Description

Technical Field

[0001] This utility model relates to the field of loudspeaker processing technology, specifically to an anti-misalignment structure for an automatic cassette loading machine for loudspeaker components. Background Technology

[0002] In automated assembly lines for speaker components, the reel loading machine is a key piece of equipment for the precise gripping and placement of parts such as the speaker frame. Traditional reel loading machines mostly rely on suction cups at the end of the gripper arm for adsorption and positioning. However, in actual operation, slight deviations in the position of incoming parts or lateral shifts during the lowering of the robotic arm often cause the suction cups to fail to accurately align with the center of the speaker frame. This leads to problems such as unstable adsorption, misplacement, or even parts falling and being damaged, seriously affecting production cycle and product consistency. Although existing technologies attempt to correct these issues through visual positioning or mechanical limits, the structures are often complex, the adjustments are not flexible enough, or they cannot dynamically adapt to and actively correct the positional deviation of the speaker frame during the gripping process. Utility Model Content

[0003] The purpose of this utility model is to address the defects and shortcomings of the existing technology by providing a reasonable and easy-to-use anti-misalignment structure for an automatic horn component loading machine, which can effectively solve the defects of the existing technology.

[0004] To achieve the above objectives, this utility model adopts the following technical solution: it includes a mounting plate, which is sleeved on the gripper rod of the tray loading machine, and the suction cup on the gripper rod of the tray loading machine is exposed on the lower side of the mounting plate; it also includes:

[0005] The anti-misalignment plate consists of four plates, which are equally angled and positioned on the lower side of the mounting plate. The plates are spliced ​​together in a conical shape. The upper side of the anti-misalignment plate is inclined toward the center of the mounting plate. A fixing plate is provided on the upper side of the outer wall of the anti-misalignment plate, and the fixing plate abuts against the lower surface of the mounting plate.

[0006] The sliding block consists of four blocks, each fixed to the upper surface of the mounting plate. One side of each sliding block is inclined toward the center point of the mounting plate, and the sliding block is slidably disposed in the sliding groove at the bottom of the mounting plate.

[0007] The abutting mechanism is mounted on the fixed plate and connected to four fixed plates.

[0008] With the above technical solution, the mounting plate is fixed to the gripper rod of the tray loading machine. When the gripper rod moves to one side of the speaker frame, the anti-misalignment plate abuts against the outside of the frame. During the contact process, the frame is positioned in the middle of the four anti-misalignment plates. When the gripper rod continues to move downward, the mounting plate drives the anti-misalignment plates downward. During the downward movement, the anti-misalignment plates are pushed. During the movement of the anti-misalignment plates, the sliding block moves along the inclined sliding groove, so that the axis of the anti-misalignment plates remains unchanged during the movement of the multiple anti-misalignment plates. Under the action of the contact mechanism, the frame is ensured not to be misaligned.

[0009] As a further improvement of this utility model, the abutment mechanism includes:

[0010] The insert rods are two in number and are symmetrically arranged on the lower side of the mounting plate and in the corresponding fixing plates at the front and back. The two ends of the insert rods are exposed on the outer side of the fixing plates.

[0011] The connecting plates consist of four plates, which are symmetrically fixed to both ends of the insertion rod in pairs. Each connecting plate has a movable block fixed to its upper side, and the movable block is slidably disposed in the groove at the bottom of the mounting plate.

[0012] The four contact springs are embedded and fixed in the opposite side wall of the two symmetrical moving blocks. The other end of the contact spring is fixed to the inner wall of the slide groove at the bottom of the mounting plate.

[0013] With the above technical solution, when the anti-misalignment plate comes into contact with the basin frame, the fixing plate drives the insertion rod to move. During the movement, the sliding block on the fixing plate moves along the sliding groove. At this time, the fixing plate slides on the insertion rod, which causes the moving block and the connecting plate to move outward, so that the contact spring is compressed. Through the action of the contact spring, the anti-misalignment plate and the basin frame are kept in contact.

[0014] As a further improvement of this utility model, guide rods are symmetrically fixedly arranged in the mounting plate, with the two ends of the guide rods passing through the corresponding moving blocks and the abutment springs on both sides, respectively; this facilitates the support of the abutment springs without affecting the movement of the moving blocks.

[0015] As a further improvement of this utility model, a spiral tube is screwed onto the top wall of the mounting plate via a bearing, and the spiral tube is screwed onto the gripper rod via a thread; this facilitates the connection between the mounting plate and the gripper rod, and at the same time, the height of the suction cup on the lower side of the gripper rod can be adjusted according to the height of the basin frame.

