Description

Technical Field

[0001] This application relates to the field of electronic component manufacturing technology, and in particular to a material transfer mechanism. Background Technology

[0002] In the existing technology, in order to realize the material transfer and conveying action, three sets of guided bases are usually designed. With sliding motion, a power source is also required on each of the three sets of guided bases to drive the material transfer and conveying mechanism to complete the material transfer and conveying action.

[0003] like Figure 1 As shown, the existing material transfer and conveying mechanism 10' typically includes two up-and-down moving cylinders 100' and one material transfer and conveying cylinder 200'. The material transfer and conveying cylinder 200' is used to drive the material transfer claw to move back and forth, and the up-and-down moving cylinders 100' are used to drive the material transfer claw to move up and down, thereby completing the lifting and lowering and forward and backward movement of the material transfer claw, completing the material transfer process of "rising - moving forward to transfer material - moving downward to reset - moving backward to reset".

[0004] The aforementioned material conveying mechanism is relatively large, and the accumulated errors from the three drive systems during processing and assembly can reduce the accuracy of product conveying. Furthermore, the large size of the mechanism reduces its flexibility. The coordinated operation of the three power sources results in a long response time and low efficiency for the entire machine. Utility Model Content

[0005] The purpose of this application is to provide a material transfer mechanism to overcome the shortcomings of the prior art.

[0006] To achieve the above objectives, this application provides the following technical solution:

[0007] A material transfer mechanism includes: a first cam, a second cam, a rotating shaft, a rotating drive, a material transfer assembly, a lifting seat, and a swing arm; the rotating shaft is connected to the rotating drive, and the first cam and the second cam are both sleeved on the rotating shaft; the first cam is connected to the lifting seat to drive the lifting seat to rise and fall; the second cam is connected to the swing arm to drive the swing arm to swing back and forth, and the swing arm is connected to the material transfer assembly to drive the material transfer assembly to move back and forth; the lifting seat is located at both ends of the material transfer assembly, and the material transfer assembly is slidably connected to the lifting seat in the back-and-forth direction.

[0008] In some embodiments, the first cam has a limiting groove on one side along the front-rear direction, and the bottom end of the lifting seat has a limiting post, which is engaged in the limiting groove and can slide in the limiting groove.

[0009] The limiting groove has a base circle segment close to the center of the first cam and a protruding segment further away from the center of the first cam than the base circle segment;

[0010] When the first cam rotates to a position where the protruding section engages with the limiting post, the first cam lifts the lifting seat upwards; when the first cam rotates to a position where the base circle section engages with the limiting post, the first cam pulls the lifting seat downwards.

[0011] In some embodiments, the bottom end of the swing arm is rotatably connected to the machine base so that the swing arm can swing back and forth; the top end of the swing arm is connected to the material transfer assembly; two clamping posts are provided at the middle position of the swing arm, the two clamping posts are clamped on the wheel side of the second cam, and the second cam can slide between the two clamping posts;

[0012] The wheel rim of the second cam includes a forward portion and a rearward portion in the circumferential direction. When the second cam rotates to a position where the forward portion is located between the two clamping posts, the second cam can push the swing arm forward to push the material. When the second cam rotates to a position where the rearward portion is located between the two clamping posts, the second cam can push the swing arm backward to reset.

[0013] In some embodiments, there are two first cams, which are respectively located at both ends of the second cam in the front-rear direction, and the first cams are connected to the lifting seat in a one-to-one correspondence.

[0014] In some embodiments, the material transfer assembly includes a material transfer rod and a plurality of material transfer claws spaced apart on the material transfer rod in a front-to-back direction.

[0015] In some embodiments, the material transfer assembly further includes a connecting block disposed on the material transfer rod, the connecting block having a groove extending in the vertical direction; the top end of the swing arm has a sliding column, the sliding column being slidably engaged in the groove.

[0016] In some embodiments, the rotary drive is located on one side of the rotary shaft along the left-right direction, and the rotary drive is connected to the rotary shaft via a transmission component.

[0017] In some embodiments, the transmission component includes a first synchronous pulley, a second synchronous pulley, and a synchronous belt connected between the first synchronous pulley and the second synchronous pulley. The first synchronous pulley is connected to the output shaft of the rotary drive component, and the second synchronous pulley is sleeved on the rotary shaft.

