting member passes through the fixed sleeve and penetrates the buffer member to divide the connection channel into the first buffer cavity and the second buffer cavity.

[0012] Furthermore, a front-to-back translation cylinder is provided inside the frame. The driving end of the front-to-back translation cylinder is connected to a drive block, and the other end of the drive block is connected to the buffer component to drive the buffer component to move back and forth.

[0013] Furthermore, the deflection block has a clearance position on the side near the buffer.

[0014] Furthermore, a detection unit is provided on one side of the frame. The detection unit includes a detection motion cylinder, a detection bracket, and a detection sensor. The detection motion cylinder is installed on one side of the frame. The drive end of the detection motion cylinder is connected to the detection bracket, and one end of the detection bracket is connected to the detection sensor to drive the sensor to move closer to or away from the second buffer cavity.

[0015] The anti-tilting micro gear feeding mechanism provided in this embodiment of the utility model has at least one of the following technical effects: In this design, a movable buffer unit within the frame, along with its internal connecting arc groove, cleverly cooperates with the feeding unit and the swing unit to form a connecting channel with specific left and right connection ports. Combined with the coordinated action of the pushing unit and the top unit, the driving end of the top unit extending into the channel divides the internal space into first and second buffer chambers. This ensures that the micro-gear remains vertical when it falls into the first buffer chamber directly opposite the feeding port, effectively preventing tilting and rolling during stacking. The swing unit automatically switches between open and retracted states based on the change in the buffer unit's position, connecting with the pushing unit or the feeding port respectively, achieving smooth gear transfer and continuous stacking, demonstrating significant practicality.

[0023] In one embodiment of this utility model, as shown in the appendix Figure 1 , 2 As shown, an anti-tilting micro gear feeding mechanism is used to feed and batch stack micro gears, including a frame 100 with a front opening, and... The feeding unit 110 includes a feeding component 120, which is flush with the upper end of the frame 100 and extends outward from the frame 100; the feeding component 120 is provided with a through feeding port 130. The stacking unit 200 includes a buffer 210 disposed within the frame 100 and movable back and forth. The buffer 210 has a connecting arc groove 220 with an upper opening. The front end of the buffer 210 is provided with a swing unit 500. The connecting arc groove 220, the swing unit 500, and the feeding component 120 cooperate to form a connecting channel 230. The connecting channel 230 has a left connecting port 240 and a right connecting port 250 that are connected end to end. The buffer 210 is moved to the forward limit position, which is set as the forward position 260. The buffer 210 is moved to the rear limit position, which is set as the rear position 270. A pushing unit 300 is located on the left side of the frame 100. The driving end of the pushing unit 300 passes through the left connection port 240 and enters the connecting arc groove 220. The upper top unit 400 is located below the buffer component 210. The driving end of the upper top unit 400 extends from bottom to top through the connecting arc groove 220 and into the connecting channel 230 to divide it into a first buffer cavity 211 and a second buffer cavity 212. The feeding port 130 is directly opposite the first buffer cavity 211. The first buffer cavity 211 can just fall into the micro gear to keep it in a vertical state. The swing unit 500 has its inner side abutting against the feeding component 120, so that the swing unit 500 remains open when the buffer component 210 moves to the rear position 270, so as to open the communication between the connecting arc groove 220 and the pushing unit 300; the swing unit 500 remains retracted when the buffer component 210 moves to the front position 260, so as to open the communication between the connecting arc groove 220 and the feeding port 130.

[0024] Specifically, the micro gears are fed one by one to the feeding port 130 of the feeding component 120, which is flush with the upper end of the frame 100. In the initial state of the mechanism, the buffer component 210 is in the front position 260, the swing unit 500 is in the retracted state, and the connecting arc groove 220 is connected to the feeding port 130. The buffer cavity and the upper push component 430 of the upper push unit 400 are in the raised state, and their driving end extends from top to bottom into the connecting channel 230, dividing the connecting arc groove 220 into the first buffer cavity 211 and the second buffer cavity 212. Under the action of the robot or manual operation, a micro gear falls vertically from the feeding port 130 into the first buffer cavity 211 directly below it. Since the front and rear width of the feeding port 130 is precisely matched with the diameter of the connecting arc groove 220, the gear can fall smoothly and maintain a stable vertical posture, completing the initial buffering of a single gear. Next, with the upper unit 400 in a descending state, and the buffer 210 moving to the connecting channel 230 and aligned horizontally with the pushing unit 300, the swing unit 500 is in an open state, contacting the loading component 120. The driving end of the pushing unit 300 extends from the left connecting port 240, horizontally passing through the first buffer cavity 211, and smoothly pushes the micro gear located therein into the second buffer cavity 212 on the right. After the push is completed, the pushing unit 300 resets, and the top extension 310 retracts to its original position, preparing for the next action.

[0025] This cycle repeats continuously. Each time, the pushing unit 300 pushes the newly dropped gear from the first buffer cavity 211 into the second buffer cavity 212, and then the remaining discharging mechanism removes the micro gear from the second buffer cavity 212. The buffer component 210 moves forward - the upper lifting component 430 descends - the gears fall and stack - the upper lifting component 430 rises - the buffer component 210 moves backward, realizing a continuous, stable, and tilt-resistant batch stacking operation of micro gears.

