Description

Technical Field

The coating is attached to the transfer cutter wheels, and the two transfer cutter wheels are connected to a power device through a belt group for driving. When the fastener is placed between the two transfer cutter wheels, it can contact the surface of the fastener and apply the coating.

[0004] However, since the two transfer cutter wheels are driven by connecting to the power device through a belt, the belt is prone to gear misalignment and skipping teeth, as well as wear and breakage of the belt itself, and the transmission efficiency is relatively poor. In addition, due to the different sizes of the fasteners, in order to more accurately apply the coating to a specific position on the fastener, it is often necessary for the operator to perform alignment adjustment. The adjustment working hours are long, and the coating position must be adjusted based on experience, resulting in large differences in coating quality.

Detailed implementation manners

[0047] Please refer to Figure 1 and Figure 2 The present utility model provides an electric multi-axis precision transfer and gluing device, which is installed on a frame (not shown in the figure) and is used for coating on a fastener A, and has a fixed seat 10, a power group 20, a transfer group 30, an opening and closing electric adjustment group 40, and a position electric adjustment group 50.

[0048] Please refer to Figures 3 to 5。The power unit 20 is installed on the fixed seat 10 and has a driving motor 21, two driving wheels 22, and two universal couplings 23. The driving motor 21 is fixed on the fixed seat 10 and has a driving output shaft. One of the driving wheels 22 is connected to the driving output shaft of the driving motor 21, and the two driving wheels 22 are meshed with each other. Thus, when the driving motor 21 is driven, the two driving wheels 22 can be driven to rotate. One end of each universal coupling 23 is respectively connected to one of the driving wheels 22 and can rotate with the rotation of the driving wheel 22.

[0049] Please refer to Figure 5 and Figure 6 。The transfer unit 30 is installed on the fixed seat 10 and has two shaft seats 31, two transfer cutter wheels 32, and a gap. Each shaft seat 31 is connected to the other end of one of the universal couplings 23 that is not connected to the driving wheel 22 and has a rotating shaft 311. The rotating shaft 311 passes through the shaft seat 31, is connected to the universal coupling 23, and can rotate with the rotation of the universal coupling 23. In other words, both ends of each universal coupling 23 are respectively connected to one of the driving wheels 22 and one of the rotating shafts 311.

[0050] Each transfer cutter wheel 32 is connected to the end of one of the rotating shafts 311 and can rotate with the rotation of the rotating shaft 311. In other words, both ends of each rotating shaft 311 are respectively connected to one of the universal couplings 23 and one of the transfer cutter wheels 32. Thus, when the driving motor 21 is driven, it can sequentially drive the driving output shaft, the two driving wheels 22, the two universal couplings 23, the two rotating shafts 311, and the two transfer cutter wheels 32 to rotate, and each component is axially connected or meshed with each other without using a belt for connection.

[0051] The gap is located between the two transfer cutter wheels 32, and the fastener A can be accommodated in the gap and contact the two transfer cutter wheels 32. In this embodiment, each transfer cutter wheel 32 is a disk body. Since the outer peripheral surface of the disk body is thinner, it can more accurately coat the paint on a specific position of the fastener A. However, in other embodiments, the shape of the transfer cutter wheel 32 is not limited thereto.

[0052] Please refer to Figure 7 and Figure 8 。The opening and closing electric adjustment group 40 is connected to the two shaft seats 31 and can control the distance between the two shaft seats 31, thereby controlling the size of the gap between the two transfer cutter wheels 32. The opening and closing electric adjustment group 40 has a slide rail 41, two sliders 42, an opening and closing motor 43, two connecting blocks 44, and an opening and closing adjustment screw 45.

[0053] In the first embodiment (such as Figure 7As shown in the figure, the slide rail 41 is disposed on the fixed base 10. Two sliders 42 are disposed on the slide rail 41, and each slider 42 is connected to one of the shaft seats 31. The opening and closing motor 43 is preferably a servo motor or a stepper motor, and is connected to the two sliders 42, and can control the two sliders 42 to move on the slide rail 41. Thereby, the slider 42 can slide on the slide rail 41, and can drive the shaft seat 31 to move to control the gap size between the two transfer cutter wheels, so as to adjust according to various sizes of fasteners.

