Abstract

This application pertains to the technical field of track locking mechanisms, specifically a track locking mechanism and conveying device. The track locking mechanism includes a base, a track support, and fastening components. The base includes a bottom plate and at least two side plates, which are positioned opposite each other at both ends of the bottom plate, forming a mounting groove. The track support is located within the mounting groove and has an inclined surface forming an angle A with the bottom of the mounting groove. The fastening components pass through the base and, together with the side plates of the mounting groove, provide lateral and longitudinal clamping of the inclined surface to secure the track support.

Furthermore, it eliminates the need for complex devices to secure the track support, reducing production costs.

Description

Technical Field

[0001] This application relates to the field of track locking technology, and more specifically, to a track locking mechanism and a conveying device. Background Technology

[0002] Existing wire bonding machines typically use a conveying system consisting of two tracks. The workpiece is held between these tracks and delivered along them. During operation, these tracks vibrate in both vertical and horizontal directions. This vibration can loosen the connection between the track support and the base, causing changes in the distance between the tracks and resulting in workpiece displacement or detachment. Current technology uses cross-ball bearing guides as a track locking mechanism, which is complex and costly. Summary of the Invention

[0003] The technical problem to be solved by the embodiments of this application is that the existing track locking mechanism is costly and has a complex structure.

[0004] To address the aforementioned technical problems, this application provides a track locking mechanism, employing the following technical solution:

[0005] The track locking mechanism includes:

[0006] The base includes a bottom plate and at least two side plates, the two side plates being disposed opposite each other at both ends of the bottom plate and forming a mounting groove with the bottom plate;

[0007] The track support is located in the mounting groove and has an inclined surface, which forms an angle A with the bottom of the mounting groove;

[0008] A fastening assembly, which passes through the base, is able to work with the side plate of the mounting groove to clamp the inclined surface laterally and longitudinally, thereby fixing the track support.

[0009] Furthermore, the included angle A is between 10° and 80°.

[0010] Furthermore, the side plate includes a first side plate and a second side plate, with the inclined surface facing the first side plate;

[0013] The driving member can push the abutment to move along the inclined surface so that the abutment abuts against the mounting plate and the inclined surface.

[0014] Furthermore, the supporting member is a cylinder, which is capable of rolling along the inclined plane.

[0015] Furthermore, the mounting plate also includes a first [missing information - likely a number] disposed opposite to the moving groove along its length direction.

[0016] The first fold and the second fold, wherein the abutment is located between the first fold and the second fold, and the first fold and the second fold are used to restrict the axial movement of the abutment.

[0017] Furthermore, the side plate includes a first side plate and a second side plate, wherein the first side plate is inclined to the bottom plate and parallel to the inclined surface;

[0018] The fastening assembly is inserted through the first side plate and can move in a direction perpendicular to the inclined plane and abut against the inclined plane.

[0019] Furthermore, a gasket is provided between the inner wall of the first side plate and the inclined surface, and the fastening assembly abuts against the gasket.

[0020] Furthermore, the side plate includes a first side plate and a second side plate, wherein the first side plate is provided with a supporting surface, the supporting surface being parallel to the inclined surface;

[0021] The fastening component is inserted through the second side plate and can push the track support to move toward the abutment surface so that the abutment surface abuts against the inclined surface.

[0023] Furthermore, the conveying device includes a first track, a second track, and at least two track locking mechanisms, wherein the first track and the second track are arranged opposite to each other to clamp the workpiece;

[0024] The track locking mechanism includes two track support seats and two bases, with the two track support seats respectively connected to the two bases for clamping the first track and the second track;

[0025] The track support seats located in different track locking mechanisms can move relative to each other to adjust the distance between the first track and the second track.

[0026] Compared with the prior art, the embodiments of this application have the following main advantages:

[0027] The track support base of this application is located in the mounting groove. When the fastening assembly abuts against the inclined surface, the force applied to the inclined surface by the fastening assembly is converted into longitudinal and lateral forces. The track support base is longitudinally clamped by the fastening assembly and the base plate, and also laterally clamped by the fastening assembly and the side plate. Therefore, it can resist lateral and longitudinal vibrations, maintain the stability of the track locking mechanism, and eliminate the need for complex devices such as cross ball bearing guides to fix the track support base, thus reducing production costs.

Detailed Implementation

[0045] 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. Furthermore, it should be understood that the specific embodiments described herein are only for illustration and explanation of this application and are not intended to limit this application.