[0026] Furthermore, such as Figure 3As shown, the connecting arc groove 220 forms a concave semi-circular arc shape facing downwards, with its diameter matching the diameter of the micro gear. Simultaneously, the front-to-back width of the feed port 130 matches the diameter of the connecting arc groove 220, allowing the micro gear to pass precisely through the feed port 130 and reach the connecting arc groove 220. Specifically, because the front-to-back width of the feed port 130 matches the diameter of the connecting arc groove 220, the feed port 130 itself constitutes a narrow channel that guides the gear's posture, allowing a micro gear to pass only in a specific direction. After the gear passes through this precisely wide feed port 130, it falls directly into the semi-circular arc-shaped connecting arc groove 220, whose diameter matches its width. This downwardly concave semi-circular arc structure is the core component for achieving the "anti-tilt" function. After the gear falls in, its cylindrical outer wall naturally fits against the inner wall of the arc groove. Under the influence of gravity, the gear's axis automatically adjusts to be parallel to the axis of the arc groove, i.e., it becomes vertical. This fitted diameter ensures that the gear has no excess wobble space within the arc groove, and is precisely positioned and constrained in attitude. Subsequently, when the buffer unit 210 moves back and forth carrying the vertically positioned gear, or when the drive end of the upper unit 400 rises from below, this tight fit continues to function, ensuring that the gear remains vertical during movement and transfer, and does not tip over or jam due to any gaps.

[0027] Furthermore, such as Figure 4 , 5 As shown, the swing unit 500 includes a deflection block 510 and a connecting shaft 520. The front end of the buffer 210 is rotatably connected to the lower end of the deflection block 510 through the connecting shaft 520. A torsion spring 530 is also sleeved on the connecting shaft 520. The torsion spring 530 is connected to the deflection block 510 and the connecting shaft 520, so that the deflection block 510 and the buffer 210 remain in a contracted state without interference. A supporting top plate 140 is also provided on the side of the feeding component 120 near the buffer component 210. The front end of the supporting top plate 140 abuts against the deflection block 510. When the buffer component 210 moves to the rear position 270, the lower end of the deflection block 510 moves backward with the buffer component 210, while the upper end of the deflection block 510 remains in contact with the supporting top plate 140, aligning the buffer cavity with the push unit 300. When the buffer component 210 moves to the front position 260, the lower end of the deflection block 510 moves forward with the buffer component 210, while the upper end of the deflection block 510 remains in contact with the supporting top plate 140, opening the buffer cavity and connecting it with the feeding port 130. A clearance space 540 is provided on the side of the deflection block 510 near the buffer component 210.

[0028] Specifically, due to the action of the torsion spring 530, the deflection block 510 will continuously abut against the support top plate 140. When the buffer 210 needs to move from the rear position 270 to the front position 260 or vice versa, the deflection block 510, as a movable part at the front end of the buffer 210, moves along with it, and the upper end of the deflection block 510 will interact with the support top plate 140. 1. When the buffer 210 moves to the front position 260, the interaction between the deflection block 510 and the support top plate 140 causes it to deflect to another angle, thereby closing the path connected to the push unit 300 and opening the path connected to the feed port 130, forming a contracted state. The upper push unit 400 isolates the first buffer cavity 211 and the second buffer cavity 212. At this time, the micro gear can only enter the first buffer cavity 211 to wait. The contracted state limits the movement of the micro gear. 2. When the buffer 210 moves to the rear position 270, the upper end of the deflection block 510 contacts the support plate 140 during the movement. Since the support plate 140 is fixed, this forces the deflection block 510 to overcome the force of the torsion spring 530 and deflect around the connecting shaft 520, thereby opening the limit of the deflection block 510 on the micro gear. This allows the micro gear to connect the communicating arc groove 220 inside the buffer 210 with the direction from the push unit 300. This state is the "open state". Conversely, the torsion spring 530 plays a key role here in providing the reset torque and maintaining contact stability, ensuring that the deflection block 510 can switch between the two states in a timely and reliable manner.

[0029] Further details are attached. Figure 1 As shown, the pushing unit 300 includes a top extension member 310 and left and right top extension cylinders 320. The left end of the frame 100 is provided with left and right top extension cylinders 320. The driving end of the left and right top extension cylinders 320 drives the top extension member 310 to extend from left to right into the connecting channel 230 so as to push the micro gear from the first buffer cavity 211 into the second buffer cavity 212.

[0030] Further details are attached. Figure 1 As shown, the upper lifting unit 400 includes an upper lifting cylinder 410, a fixing sleeve 420, and an upper lifting member 430. The upper lifting cylinder 410 is connected to the lower end of the buffer member 210 through the fixing sleeve 420. The driving end of the upper lifting cylinder 410 is connected to the upper lifting member 430. The upper lifting member 430 passes through the fixing sleeve 420 and penetrates the buffer member 210 to divide the connection channel 230 into a first buffer cavity 211 and a second buffer cavity 212.

[0031] Further details are attached. Figure 2 As shown, a front-to-back translation cylinder 600 is provided inside the frame 100.

[0032] Further details are attached. Figure 1 As shown, a detection unit 700 is also provided on one side of the frame 100. The detection unit 700 includes a detection motion cylinder 710, a detection bracket 720, and a detection sensor 730. The detection motion cylinder 710 is installed on one side of the frame 100. The driving end of the detection motion cylinder 710 is connected to the detection bracket 720. One end of the detection bracket 720 is connected to the detection sensor 730 to drive the sensor to move closer to or away from the second buffer cavity 212.

[0033] Further details are attached. Figure 1 As shown, the bottom of the frame 100 is connected to a movable fixed base 800. Adjustable installation methods, such as through sliding rail linkage or interlocking, allow for quick adjustment of the working height of the feeding mechanism according to actual working conditions, ensuring that its feeding port 130 can perfectly connect with the feeding equipment.