[0018] In some embodiments, the material transfer device further includes a mounting base disposed on the machine base, and the swing arm is rotatably connected to the mounting base.

[0019] In some embodiments, the material transfer device further includes:

[0020] The conveying channel is composed of two halves, left and right, with the material to be moved supported between the two halves. The conveying channel is arranged above the material transfer rod, and the two halves are located on the left and right sides of the material transfer claw, respectively. There is a gap between the two halves. The material transfer claw can extend into the gap to push the material to be moved.

[0021] The advantages of this application are:

[0022] This application uses a first cam to drive the lifting seat to rise and fall, which in turn drives the material transfer assembly to rise and fall. A second cam and a swing arm drive the material transfer assembly to move back and forth, thus achieving the vertical and horizontal movement of the material transfer assembly and completing the material transfer operation. The first and second cams are mounted on the same rotating shaft and driven by the same rotary drive component, resulting in a simplified and compact overall structure with a small size. Furthermore, the reduced number of drives in the entire mechanism leads to smaller installation errors and higher conveying accuracy. Fewer drives also result in shorter response times and higher efficiency. Attached Figure Description

[0048] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0049] This application provides a material transfer mechanism. For example... Figure 2 As shown, the material transfer device 10 of this embodiment includes a first cam 100, a second cam 200, a rotating shaft 300, a rotating drive component 400, a material transfer assembly 500, a lifting seat 600, and a swing arm 700. It is understood that the entire material transfer mechanism needs to be mounted on a machine base (not shown in the figure). Specifically, as... Figure 3 As shown, the material 101 on the conveying channel 11 is pushed forward and fed by the material transfer component 500 of the material transfer device 10.

[0050] like Figure 2 and Figure 3 As shown, both the first cam 100 and the second cam 200 are mounted on the rotating shaft 300, and the first cam 100 and the second cam 200 are driven to rotate via the same rotating shaft 300. The rotating shaft 300 is connected to a rotary drive component 400. The rotary drive component 400 can be a motor, such as a servo motor, or other rotary drive mechanisms. Figure 3 As shown, the first cam 100 is connected to the lifting seat 600 to drive the lifting seat 600 to rise and fall. Since the material transfer assembly 500 is mounted on the lifting seat 600, when the lifting seat 600 rises and falls under the drive of the first cam 100, it can also drive the material transfer assembly 500 to rise and fall synchronously. The second cam 200 is connected to the swing arm 700 to drive the swing arm 700 to swing back and forth. The swing arm 700 is connected to the material transfer assembly 500 to drive the material transfer assembly 500 to move back and forth. The lifting seat 600 is mounted at both ends of the material transfer assembly 500, and the material transfer assembly is slidably connected to the lifting seat 600 in the front-back direction (X direction), so that the material transfer assembly can slide back and forth on the lifting seat 600 to complete the material transfer.

[0051] In summary, the lifting and forward / backward movement of the material transfer assembly 500 can be achieved through the first cam 100 and the second cam 200, thus completing the material transfer operation. The first cam 100 and the second cam 200 are mounted on the same rotating shaft 300 and driven by a single rotary drive component 400. The overall structure is simple and compact, with a small size. Furthermore, the fewer drives involved in the entire mechanism result in smaller installation errors and higher conveying accuracy. Fewer drives also lead to shorter response times and higher efficiency.

[0052] Specifically, such as Figure 6 and Figure 7As shown, the first cam 100 has a limiting groove 110 on one side along the front-rear direction (X direction), and the limiting groove 110 extends circumferentially around the first cam 100. Figure 8 and Figure 9 As shown, the bottom end of the lifting seat 600 is provided with a limiting post 610, which fits in the limiting groove 110 and can slide within the limiting groove 110. Figure 6 and Figure 7 As shown, the limiting groove 110 has a base circular segment 111 close to the center O of the first cam 100 and a protruding segment 112 further away from the center O of the first cam 100 than the base circular segment 111. Figure 9 As shown, when the first cam 100 rotates to the position where the protruding section 112 engages with the limiting post 610, the side wall of the protruding section 112 pushes the lifting seat 600 upward, that is, the first cam 100 lifts the lifting seat 600 upward, thus raising the lifting seat 600. Figure 8 As shown, when the first cam 100 rotates to the position where the base circle segment 111 engages with the limiting post 610, the inner wall of the base circle segment 111 pulls the lifting seat 600 downwards. In other words, the first cam 100 pulls the lifting seat 600 down, thus lowering the lifting seat 600. The structure of the first cam 100 described above enables the lifting seat 600 to rise and fall, and the lifting seat 600 drives the material transfer assembly 500 to rise and fall synchronously.

