Description

Technical Field

[0001] This utility model belongs to the field of carbon fiber badminton racket manufacturing, and more specifically, it relates to a badminton racket feeding unit and a badminton racket grinding device. Background Technology

[0002] Carbon fiber badminton rackets consist of a head and a handle. Most of their core components are molded using molds. During injection molding or hot pressing, overflow, flash, and burrs are easily generated at the mold closing points. In particular, when carbon fiber composite materials are cured, the resin may overflow from the mold gaps due to pressure, resulting in rough surfaces and sharp edges on the badminton racket. This directly affects the product's texture and safety, so badminton rackets need to be polished.

[0003] In the process of polishing badminton rackets, the loading of rackets is a common process. The usual method is to manually load the rackets into a designated device, but this not only increases labor costs but also hinders the full utilization of the equipment. Another loading method is illustrated by patent CN218110372U, which discloses a fully automatic badminton racket polishing fixture. This fixture includes a racket input mechanism comprising a slide plate on which a racket collecting rack is mounted. The fixture body also features a racket lifting mechanism that cooperates with the racket collecting rack. During feeding, the badminton rackets are placed in the racket collecting rack, and a lead screw drives the mechanism to move it to the racket lifting mechanism position, where a robotic arm then picks them up. This method results in slow racket loading speeds, and the rackets are prone to misalignment when stacked, leading to poor accuracy.

[0004] Furthermore, patent CN208382794U discloses a badminton racket conveying device that is a mouth-shaped or O-shaped conveyor line viewed from above. A conveyor belt is set on the conveyor line, and multiple equally spaced slots are set on the conveyor belt. The slots are used to install badminton rackets or tennis rackets to be sprayed. A conveyor motor is set below the conveyor belt. The badminton rackets are only transported by the conveyor belt. The badminton rackets are prone to shaking, which makes it difficult for the next process to quickly and accurately identify the position of the racket handle, affecting the progress of the next process. Moreover, each badminton racket needs to be stuck in the slot, making the process complicated and affecting the efficiency of material loading.

[0005] The aforementioned feeding unit has low transmission efficiency for badminton rackets and poor positioning accuracy. Summary of the Invention

[0006] 1. The problem to be solved

[0007] In view of the problems of low transmission efficiency and poor positioning accuracy of existing feeding units for badminton rackets, the first aspect of this utility model provides a feeding unit for badminton rackets;

[0008] The second aspect of this utility model provides a badminton racket polishing device, which includes the aforementioned badminton racket feeding unit.

[0009] 2. Technical Solution

[0010] To solve the above problems, the present invention adopts the following technical solution.

[0011] The first aspect of this utility model provides a badminton racket feeding unit for feeding badminton rackets into a badminton racket polishing device, wherein the badminton racket includes a handle and a head disposed on the handle.

[0012] The feeding unit includes a conveying component and a guiding component.

[0013] The transmission component includes a transmission bracket and a transmission belt mounted on the transmission bracket. The racket head is mounted on the transmission belt for transmitting the badminton racket to the next unit.

[0014] The guiding component includes a guide groove located below the conveyor support, parallel to the conveyor belt, forming a channel for the paddle handle to pass through.

[0015] In one embodiment of this utility model, the transmission belt is driven by a power component, which includes a drive wheel and a driven wheel. The drive wheel and the driven wheel are respectively mounted on the conveyor bracket. The transmission belt is sleeved on the drive wheel and the driven wheel to realize the transmission of the transmission belt, thereby driving the transmission of badminton rackets. Through the action of the transmission belt, the badminton rackets enter the next station in sequence, making it less likely for them to stack.

[0016] In one embodiment of this utility model, the conveying bracket is provided with a support frame located between the driving wheel and the driven wheel. The support frame has a groove, and the transmission belt is driven in the groove of the support frame. By setting the support frame, the transmission belt is less likely to deform under the weight of multiple badminton rackets, reducing transmission resistance and improving transfer efficiency.

[0017] In one embodiment of this utility model, the end of the conveying bracket is provided with a side plate, which is respectively provided on both sides of the conveying bracket. The height of the side plate is higher than the height of the conveyor belt. When the racket head is transported to the end of the conveying bracket, it is blocked by the side plate to prevent the badminton racket from continuing forward after reaching the end of the conveying bracket, which would cause it to slip.

[0018] In one embodiment of this utility model, there are two baffles, which are arranged opposite to each other to form a channel through which the racket handle can pass.

[0019] The two baffles can be arranged in parallel or at a certain angle, as long as the handle can pass through.

