Description

Technical Field

[0001] This utility model relates to the field of correction equipment technology, specifically to a welding strip correction assembly structure. Background Technology

[0002] The existing equipment employs a dual-cylinder linkage design, independently controlling the vertical lifting and horizontal clamping movements of the tail clamp. After the silicon wafer is precisely positioned, the coordinated action of these two cylinders enables precise offset correction of the solder strip at the tail of the wafer, ensuring accurate alignment with the welding position of adjacent wafers. The system components include key parts such as a hydraulic buffer device, a precision speed control valve, and position sensors. These parts not only require fine parameter adjustments but also present complex replacement challenges during routine maintenance. Furthermore, pressure fluctuations in the pneumatic system cause significant variations in cylinder response speed, directly impacting the overall equipment's operating cycle time and production efficiency. This inconsistency is particularly pronounced during prolonged continuous operation, further affecting the consistency of welded product quality, resulting in a high failure rate and significant inconvenience.

[0030] To make the technical solution of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] Example 1

[0032] Combined with appendix Figure 1-6 A welding strip correction assembly structure includes a mounting bracket 1, which includes a side plate and a bottom plate. The bottom plate is fixedly installed on the bottom of the side plate and is used to form a stable support structure for the side plate, thereby enabling the relevant components to be installed on the side plate.

[0033] A motor is fixedly mounted on the side plate, and a conjugate cam 6 is fixedly mounted on the motor's output shaft. The conjugate cam 6 is a coaxial double-layer cam, where the minimum wheel diameter of the cam closer to the motor is larger than the maximum wheel diameter of the cam farther from the motor. This results in one cam being significantly larger than the other. The cam closer to the motor with the larger wheel diameter is named the main cam 7, and the cam farther from the motor with the smaller wheel diameter is named the return cam 8. Both the main cam 7 and the return cam 8 are synchronously driven by the motor's output shaft, causing them to rotate at the same angular velocity. The significant difference in wheel diameter between the main cam 7 and the return cam 8 facilitates independent operation of the driven components of the main cam 7 and the return cam 8, preventing them from interfering with each other.

[0034] An opening can be provided on the side plate at the location where the conjugate cam 6 is set, so that the conjugate cam 6 can be directly exposed, making it convenient to observe the conjugate cam 6 directly, and also convenient to repair and maintain the conjugate cam 6.

[0035] A first driving plate 2 that slides vertically is installed on the side plate. The side plate and the first driving plate 2 are connected by a vertical slider and a vertical slide rail. This not only allows the side plate to slide vertically up and down, but also helps to correct deviation. A vertical slide rail is fixed on either side of the side plate and the first driving plate 2, and a vertical slider that slides with the vertical slide rail is fixed on the other side. A first top wheel mounting block 3 is provided at the bottom of the first driving plate 2. A first top wheel 4 is rotatably mounted at the bottom of the first top wheel mounting block 3. The first top wheel 4 abuts against the main cam 7 of the conjugate cam 6. The first top wheel 4 can move up and down to different degrees when the main cam 7 rotates. Thus, when the first top wheel 4 is driven up and down by the main cam 7, the first top wheel 4 synchronously drives the first driving plate 2 to move up and down through the first top wheel mounting block 3.

[0036] A lowering spring 5 is also provided between the second driving plate and the side plate. The lowering spring 5 can keep the first driving plate 2 moving downward, so that the first rotating top wheel 4 on the first driving plate 2 keeps in contact with the main cam 7, so that the main cam 7 can control the lifting and lowering of the first driving plate 2.

[0037] A transverse slide rail 9 is provided on the upper side of the first driving plate 2. A first transverse slider 10 and a second transverse slider 11 are slidably mounted on the transverse slide rail 9. The first transverse slider 10 and the second transverse slider 11 slide independently on the transverse slide rail 9. A first adapter strip 22 is fixedly installed on the top of the first transverse slider 10, and a second adapter strip 23 is fixedly installed on the second transverse slider 11. The first adapter strip 22 is provided with a plurality of equidistant and evenly distributed first paddles 12, and the second adapter strip 23 is also provided with a plurality of equidistant and evenly distributed second paddles 12. 3. The first adapter bar 22 and the second adapter bar 23 are overlapped in the axial direction of the conjugate cam 6. The first paddle 12 on the first adapter bar 22 and the second paddle 13 on the second adapter bar 23 are arranged in a cross pattern, so that the first paddle 12 and the second paddle 13 correspond one-to-one. When the corresponding first paddle 12 and the second paddle 13 are close to each other, the first paddle 12 and the second paddle 13 achieve the clamping function. When the first paddle 12 and the second paddle 13 are far apart from each other, the first paddle 12 and the second paddle 13 achieve the opening function.