[0046] In this application, unless otherwise stated, directional terms such as "upper" and "lower" generally refer to the upper and lower positions of the device in its actual use or operating state, specifically the orientation shown in the accompanying drawings; while "inner" and "outer" refer to the outline of the device. Furthermore, in the description of this application, the term "comprising" means "including but not limited to". The terms first, second, third, etc., are used merely as illustrative purposes and do not impose numerical requirements or establish a numerical order.

[0047] In this application, "and / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. A and B can be singular or plural.

[0048] In this application, "at least one" means one or more, and "more than one" means two or more. "At least one," "at least one of the following," or similar expressions refer to any combination of these items, including any combination of single or multiple items. For example, "at least one of a, b, or c," or "at least one of a, b, and c," can both mean: a, b, c, ab (i.e., a and b), ac, bc, or abc, where a, b, and c can be single or multiple.

[0049] Various embodiments of this application may exist in the form of a range; it should be understood that the description in the form of a range is merely for convenience and brevity and should not be construed as a hard limitation on the scope of this application; therefore, it should be considered that the range description has specifically disclosed all possible sub-ranges and single numerical values ​​within that range. For example, it should be considered that the range description from 1 to 6 has specifically disclosed sub-ranges such as from 1 to 3, from 1 to 4, from 1 to 5, from 2 to 4, from 2 to 6, from 3 to 6, etc., and single numbers within the range, such as 1, 2, 3, 4, 5, and 6, regardless of the range. Furthermore, whenever a numerical range is referred to herein, it means including any referenced number (fraction or integer) within the referred range.

[0050] Please refer to Figures 1 to 5 In the figure, the Z direction represents the longitudinal and vertical directions, the X direction represents the transverse and left-right directions, and the Y direction represents the axial direction. The track locking mechanism 20 includes: a base 200, including a bottom plate 230 and at least two side plates, the two side plates being disposed opposite each other at both ends of the bottom plate 230 and forming a mounting groove with the bottom plate 230; a track support 100, located in the mounting groove, having an inclined surface 110, the inclined surface 110 forming an angle A with the bottom of the mounting groove; and a fastening assembly 300, which passes through the base 200 and can work with the side plates of the mounting groove to achieve transverse and longitudinal clamping of the inclined surface 110, thereby fixing the track support 100.

[0051] The track support 100 of this application is located in the mounting groove. During operation, it can be held against the inclined surface 110 by controlling the fastening assembly 300. Because the inclined surface 110 is inclined to the base plate 230, the force applied to the inclined surface 110 by the fastening assembly 300 is converted into longitudinal and lateral forces. At this time, the track support 100 is longitudinally clamped by the fastening assembly 300 and the base plate 230, and also laterally clamped by the fastening assembly 300 and the side plate. Therefore, it can resist lateral and longitudinal vibrations and maintain the stability of the track locking mechanism 20. This solution does not require the addition of complex devices such as cross ball bearing guides to fix the track support 100, thus reducing production costs.

[0052] It is understood that the side plate and the base plate 230 can be integrally formed or fixedly connected. The fastening assembly 300 may include a motor-driven mechanism to automatically clamp or release the track support 100. The fastening assembly 300 may include a screw, the movement of which clamps or releases the track support 100.

[0053] Further, please refer to Figure 2 The included angle A is between 10° and 80°. The size of included angle A affects the decomposition of the force applied to the inclined plane 110, where part of the force is perpendicular to the inclined plane 110 (longitudinal force) and another part is parallel to the inclined plane 110 (lateral force). A smaller included angle A results in more force being decomposed into lateral forces, while a larger included angle A results in more force being decomposed into longitudinal forces. When included angle A is between 10° and 80°, a balance between lateral and longitudinal forces can be maintained. The included angle A can be 10°–20°, 20°–30°, 30°–40°, 40°–50°, 50°–60°, 60°–70°, or 70°–80°. Preferably, when included angle A is 45°, the force applied to the inclined plane 110 by the fastening assembly 300 can be evenly divided into lateral and longitudinal forces.

[0054] Specific Embodiment 1 of the Track Locking Mechanism 20 provided in this application

[0055] Please refer to Figure 3 The side plate includes a first side plate 210 and a second side plate 220, with the inclined surface 110 facing the first side plate 210; the base 200 also includes a mounting plate 240, which is connected to the first side plate 210, parallel to the bottom plate 230, and forms a moving groove 250 with the first side plate 210, the inclined surface 110, and the bottom plate 230; the fastening assembly 300 includes a supporting member 320 and a driving member 310, with the driving member 310 passing through the first side plate 210 and the supporting member 320 located in the moving groove 250; wherein, the driving member 310 can push the supporting member 320 to move along the inclined surface 110 so that the supporting member 320 abuts against the mounting plate 240 and the inclined surface 110.