[0053] In the embodiments of this application, such as Figure 5 As shown, the bottom end of the swing arm 700 is rotatably connected to the machine base, allowing the swing arm 700 to swing back and forth. The top end of the swing arm 700 is connected to the material transfer assembly 500, so that when the swing arm 700 swings back and forth, it drives the material transfer assembly 500 to move back and forth. Figure 12 As shown, two clamping posts 710 are provided at the middle position of the swing arm 700. (As indicated...) Figure 5 As shown, two clamping posts 710 are clamped on the wheel edge 210 of the second cam 200, and the second cam 200 can slide between the two clamping posts 710, thereby avoiding clamping and interference with the rotation of the second cam 200.

[0054] like Figure 10 and Figure 11 As shown, the wheel edge 210 of the second cam 200 includes a forward portion 211 and a rearward portion 212 in the circumferential direction (X direction). It can be understood that, as... Figure 11 As shown, the front part 211 and the rear part 212 are connected by an arc segment, so that the wheel edge 210 of the second cam 200 is wavy when viewed from the side, which can realize the function of pushing the material assembly 500 back and forth.

[0055] Combination Figure 5 and Figure 11When the second cam 200 rotates to a position where the front portion 211 is positioned between the two clamping posts 710, the second cam 200 can push the swing arm 700 forward to push the material. When the second cam 200 rotates to a position where the rear portion 212 is positioned between the two clamping posts 710, the second cam 200 can push the swing arm 700 backward to reset. That is to say, during the rotation of the second cam 200, when the front portion 211 of the second cam 200 rotates to a position between the two clamping posts 710, it will push the swing arm 700 forward; when the rear portion 212 of the second cam 200 rotates to a position between the two clamping posts 710, it will pull the swing arm 700 backward, thereby causing the swing arm 700 to swing back and forth, and the swing arm 700 can drive the material transfer assembly 500 to move back and forth.

[0056] In the embodiments of this application, such as Figure 3 As shown, there are two first cams 100, which are respectively located at both ends of the second cam 200 in the front-rear direction (X direction), that is, at both ends of the rotating shaft 300. The second cam 200 is located at the middle position of the rotating pin 702. Figure 3 As shown, the first cam 100 is connected to the lifting seat 600 in a one-to-one correspondence. There are also two lifting seats 600, which are respectively set at both ends of the material transfer assembly 500.

[0057] In the embodiments of this application, such as Figure 13 As shown, the material transfer assembly 500 includes a material transfer rod 510 and material transfer claws 520. Multiple material transfer claws 520 are arranged at intervals along the material transfer rod 510 in the front-to-back direction (X direction). Having multiple material transfer claws 520 allows for the simultaneous movement of multiple materials 101.

[0058] like Figure 5 As shown, the material transfer assembly 500 also includes a connecting block 530, which is disposed on the material transfer rod 510 and is used to connect the swing arm 700. Figure 5 As shown, the connecting block 530 is provided with a slide groove 531 extending in the vertical direction. It can be understood that the slide groove 531 is located on the side of the connecting block 530 near the swing arm 700 to facilitate connection of the swing arm 700 via the slide groove 531. Figure 12 As shown, a sliding post 720 is provided at the top of the swing arm 700. (As indicated...) Figure 5 As shown, the sliding column 720 is slidably fitted in the sliding groove 531. Due to the fit between the sliding column 720 and the sliding groove 531, and because the material transfer assembly 500 is slidably mounted on the lifting seat 600, the swing arm 700 can drive the material transfer assembly 500 to move back and forth when it swings back and forth.

[0059] In this embodiment, the limiting post 610 at the bottom of the support base, the clamping post 710 on the swing arm 700, and the sliding post 720 at the top of the swing arm 700 all employ cam bearing followers. Of course, in other optional embodiments, other cylindrical structures may also be used.

