Description

Technical Field

[0001] This utility model relates to the field of screw fastening machines, specifically to a blow-suction type screw fastening machine. Background Technology

[0002] Existing automatic screw fastening equipment is generally divided into two types: air-blowing and air-suction. Air-blowing screw fastening equipment operates by blowing screws through a supply pipe into the screw clamp via an air feeder, then a cylinder drives the electric screwdriver downwards to fasten the screws. Air-suction screw fastening equipment operates by using a telescopic mechanism to drive a screw sleeve up and down. The sleeve mechanism has a vacuum connector on its side wall, and a servo screw drives a suction head to pick up the screw at the screw feeding point, then moves it to the product fastening point for fastening. In extensive customer use, it has been found that air-blowing chucks are unusable in situations with special fastening locations, such as when the space for fastening is narrow or when there is a significant height difference between the product and the fastening location. Air-suction chucks are suitable for relatively small screws, generally below M3. When customers require larger screws and demand air-suction, existing chucks cannot meet their needs.

[0003] To simultaneously achieve both blowing and suction functions, as exemplified by patent CN219074845U, entitled "A Blowing and Suction Screw Locking Mechanism," a control panel and a guide rail are included. The guide rail is fixed to the control panel, and a front slider and a rear slider are mounted on the guide rail. A suction nozzle assembly is fixed to the front slider. The drawback is that under external force, the screw is prone to slipping or falling off during clamping and conveying, leading to inaccurate locking and affecting product quality. Utility Model Content

[0004] In view of the shortcomings of the existing blow-suction type screw fastening machine in terms of unstable clamping, the purpose of this utility model is to provide a blow-suction type screw fastening machine that increases the stability of clamping and effectively prevents the screw from slipping or falling off during clamping and conveying.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a blow-suction type screw fastening machine, comprising:

[0006] Fixed base;

[0007] An electric screwdriver, wherein the electric screwdriver is equipped with a screwdriver bit;

[0008] A suction rod, wherein a first channel is provided inside the suction rod, and the bit passes through the first channel;

[0009] The clamping assembly includes a clamping seat, a clamping mouth that can open and reset, and a supply port for connecting to a supply tube. The clamping seat is provided with two side plates, and an elastic element is provided between the two side plates. The length direction of the elastic element is perpendicular to the length direction of the first channel.

[0010] In this technical solution, the elastic element between the two side plates on the clamp holder provides cushioning and adaptability when the clamp is subjected to external forces, thus maintaining a stable clamping force and effectively improving the stability of screw clamping, preventing screws from slipping or falling off during conveying and fastening. Simultaneously, the channel design within the suction rod ensures precise guidance of the screw by the bit, making the entire screw-fastening process smoother and more efficient, significantly improving the automation level and operational efficiency of the production line. Through automated feeding, precise guidance, and stable clamping design, the efficiency of screw fastening is greatly improved, and the production cycle is shortened.

[0011] This invention is further configured such that: the clamping nozzle seat is provided with a second channel and a feeding channel, the first channel, the second channel and the feeding channel are interconnected, and the clamping nozzle is connected to the second channel. The clamping nozzle seat of the blow-suction type screw fastening machine is provided with a second channel and a feeding channel, and the first channel, the second channel and the feeding channel are all interconnected. The connection between the clamping nozzle and the second channel ensures that screws or other fasteners can smoothly enter the second channel through the feeding channel and ultimately be precisely tightened by the clamping nozzle. This not only improves the efficiency and accuracy of screw fastening but also makes the entire machine's workflow smoother and more reliable.

[0026] The present invention will be further described below with reference to the accompanying drawings.

[0027] Example 1:

[0028] Reference Figures 1 to 3 A blow-suction type screw fastening machine, comprising:

[0029] Fixture 1;

[0030] Electric screwdriver 2, wherein the electric screwdriver 2 is provided with a screwdriver bit 21;

[0031] The suction rod 3 has a first channel 31 inside, and the bit 21 passes through the first channel 31.

[0032] The clamping assembly 4 includes a clamping seat 41, a clamping mouth 42 capable of opening and resetting, and a supply port 43 for connecting to a supply tube.

[0033] The clamp seat 41 is provided with two side plates 44, and an elastic element 45 is provided between the two side plates 44. The length direction of the elastic element 45 is perpendicular to the length direction of the first channel 31.

[0034] In this embodiment, the elastic element 45 between the two side plates 44 on the clamping jaw seat 41 provides the clamping jaw 42 with a certain degree of buffering and adaptability when subjected to external forces, thereby maintaining a stable clamping force and effectively improving the stability of screw clamping, preventing the screw from slipping or falling off during the conveying and fastening process.

Through automated feeding, precise guidance, and stable clamping design, the efficiency of screw fastening is greatly improved, and the production cycle is shortened.

[0035] Preferably, the elastic element 45 is a spring.