[0016] As a further improvement of this utility model, a limit rod is screwed onto the spiral tube, and an abutment pad is fixed to the inner end of the limit rod. The abutment pad is set to abut against the gripper rod.

[0017] With the above technical solution, after the mounting plate is installed on the gripper rod, the limiting rod is rotated until the contact pad at the inner end of the limiting rod contacts the gripper rod, thereby preventing the spiral tube from rotating.

[0018] As a further improvement of this utility model, two connecting rods are symmetrically fixed on the outer ring wall of the anti-misalignment plate. The connecting rods are inserted into the corresponding fixed plates. A limit frame is set inside the fixed plate. The limit frame is set in an inverted "L" shape. The horizontal plate of the limit frame is inserted into the limit groove on the corresponding connecting rod. Connecting springs are fixed on both sides of one side wall of the vertical plate of the limit frame. The connecting springs are fixedly connected to the inside of the fixed plate. The protrusion at the bottom of the vertical plate of the limit frame is movably set in the rectangular groove on the bottom wall of the fixed plate.

[0019] With the above technical solution, when the anti-misalignment plate needs to be replaced, the hand simultaneously pinches the vertical plate of the limiting frame inside the same fixed plate and moves it towards the center, so that the limiting frame separates from the connecting rod, thereby removing the anti-misalignment plate from the fixed plate for easy replacement.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows: The anti-misalignment structure of the automatic tray loading machine for speaker components described in this utility model, by setting a dynamically retractable conical anti-misalignment plate and an inclined sliding mechanism, can automatically guide the tray frame position during the gripping process, effectively preventing misalignment during adsorption and placement. The ingenious structure improves the stability and accuracy of assembly. This utility model has the advantages of reasonable design and low manufacturing cost. Attached Figure Description

Detailed Implementation

[0027] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. The preferred embodiments described are only examples. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0028] Example 1:

[0029] like Figures 1-4 As shown, this embodiment includes a mounting plate 1, which is sleeved on the gripper rod 2 of the tray loading machine, with the suction cup on the gripper rod 2 protruding from the lower side of the mounting plate 1. A spiral tube 8 is screwed onto the top wall of the mounting plate 1 via a bearing. The spiral tube 8 is threaded onto the gripper rod 2, facilitating the connection between the mounting plate 1 and the gripper rod 2, and allowing adjustment of the height of the suction cup on the lower side of the gripper rod 2 according to the height of the tray rack. A limiting rod 9 is threaded onto the spiral tube 8, and an abutment pad is fixed to the inner end of the limiting rod 9. The abutment pad engages with the gripper rod 2, and after the mounting plate 1 is installed onto the gripper rod 2, the limiting rod 9 is rotated until the abutment pad at the inner end of the limiting rod 9 abuts against the gripper rod 2, thereby preventing the spiral tube 8 from rotating. It also includes:

[0030] The anti-misalignment plate 3 consists of four plates, which are arranged at equal angles on the lower side of the mounting plate 1. The anti-misalignment plates 3 are spliced ​​together in a conical shape. The upper side of the anti-misalignment plate 3 is inclined towards the center of the mounting plate 1. A fixing plate 4 is provided on the upper side of the outer wall of the anti-misalignment plate 3. The fixing plate 4 is in contact with the lower surface of the mounting plate 1.

[0031] Two connecting rods 10 are symmetrically welded and fixed on the outer ring wall of the anti-misalignment plate 3. The connecting rods 10 are inserted into the corresponding fixed plate 4. The fixed plate 4 is provided with a limit frame 11. The limit frame 11 is arranged in an inverted "L" shape. The horizontal plate of the limit frame 11 is inserted into the limit groove on the corresponding connecting rod 10. Connecting springs 12 are welded and fixed on both sides of the vertical plate side wall of the limit frame 11. The connecting springs 12 are welded and fixed to the inside of the fixed plate 4. The protrusion at the bottom of the vertical plate of the limit frame 11 is movably arranged in the rectangular groove on the bottom wall of the fixed plate 4.

[0032] Sliding blocks 5, there are four sliding blocks 5, and they are welded and fixed to the upper surface of the fixing plate 4 one by one. One side of the sliding block 5 is inclined towards the center point of the mounting plate 1, and the sliding block 5 is slidably disposed in the sliding groove at the bottom of the mounting plate 1.