[0060] like Figure 3 As shown, the rotary drive 400 is disposed on one side of the rotary shaft 300 along the left-right direction (Y direction), and the rotary drive 400 is connected to the rotary shaft 300 via the transmission component 800. By disposing the rotary drive 400 on one side of the rotary shaft 300 and connecting it via the intermediate transmission component 800, compared to directly connecting one end of the rotary shaft 300 to the rotating shaft of the rotary drive 400, the overall size of the material transfer mechanism along the front-back direction (X direction) can be shortened.

[0061] In one embodiment, such as Figure 2 As shown, the transmission component 800 includes a first synchronous pulley 810, a second synchronous pulley 820, and a synchronous belt 830. The synchronous belt 830 connects the first synchronous pulley 810 and the second synchronous pulley 820. The first synchronous pulley 810 is connected to the output shaft of the rotary drive component 400. In this embodiment, the rotary drive component 400 is a motor. Therefore, as... Figure 2 As shown, the output shaft of the rotary drive 400 is the rotor of the motor, and the first synchronous pulley 810 is connected to the rotor of the motor. The second synchronous pulley 820 is sleeved on the rotary shaft 300. The rotary drive 400 transmits torque to the first synchronous pulley 810, which drives the second synchronous pulley 820 through the synchronous belt 830. The second synchronous pulley 820 transmits torque to the rotary shaft 300, thereby causing the rotary shaft 300 to drive the first cam 100 and the second cam 200 on it to rotate.

[0062] refer to Figure 2 The material transfer device 10 also includes a mounting base 701. The mounting base 701 is mounted on the machine base. The swing arm 700 is rotatably connected to the mounting base 701. Figure 2 and Figure 12 The swing arm 700 is rotatably connected to the mounting base 701 via the rotating pin 702.

[0063] like Figure 5 As shown, the material transfer device 10 also includes a conveying channel 11. The conveying channel 11 is composed of two halves of the channel 11a, one on the left and one on the right. Figure 5 Only half is shown. The material to be moved 101 is supported between the left and right halves of the flow channel 11a. (Reference) Figure 4 The left side of the material to be moved 101 is supported on the left side of the flow channel 11a, and the right side of the material to be moved 101 is supported on the other half of the flow channel 11a (not shown). The material transfer claw 520 is inserted from the bottom between the two halves of the flow channel 11a to move the material to be moved 101. Specifically, as shown... Figure 5 As shown, the conveying channel 11 is arranged above the transfer rod 510, and the two half channels 11a are located on the left and right sides of the transfer claw 520, respectively. There is a gap between the two half channels 11a, and the transfer claw 520 can penetrate into the gap to push the material 101 to be moved.

[0064] The working process of the material transfer mechanism in this embodiment is as follows:

[0065] Material 101 enters the conveyor channel 11;

[0066] Rotating shaft 300 rotates, causing first cam 100 to rotate to the position where the protruding section 112 of the upper limit groove 110 of first cam 100 engages with the limiting post 610 at the bottom of lifting seat 600, thereby enabling first cam 100 to push lifting seat 600 upward, lifting seat 600 and material transfer assembly 500 rise together and be raised to the predetermined position.

[0067] The rotating shaft 300 continues to rotate, causing the second cam 200 to rotate until the front part 211 of the wheel edge 210 of the second cam 200 enters the position between the two clamping posts 710 of the swing arm 700, so that the second cam 200 can push the swing arm 700 to swing forward, and the swing arm 700 drives the material transfer assembly 500 to move forward, thereby pushing the material 101 forward.

[0068] The rotating shaft 300 continues to rotate, causing the first cam 100 to rotate to the position where the base circle segment 111 of the upper limit groove 110 of the first cam 100 engages with the limiting post 610 at the bottom of the lifting seat 600, thereby enabling the first cam 100 to pull the lifting seat 600 downward, and the lifting seat 600 drives the material transfer assembly 500 to descend together and reset to the initial height;

[0069] The rotating shaft 300 continues to rotate, causing the second cam 200 to rotate until the rear part 212 of the wheel edge 210 of the second cam 200 enters the position between the two clamping posts 710 of the swing arm 700. This allows the second cam 200 to pull the swing arm 700 to swing backward, and the swing arm 700 drives the material transfer assembly 500 to move backward to reset, waiting for the next material pushing operation.

[0070] The technical features in the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0071] The embodiments described above merely illustrate the implementation methods of this application, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