[0036] refer to Figure 3The clamping nozzle seat 41 is provided with a second channel 46 and a feeding channel 47. The first channel 31, the second channel 46, and the feeding channel 47 are interconnected, and the clamping nozzle 42 is connected to the second channel 46. The clamping nozzle seat 41 of the blow-suction type screw fastening machine is provided with a second channel 46 and a feeding channel 47, and the first channel 31, the second channel 46, and the feeding channel 47 are all interconnected. The clamping nozzle 42 is connected to the second channel 46, ensuring that screws or other fasteners can smoothly enter the second channel 46 through the feeding channel 47 and finally be precisely tightened by the clamping nozzle 42. This not only improves the efficiency and accuracy of screw fastening but also makes the entire machine's workflow smoother and more reliable.

[0037] The blow-suction type screw fastening machine also includes a first drive component 5 and a second drive component 6, which are respectively disposed on both sides of the electric screwdriver 2. The first drive component 5 and the second drive component 6 are disposed on the left and right sides of the electric screwdriver 2, forming a cooperative working layout, which enhances the stability and functionality of the equipment.

[0038] In one embodiment of this utility model, the electric screwdriver 2 is slidably connected to the fixed base 1 via a first mounting plate, the suction rod 3 is slidably connected to the fixed base 1 via a second mounting plate 7, and the clamping assembly 4 is fixedly connected to the fixed base 1 via a third mounting plate.

Furthermore, the clamping assembly 4 is firmly fixed to the fixed base 1 via the third mounting plate, providing stable support and precise positioning for the entire screw-locking process.

[0039] In one embodiment of this utility model, a guide rail 11 is fixed on the fixed base 1, and a front slider 12 and a rear slider 13 are provided on the guide rail 11. The clamping nozzle assembly 4 is fixed on the front slider 12, and the electric screwdriver 2 is fixed on the rear slider 13. The front slider 12 and the rear slider 13 on the guide rail 11 of the fixed base 1 of the blow-suction screw fastening machine can move smoothly along the guide rail 11, providing a precise and stable motion trajectory for each component of the equipment. In particular, the clamping nozzle assembly 4 is firmly fixed on the front slider 12, so that the clamping nozzle 42 can be positioned to clamp the screw as the front slider 12 moves, ensuring the stability of the screw during the conveying and fastening process. At the same time, the electric screwdriver 2 is fixed on the rear slider 13, and the movement of the rear slider 13 drives the precise displacement of the electric screwdriver 2, so that the screwdriver bit 21 can accurately align with the screw for tightening operation.

[0040] In another embodiment of this utility model, the fixed base 1 is provided with connecting holes, which are connected to the suction assembly. Through these connecting holes, the screw fastening machine can easily and tightly connect with the suction assembly, thus forming an efficient and collaborative working system. The connection of the suction assembly enables the screw fastening machine to quickly and accurately pick up and position screws during operation, greatly improving the automation level and efficiency of the work. At the same time, this connection method also ensures stable transmission between the suction assembly and the screw fastening machine, avoiding the loss or misalignment of screws during transport, further improving the reliability and accuracy of the equipment.

[0041] Preferably, one end of the suction rod 3 is provided with a sealing ring to seal one end opening of the first channel 31. The sealing ring tightly wraps around one end opening of the first channel 31 of the suction rod 3, achieving a seal on the opening. This not only effectively prevents the intrusion of external air or impurities, ensuring the purity and stability of the screw during suction and transmission, but also greatly improves the working efficiency and accuracy of the screw fastening machine.

The locking cylinder, with its efficient locking capability and stable output force, ensures that the screw is securely locked in the designated position. This drive component design not only improves the operating efficiency and accuracy of the screw fastening machine but also enhances its overall stability and durability. Simultaneously, the coordinated work of the extension cylinder and the locking cylinder allows the blow-suction type screw fastening machine to demonstrate superior performance and potential in the field of automated assembly.

[0044] Understandably, when the extension cylinder is in the retracted state and the locking cylinder is in the extended state, the screw is blown to the clamp 42 position; when the extension cylinder is in the retracted state and the locking cylinder changes from extended to retracted, the clamp 42 picks up the screw; the electric screwdriver 2 changes from retracted to extended, completing the screw locking.

[0045] Understandably, the clamping nozzle 42 clamps and positions the screw, and the air-blowing feeder stops feeding air. Then, the suction rod 3 moves towards the screw, and the suction assembly connects sequentially with the mounting hole, the first through hole, and the first channel 31. Therefore, under the negative pressure generated by the suction assembly, the screw can be attracted to the end of the suction rod 3. Next, the suction rod 3 continues to move downward, passing through the clamping nozzle 42, and reaches the product fastening position. Finally, the electric screwdriver 2 moves downward and starts to complete the screw fastening.

[0046] The above description of the specific embodiments of this utility model is only used to further illustrate this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-essential improvements and adjustments made to this utility model by technical engineers based on the above description of the utility model shall fall within the scope of protection of this utility model.