[0038] To achieve the clamping and opening functions of the first paddle 12 and the second paddle 13, it is preferable that the first paddle 12 extends to the position of the second paddle 13, so that the first paddle 12 and the second paddle 13 have a partially overlapping area, thereby achieving the clamping and opening functions of the first paddle 12 and the second paddle 13.

[0039] The first adapter bar 22 and the second adapter bar 23 can be respectively provided with support sliders on the transverse slide rail 9. The support sliders cooperate with the first transverse slider 10 or the second transverse slider 11 to provide support for the first adapter bar 22 and the second adapter bar 23. The first transverse slider 10 and the second transverse slider 11 move towards each other, thereby clamping the first lever 12 and the second lever 13 through the first adapter bar 22 and the second adapter bar 23. The first transverse slider 10 and the second transverse slider 11 move away from each other, thereby opening the first lever 12 and the second lever 13 through the first adapter bar 22 and the second adapter bar 23.

[0040] The bottom of the first horizontal slider 10 is provided with a first control wheel 16, and the bottom of the second horizontal slider 11 is provided with a second control wheel 17. By moving the first control wheel 16 and the second control wheel 17 in opposite directions, the clamping and opening functions of the first paddle 12 and the second paddle 13 can be realized.

[0041] A vertical control slide rail 14 is fixedly installed on the upper side of the first top wheel 4 on the first driving plate 2. A control slider 15 slides on the vertical control slide rail 14 and moves up and down on the vertical control slide rail 14. A first control wheel 16 and a second control wheel 17 are respectively provided on the top two sides of the control slider 15. The bottom of the first horizontal slider 10 and the second horizontal slider 11 are provided with symmetrical control ears 18. The side of the symmetrical control ears 18 facing away from each other is a sloping structure. The side of the control ears 18 facing away from each other is inclined inward from top to bottom. The first control wheel 16 and the second control wheel 17 are located outside the control ears 18 of the first horizontal slider 10 and the second horizontal slider 11. The first control wheel 16 abuts against the inclined surface of the connecting ear on the same side, and the second control wheel 17 abuts against the inclined surface of the connecting ear on the same side. Thus, when the control slider 15 rises, the connecting ears on both sides bring the first control wheel 16 and the second control wheel 17 closer to each other through the inclined surfaces of the opposite sides, further bringing the first adapter bar 22 and the second adapter bar 23 closer to each other, thereby bringing the first paddle 12 and the second paddle 13 closer to each other.

[0042] Both sides of the first horizontal slider 10 and the second horizontal slider 11 are provided with horizontal springs 19. The elastic force of the horizontal springs 19 causes the first horizontal slider 10 and the second horizontal slider 11 to move in opposite directions. Only when the control slider 15 rises can the thrust of the control slider 15 and the connecting ear be greater than the elastic force of the two springs, so that the first horizontal slider 10 and the second horizontal slider 11 on both sides move towards each other. At the same time, when the control slider 15 falls, the horizontal springs 19 can drive the first horizontal slider 10 and the second horizontal slider 11 to move in opposite directions, so that the first paddle 12 and the second paddle 13 move in opposite directions.

[0043] In other embodiments, the first control wheel 16 and the second control wheel 17 can be mounted to the bottom of the first horizontal slider 10 and the second horizontal slider 11, and the control ears 18 are symmetrically arranged on both sides of the top of the control slider 15. Furthermore, the inner and outer mating positions of the first control wheel 16 and the second control wheel 17 with the symmetrical control ears 18 can be changed by connecting horizontal springs 19 at different positions, enabling the first horizontal slider 10 and the second horizontal slider 11 to move towards or away from each other by moving the control slider 15 up and down.

[0044] The bottom of the control slider 15 is provided with a second top wheel mounting block 20, on which a second top wheel 21 is mounted. The second top wheel 21 abuts against the return cam 8. At the same time, since the first horizontal slider 10 and the second horizontal slider 11 are provided with horizontal springs 19 on both sides, the first horizontal slider 10 and the second horizontal slider 11 will tend to move in opposite directions. The first horizontal slider 10 and the second horizontal slider 11 will transmit force through the first control wheel 16 and the second control wheel 17 and the opposing inclined surfaces on the connecting ear. The opposing movement of the first control wheel 16 and the second control wheel 17 will separate a downward force through the inclined surface of the connecting ear, so that the control slider 15 has a downward tendency. At this time, the second top wheel 21 can be kept in contact with the return cam 8.