[0020] In one embodiment of this utility model, the baffle is fixed to the surface of the lower frame by a support frame, and the support frame is equipped with a flipping motor to drive the baffle to flip. The flippable baffle can be one or two. When badminton rackets need to be mounted on the conveyor belt, flipping at least one baffle to a parallel state facilitates mounting multiple badminton rackets on the conveyor belt. When transporting badminton rackets using the conveyor belt, flipping the baffle creates a channel between the two baffles that allows the racket handle to pass through, preventing the handle from wobbling during transport and ensuring accurate gripping by the rotating jaws at the next station when transported to the designated position.

[0021] In one embodiment of this utility model, a baffle is provided at the end of the guide groove, which abuts against the handle to limit the position of the handle.

[0022] Preferably, when the handle stops at the position where it abuts against the baffle, it is the position where the rotating gripper of the next station can accurately grasp it, thus avoiding the need for the rotating gripper to adjust its position multiple times based on the position of the handle.

[0023] In one embodiment of this utility model, the lower end of the racket handle is lower than the lowest position of the stop bar, and the lower end of the racket handle extends out of the bottom of the guide groove. A photoelectric sensor is provided at the end of the guide groove to identify the position of the racket handle. When a racket handle is detected at the end of the guide groove, the operation of the transmission belt is stopped to prevent badminton rackets from stacking.

[0024] In one embodiment of this utility model, the contact position between the racket head and the side plate and the contact position between the racket handle and the baffle are on the same vertical plane, so that the racket head and the racket handle are in a vertical state on the conveying bracket. In this vertical state, the racket handle is not easy to shake when it is grasped.

[0025] The second aspect of this utility model is to provide a badminton racket polishing device, which includes the aforementioned badminton racket feeding unit. By feeding the badminton racket into the badminton racket polishing device and then moving it to the next working position, the feeding unit effectively improves the transfer speed and stability of the badminton racket, and ultimately improves the positioning accuracy.

[0026] 3. Beneficial effects

[0027] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0028] I. Badminton racket loading unit:

[0029] (1) The badminton racket feeding unit of this utility model puts the racket head on the conveyor belt and transports the badminton racket through the conveyor belt. At the same time, a guide groove is provided at the handle of the badminton racket to achieve stable transmission of the badminton racket and high positioning accuracy.

[0030] (2) The badminton racket feeding unit of this utility model has a guide groove composed of a flip-up baffle. When it is necessary to feed the badminton racket onto the conveyor belt, the baffle is flipped to the horizontal direction, so that the feeding side is empty, which facilitates the concentrated feeding of the badminton racket; when the badminton racket is transported by the conveyor belt, the baffle is flipped to the vertical direction to form a guide groove parallel to the conveyor belt, which prevents the badminton racket from shaking and resulting in poor transport efficiency.

[0031] (3) The badminton racket feeding unit of this utility model has a side plate at the end of the conveyor bracket that is higher than the conveyor belt for limiting the racket head, and a baffle at the end of the guide groove for limiting the racket handle to prevent the badminton racket from falling. It can also improve the positioning accuracy of the badminton racket and facilitate the subsequent gripping of the racket handle.

[0032] (4) The badminton racket feeding unit of this utility model is equipped with a photoelectric sensor at the end of the guide groove to identify the racket handle extending from the bottom of the guide groove. When the photoelectric sensor identifies that the racket handle has reached the end of the guide groove, the transmission belt stops rotating to prevent the badminton rackets from accumulating at the end of the transmission belt.

[0033] II. Badminton racket polishing device:

[0034] (5) The badminton racket grinding device of this utility model can realize the automatic feeding of multiple badminton rackets through the above-mentioned feeding unit, realize the smooth feeding from the feeding unit to the next working position, and the badminton rackets are not easy to fall during the process, the positioning accuracy is high, and the transmission efficiency of badminton rackets is effectively improved.

[0047] The following detailed description and exemplary embodiments of the present invention can be better understood in conjunction with the accompanying drawings, wherein the elements and features of the present invention are identified by reference numerals.

[0048] Example 1

[0049] In badminton racket production, the efficiency of material loading determines the production rate. Traditional manual loading suffers from low efficiency and low production line utilization. Existing automatic loading devices cannot guarantee the stability of racket transmission and the accuracy of final positioning, resulting in inefficient integration with subsequent processes and affecting transfer efficiency. Therefore, this application utilizes the structure of the badminton racket to effectively improve loading efficiency by guiding and limiting the racket head (a) and handle (b), while ensuring transmission stability and final positioning accuracy.

[0050] The badminton racket includes a handle b and a head a disposed on the handle b. The head a is formed by the racket frame, forming a structure in which the head a can be hung.