[0054] In the second embodiment (as Figure 8 shown in the figure), the opening and closing motor 43 further has an opening and closing output shaft (not shown in the figure). Each slider 42A is respectively connected to one of the shaft seats 31 via one of the connecting blocks 44, and each connecting block 44 has a threaded hole. The threaded hole is parallel to the moving direction of the slide rail 41A, and the thread directions of the threaded holes of the two connecting blocks 44 are different. The opening and closing adjustment screw 45 is disposed through the threaded holes of the two connecting blocks 44, and the opening and closing adjustment screw 45 has two threaded segments. The two threaded segments can respectively engage with the threaded holes of the two connecting blocks 44, and the two threaded segments are provided with threads of different thread directions. Thereby, when the opening and closing adjustment screw 45 rotates, the two connecting blocks 44 will move in different directions. The opening and closing output shaft of the opening and closing motor 43 is connected to one end of the opening and closing adjustment screw 45, and the opening and closing motor 43 can control the opening and closing adjustment screw 45 to rotate. In the second embodiment, the opening and closing electric adjustment group 40A is that the opening and closing motor 43 drives the opening and closing adjustment screw 45 to drive the connecting block 44 and the slider 42A to move, and then drives the shaft seat 31 to open and close. In other embodiments, the opening and closing electric adjustment group 40 may not be driven by the opening and closing adjustment screw 45, as long as the opening and closing of the slider 42 can be controlled.

[0055] Please refer to Figure 9 . The position electric adjustment group 50 is installed on the fixed base 10, and has a position adjustment motor 51, a moving member 52, a position adjustment screw 53, and an adjustment member 54. The position adjustment motor 51 is preferably a servo motor or a stepper motor, and is installed on the frame, and has a position adjustment output shaft (not shown in the figure). The position adjustment output shaft of the position adjustment motor 51 is parallel to the two rotating shafts 311 of the transfer group 30. The moving member 52 is fixed on the fixed base 10, and is connected to the position adjustment output shaft of the position adjustment motor 51. The moving member 52 can be controlled by the position adjustment motor 51 to move along the axial direction of the position adjustment output shaft, and the fixed base 10 and the transfer group 30 move along with the moving member 52. Thereby, the fixed base 10 and the transfer group 30 can move along the axial direction of the rotating shaft 311.

[0056] The position adjustment screw 53 is connected to the position adjustment output shaft of the position adjustment motor 51, and the position adjustment screw 53 can rotate with the rotation of the position adjustment output shaft. Moreover, the position adjustment screw 53 is parallel to the two rotating shafts 311 of the transfer unit 30. In other embodiments, a universal coupling 23 can also be connected between the position adjustment screw 53 and the position adjustment output shaft of the position adjustment motor 51, so that the position of the position adjustment screw 53 can be adjusted as required. The position adjustment screw 53 is disposed through the adjustment member 54, and the moving member 52 is connected to the adjustment member 54. The adjustment member 54 can move with the rotation of the position adjustment screw 53, thereby moving the moving member 52. In this embodiment, the position electric adjustment group 50 drives the adjustment member 54 and the moving member 52 to move by controlling the rotation of the position adjustment screw 53, and further drives the fixed seat 10 and the transfer unit 30 to move along the axial direction of the rotating shaft 311. In other embodiments, the position electric adjustment group 50 may not have the position adjustment screw 53 and the adjustment member 54, as long as it can drive the fixed seat 10 and the transfer unit 30 to move along the axial direction of the rotating shaft 311.

[0057] When coating with the fastener A, the conveying path of the fastener A needs to be set in the gap of the transfer unit 30 first, and the two transfer cutter wheels 32 are adjusted by the position adjustment screw 53 to align with the position where the fastener A is to be coated. Then, the opening and closing electric adjustment group 40 is adjusted so that the two transfer cutter wheels 32 can fit on the fastener A. The coating adheres to the transfer cutter wheels 32. After the driving motor 21 is started, the driving motor 21 sequentially drives the driving wheel 22, the universal coupling 23, the rotating shaft 311, and the transfer cutter wheels 32 to rotate, thereby coating the coating on the fastener A.

[0058] The advantages of the present utility model are that the driving of the transfer cutter wheel 32 is directly driven by a power device, without using a belt to connect the power device for driving, so as to improve the disadvantages of the belt being prone to tooth skipping, wear, and breakage. In addition, the opening and closing electric adjustment group 40 and the position electric adjustment group 50 are also added, and the opening and closing electric adjustment group 40 and the position electric adjustment group 50 can be controlled by a computer to adjust the position and opening and closing of the transfer cutter wheel 32, without manually adjusting the position of the transfer cutter wheel 32.