[0033] The contact mechanism 6 is mounted on the fixed plate 4 and is connected to the four fixed plates 4.

[0034] Example 2:

[0035] See Figure 1-2As shown, based on Embodiment 1, the abutment mechanism 6 includes:

[0036] Insert rod 6-1, there are two insert rods 6-1, and they are symmetrically arranged on the lower side of the mounting plate 1 and in the corresponding fixing plates 4. The two ends of the insert rod 6-1 are exposed on the outer side of the fixing plate 4.

[0037] There are four connecting plates 6-2, and they are fixed symmetrically in pairs to both ends of the insert rod 6-1. Each connecting plate 6-2 has a movable block 6-3 welded and fixed to its upper side. The movable block 6-3 is slidably set in the groove at the bottom of the mounting plate 1.

[0038] Four abutment springs 6-4 are embedded and welded to the opposite side walls of two symmetrical moving blocks 6-3. The other end of the abutment spring 6-4 is welded to the inner wall of the groove at the bottom of the mounting plate 1. Guide rods 7 are symmetrically welded and fixed inside the mounting plate 1. The two ends of the guide rods 7 pass through the corresponding moving blocks 6-3 and abutment springs 6-4 on both sides, which can facilitate the support of abutment springs 6-4 without affecting the movement of moving blocks 6-3.

[0039] When using this utility model, first fix the mounting plate 1 on the gripper rod 2 of the tray loading machine. When the gripper rod 2 moves toward the side of the speaker frame, the anti-misalignment plate 3 first contacts the outside of the frame and automatically adjusts the position of the frame during the contact process so that it is in the center area of ​​the four anti-misalignment plates 3. Then the gripper rod 2 continues to move down, and the anti-misalignment plate 3 is driven down together by the mounting plate 1.

[0040] During the downward movement, the anti-misalignment plate 3 is pushed, and the sliding block 5 on it moves along the inclined sliding groove, so that each anti-misalignment plate 3 maintains a stable axial position during the movement. When the anti-misalignment plate 3 is completely in contact with the basin frame, the fixing plate 4 drives the insertion rod 6-1 to move. At this time, the sliding block 5 on the fixing plate 4 moves along the sliding groove, and the fixing plate 4 slides along the insertion rod 6-1 at the same time, pushing the moving block 6-3 and the connecting plate 6-2 to move outward, compressing the contact spring 6-4. Through the restoring force of the spring, it is ensured that the anti-misalignment plate 3 is always in close contact with the basin frame, effectively preventing the basin frame from misaligning during operation.

[0041] When it is necessary to replace the anti-misalignment plate 3, pinch the vertical plates of the two limit frames 11 inside the same fixed plate 4 at the same time and press them towards the center to disengage the limit frame 11 from the connecting rod 10, so that the anti-misalignment plate 3 can be removed from the fixed plate 4 for quick replacement.

[0042] Compared with the prior art, the beneficial effects of this specific embodiment are as follows:

[0043] 1. By setting up a conical anti-misalignment plate 3 structure that can automatically center, the position of the speaker frame can be guided and corrected when gripping it, ensuring that the frame is always in the gripping center, effectively avoiding installation misalignment caused by offset, and improving the accuracy of tray positioning and production yield.

[0044] 2. The radial adjustment mechanism of sliding block 5 and inclined sliding groove is adopted so that the anti-misalignment plate 3 can be synchronously retracted inward during the pressing process to maintain the stability of the axis. This not only achieves flexible clamping of the basin frame, but also prevents workpiece damage caused by hard collision, thus taking into account both positioning reliability and operational safety.

[0045] 3. Through the spring force in the contact mechanism 6, the anti-misalignment plate 3 can adapt to the outer contour of the basin frame of different sizes and continuously apply uniform lateral constraint force, effectively suppressing the sliding or twisting of the basin frame during the movement of the robot arm, ensuring the stability and repeatability of the handling process.

[0046] 4. The modular anti-misalignment plate 3 design, combined with the convenient plug-in limiting structure, facilitates the quick replacement of guide components of corresponding specifications according to product specifications, significantly shortens the changeover and debugging time, improves the flexible production capacity of the equipment, and reduces maintenance complexity and spare parts costs.

[0047] For those skilled in the art, modifications can be made to the technical solutions described in the foregoing embodiments, and equivalent substitutions can be made to some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