[0051] The badminton racket loading unit of this embodiment is used for loading badminton rackets containing the aforementioned handle b and head a structure. The loading unit is as follows: Figure 1 As shown, it includes:

[0052] Transmission component 100 is used to transmit badminton rackets to the next working position;

[0053] The guide component 200 forms a channel through which the racket handle b passes, preventing the badminton racket from shifting position.

[0054] The transmission component 100, as Figure 3 As shown, the assembly includes: a conveyor bracket 110 fixedly mounted on a bracket of a badminton racket grinding device, and a transmission belt 120 disposed on the conveyor bracket 110. The head a of the badminton racket is fitted onto the transmission belt 120 for conveying the badminton racket to the next working position. The transmission belt 120 is driven by a power assembly, which includes a drive wheel 130 and a driven wheel 140. The drive wheel 130 and driven wheel 140 are respectively disposed at both ends of the conveyor bracket 110. The transmission belt 120 is fitted onto the drive wheel 130 and driven wheel 140. A motor drives the drive wheel 130 to rotate, which in turn drives the transmission belt 120 and driven wheel 140 to rotate, thus enabling the badminton racket to rotate on the transmission belt 120. Through this transmission assembly 100, multiple badminton rackets can be simultaneously hung on the transmission belt 120, and the transmission belt 120 can sequentially move the badminton rackets to the next working position, ensuring the orderly progress of production steps, saving labor costs, and realizing automatic badminton racket feeding.

[0055] Since badminton rackets have a certain mass, to prevent the conveyor belt 120 from deforming severely under the weight of the racket, a support frame 150 is provided on the conveyor bracket 110 to support the conveyor belt 120. The support frame 150 is located between the driving wheel 130 and the driven wheel 140. In this embodiment, the support frame 150 is as follows: Figure 4 As shown, the irregular part has a groove 151 on its surface. The transmission belt 120 is driven in the groove 151 of the support frame 150. When multiple badminton rackets are hung on the transmission belt 120, the support frame 150 bears the weight, which not only avoids serious deformation of the transmission belt 120, but also saves transmission power.

[0056] To prevent the badminton racket from falling off the end of the conveyor bracket 110 due to delayed transfer to the next working station when it reaches the end of the conveyor bracket 110, a side plate 160 is provided at the end of the conveyor bracket 110. Preferably, the side plate 160 is located on both sides of the driven wheel 140 at the end of the conveyor bracket 110, and the height of the side plate 160 is higher than the height of the transmission belt 120, so that the badminton racket is blocked from sliding down when it is conveyed to the end of the conveyor bracket 110. Furthermore, the width of the side plate 160 is greater than the width of the driven wheel 140, so that there is a certain gap between the racket head a and the driven wheel 140, preventing interference between the driven wheel 140 and the racket head a.

[0057] The guide component 200, as shown Figure 5 As shown, it includes a guide groove 210 located below the conveying bracket 110 (e.g., Figure 6The guide groove 210 is parallel to the transmission belt 120 and forms a channel for the racket handle b to pass through. The guide groove 210 is formed by baffles 220. Preferably, there are two baffles 220, which are arranged in parallel in this embodiment to form a channel for the racket handle b to pass through.

[0058] In this embodiment, at least one baffle 220 is a flip-up baffle 220. In one possible implementation, there are two baffles 220. One baffle 220 is fixed to the support surface of the badminton racket grinding device by a support frame 230, and the support frame 230 of the other baffle 220 is provided with a flip motor 240 to drive the baffle 220 to flip.

[0059] When badminton rackets need to be loaded onto the conveyor belt 120, the baffle 220 is flipped to the horizontal direction, making the loading side free and facilitating the concentrated loading of badminton rackets; when the badminton rackets are transported using the conveyor belt 120, the baffle 220 is flipped to the vertical direction, forming a guide groove 210 parallel to the conveyor belt 120, preventing the racket handle b from shaking, which would make it difficult for the next station to accurately grasp the racket.

[0060] A baffle 250 is provided at the end of the guide groove 210. When the badminton racket reaches the end of the conveyor belt 120, the racket head a abuts against the side plate 160, and the racket handle b abuts against the baffle 250. In this embodiment, the baffle 250 is located at the end of the fixedly connected stop bar 220. Through the cooperation of the side plate 160 of the conveyor bracket 110 and the baffle 250 at the end of the guide groove 210, the badminton racket is limited, preventing it from falling. In addition, since the positions of the side plate 160 and the baffle 250 are fixed, the stopping position of the badminton racket is also relatively fixed, which is beneficial for the gripping of the next working position without the need to readjust the position of the gripping component.