[0045] The first top wheel mounting block 3 and the second top wheel mounting block 20 are far apart from each other. The first top wheel 4 and the second top wheel 21 are mounted on the side of the first top wheel mounting block 3 and the second top wheel mounting block 20 that are close to each other, so as to prevent the first top wheel mounting block 3 and the second top wheel mounting block 20 from affecting each other. The thickness of the first top wheel 4 and the second top wheel 21 is less than the thickness of the main cam 7 and the return cam 8. The first top wheel 4 and the second top wheel 21 are set close to the opposite side when they are on the main cam 7 and the return cam 8, so as to prevent the first top wheel 4 and the second top wheel 21 from contacting each other.

[0046] At this time, through the continuous contact between the main cam 7 and the return cam 8 on the conjugate cam 6 and the first top wheel 4 and the second top wheel 21 respectively, when the conjugate cam 6 rotates, the conjugate cam 6 can realize the rise and fall of the first driving plate 2 through the cooperation of the main cam 7 and the first top wheel 4, and realize the clamping and opening of the first paddle 12 and the second paddle 13 through the cooperation of the return cam 8 and the second top wheel 21.

[0047] The shapes of the main cam 7 and the return cam 8 of the conjugate cam 6 must meet the following requirements: In the initial state, the first driving plate 2 is located on the lower side and the first deflector 12 and the second deflector 13 are clamped together.

[0048] When the conjugate cam 6 starts to rotate, the first drive plate 2 is located on the lower side and the first paddle 12 and the second paddle 13 are opened;

[0049] The conjugate cam 6 continues to rotate, the first drive plate 2 is located on the upper side of the rising position, and the first paddle 12 and the second paddle 13 remain in the open state and rise synchronously;

[0050] As the conjugate cam 6 continues to rotate, the first drive plate 2 is located on the upper side and the first paddle 12 and the second paddle 13 are clamped together.

[0051] As the conjugate cam 6 continues to rotate, the first drive plate 2 is located on the upper side and the first paddle 12 and the second paddle 13 are clamped together.

[0052] The conjugate cam 6 continues to rotate, maintaining the first drive plate 2 on the upper side and the first paddle 12 and the second paddle 13 clamped together;

[0053] The conjugate cam 6 continues to rotate, returning to its initial state, with the first drive plate 2 located on the lower side and the first paddle 12 and the second paddle 13 clamped together.

[0054] Specifically, the shapes of the main cam 7 and the return cam 8 on the conjugate cam 6 should meet the following requirements: in the initial state of the conjugate cam 6, the first paddle 12 and the second paddle 13 are clamped together, and the initial position of the first driving plate 2 is located on the lower side. At this time, the motor drives the conjugate cam 6 to rotate, and the main cam 7 and the return cam 8 rotate synchronously, thereby causing the first top wheel 4 and the second top wheel 21, which are respectively engaged with the main cam 7 and the return cam 8, to start moving.

[0055] When the conjugate cam 6 rotates, the diameter of the main cam 7 remains unchanged. At this time, the height of the first drive plate 2 remains unchanged, the diameter of the return cam 8 increases, and the second top wheel 21, which cooperates with the return cam 8, drives the control slider 15 to rise. At this time, the rise of the control slider 15 causes the first transverse slider 10 and the second transverse slider 11 to move towards each other through the connecting ear. Since the initial state of the first paddle 12 and the second paddle 13 is a clamped state, when the first transverse slider 10 and the second transverse slider 11 move towards each other, the first transverse slider 10 and the second transverse slider 11 will cause the first paddle 12 and the second paddle 13 to open.

[0056] As the conjugate cam 6 continues to rotate, the diameter of the main cam 7 increases, and the diameter of the return cam 8 increases synchronously with the path of the main cam 7, causing the first paddle 12 and the second paddle 13 to rise synchronously with the first drive plate 2 in the open state.

[0057] Conjugate cam 6 continues to rotate. At this time, main cam 7 maintains the wheel diameter of the previous stage, while the wheel diameter of return cam 8 decreases. Return cam 8 causes control slider 15 to descend by lowering its wheel diameter. The descent of control slider 15 causes the first transverse slider 10 and the second transverse slider 11 to move in opposite directions under the action of transverse spring 19. At this time, the first paddle 12 and the second paddle 13 re-clamp.

[0058] The cam continues to rotate. At this time, the wheel diameters of the main cam 7 and the return cam 8 do not change. The first drive plate 2 is in an upward position, and the first paddle 12 and the second paddle 13 remain clamped to stabilize the machine structure.

[0059] As the cam continues to rotate, the wheel diameters of the main cam 7 and the return cam 8 decrease synchronously, causing the first drive plate 2 to return to its initial state on the lower side, and the first paddle 12 and the second paddle 13 to return to their initial clamping state.

[0060] The first top wheel 4 and the second top wheel 21 always maintain contact with the main cam 7 and the return cam 8 of the conjugate cam 6 to prevent the follower from bouncing off due to excessive speed. Driven by the cams, the two top wheels realize the graded movement of the follower.

[0061] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