[0061] Preferably, the contact positions of the racket head a and the side plate 160 and the contact positions of the racket handle b and the baffle 250 are on the same vertical plane, so that the racket head a and the racket handle b are on the same vertical line on the conveying bracket 110, such as... Figure 2 As shown, the badminton racket is in a vertical position. On the one hand, the vertical position of the badminton racket facilitates the use of space, allowing for the sequential loading of a larger number of rackets. On the other hand, a vertical racket handle is easier to grip than a racket handle at any angle.

[0062] A photoelectric sensor 260 is provided at the end of the guide groove 210 to identify the position of the lower end of the racket handle b. The lower end of the racket handle b is below the lowest position of the stop bar 220 and extends beyond the bottom of the guide groove 210. The purpose is to stop the transmission belt 120 from rotating when the photoelectric sensor 260 detects the presence of the racket handle b at the end of the guide groove 210, preventing badminton rackets from accumulating at the end of the transmission belt 120; and to drive the transmission belt 120 to continue transporting the badminton rackets when the photoelectric sensor 260 detects the absence of the racket handle b at the end of the guide groove 210, i.e., when no badminton rackets are at the end of the guide groove 210.

[0063] The badminton racket feeding unit of this application places the racket head (a) onto a conveyor belt (120) for transporting the rackets. A guide groove (210) is provided at the racket handle (b) to ensure stable transport of the rackets, allowing multiple rackets to be fed sequentially. Furthermore, to prevent rackets from falling, blocking elements are provided at the ends of the conveyor bracket (110) and the guide groove (210). Even further, to prevent rackets from piling up at the end, a photoelectric sensor (260) is provided at the handle (b) to identify whether rackets are occupied or empty, controlling the stop or start of the conveyor belt (120) to achieve orderly feeding of multiple rackets.

[0064] In the loading process of a badminton racket, the flip motor 240 is first driven to flip the baffle 220 in the guide assembly 200 to a horizontal state. Then, the racket head a is fitted onto the conveyor belt 120 of the conveyor bracket 110. The flip motor 240 is driven to flip the baffle 220 to a vertical state, and the conveyor belt 120 is driven to transport the badminton racket to the end of the conveyor bracket 110. Under the action of the side plate 160 and the baffle 220, the badminton racket stops at the end of the conveyor bracket 110. The photoelectric sensor 260 senses the racket handle b at the end of the conveyor bracket 110 and stops the conveyor belt 120. After the badminton racket is transferred to the next working position, the photoelectric sensor 260 senses that the end of the conveyor bracket 110 is idle and then drives the conveyor belt 120 again.

[0065] Example 2

[0066] In this embodiment, the baffles 220 in the guide assembly 200 are non-parallel baffles 220, forming a channel that allows the racket handle b to pass through. For example, the two baffles 220 are at a certain angle, and they include a contracting end and a separating end. Preferably, the contracting end of the racket handle b corresponds to the end of the transmission belt 120, so that the racket handle b gradually tends to stabilize along the guide groove 210, avoiding the badminton racket from shaking on the transmission belt 120, which would prevent the racket handle b from being accurately grasped by the next station.

[0067] The "end of the transmission belt 120", "end of the conveyor bracket 110", or "end of the guide groove 210" mentioned here refers to the end along the walking direction of the badminton racket.

[0068] The “contracted end of the baffle 220” mentioned here refers to the end of the two baffles 220 that are close to each other;

[0069] The "separated end of the baffle 220" mentioned here refers to the end where the two baffles 220 are open to each other;

[0070] Preferably, the constricted ends of the baffles 220 are aligned, and the minimum width between the baffles 220 must be greater than the width of the badminton racket handle b, so as to ensure that the handle b can pass smoothly through the guide groove 210.

[0074] Head polishing unit: used for polishing position a of the badminton racket head;

[0075] Feeding unit: Used to collect badminton rackets;

[0076] The feeding unit and the handle grinding unit are transferred through the first transport unit. The grippers of the first transport unit are used to grip the handle b in the feeding unit and transfer it to the handle grinding unit.

[0077] The handle polishing unit and the head polishing unit are transferred through the second transport unit. The grippers of the second transport unit are used to grip the handle b in the handle b polishing unit and transfer it to the head polishing unit.

[0078] The head grinding unit and the unloading unit are transferred through the second transport unit. The grippers of the second transport unit are used to grip the handle b in the head grinding unit and transfer it to the unloading unit.

[0079] In this unit, the badminton racket at the end of the conveying bracket 110 is in a vertical position. The gripper in the first conveying unit grabs the vertical racket handle b and transfers the badminton racket to the racket handle polishing unit.