[0056] When it is necessary to clamp the track support 100, the abutment 320 can be controlled to move laterally toward the inclined plane 110. Driven by the drive member 310, the abutment 320 moves along the inclined plane 110 toward the mounting plate 240, ultimately abutting against the lower surface of the mounting plate 240 and the inclined plane 110. At this time, the track support 100 is clamped by the second inclined plane 110, the base plate 230, and the abutment 320, and is subjected to both lateral and longitudinal forces, thus exhibiting good stability. When it is necessary to adjust the position of the track support 100, the drive member 310 can be controlled to move away from the track support 100. At this time, the abutment 320 returns to its original position, releasing the clamp on the track support 100, allowing for position adjustment.

[0057] It is understood that the materials of the mounting plate 240 include, but are not limited to, steel, stainless steel, ceramics, high carbon steel, titanium alloy, chromium alloy, tantalum, zirconium alloy, and any combination thereof. The connection methods between the mounting plate 240 and the first side plate 210 include, but are not limited to, threaded connection, locking connection, welding connection, mortise and tenon connection, bending connection, pressure connection, adhesive connection, riveting connection, clamping connection, snap-fit ​​connection, and integral molding, and any combination thereof. An opening B is formed between the mounting plate 240 and the inclined surface 110. The width of opening B should be less than the width of the abutment 320, thereby preventing the abutment 320 from sliding out of the moving groove 250. The abutment 320 can be a slider, cylinder, or sphere to adapt to different shaped moving grooves 250. The mounting plate 240 can also be integrally molded with the base 200.

[0058] Further, please refer to Figure 3 The abutment 320 is a cylinder, which can roll along the inclined plane 110. As the number of times the abutment 320 moves along the inclined plane 110 increases, the inclined plane 110 or the abutment 320 is easily worn, causing the opening B to increase and the width of the abutment 320 to decrease, which in turn causes the abutment 320 to slip out of the mounting groove, and the track support 100 to fail to stay in place. Therefore, when the abutment 320 is a cylinder, the cylinder can roll along the inclined plane 110, and the rolling friction is less than the sliding friction, thus reducing the wear of the abutment 320 and preventing the opening B from increasing.

[0059] Further, please refer to Figure 2 and Figure 3The axial direction of the abutment 320 is the Y direction as shown in the figure. The mounting plate 240 also includes a first flange 241 and a second flange 242 disposed opposite to each other along the length direction of the moving groove 250. The abutment 320 is located between the first flange 241 and the second flange 242, and the first flange 241 and the second flange 242 are used to restrict the axial movement of the abutment 320. When the track 600 delivers the workpiece 500, axial vibration may also occur, which may cause the abutment 320 to shift axially. At the same time, when the drive member 310 is not abutting against the abutment 320, the abutment 320 may also slip out of the mounting groove due to accidental contact or other reasons. The first flange 241 and the second flange 242 provided in this application can restrict the axial movement of the abutment 320, thereby preventing the abutment 320 from slipping out.

[0060] Specific Embodiment Two of the Track Locking Mechanism 20 Provided in this Application

[0061] Please refer to Figure 4 The side plates include a first side plate 210 and a second side plate 220. The first side plate 210 is inclined to the base plate 230 and parallel to the inclined plane 110. A fastening assembly 300 passes through the first side plate 210 and can move in a direction perpendicular to the inclined plane 110 and abut against the inclined plane 110. At this time, the fastening assembly 300 can be driven to move in a direction perpendicular to the inclined plane 110 to abut against or move away from the inclined plane 110. When the fastening assembly 300 abuts against the inclined plane 110, the fastening assembly 300 and the second side plate 220 clamp the track support 100 laterally, and the fastening assembly 300 and the base plate 230 clamp the support longitudinally. Therefore, the track locking mechanism 20 of this embodiment has high stability.

[0062] Further, please refer to Figure 4 A gasket 400 is provided between the inner wall of the first side plate 210 and the inclined surface 110, and the fastening component 300 abuts against the gasket 400. Because the contact area between the fastening component 300 and the inclined surface 110 is usually small, the fastening component 300 is prone to imprinting grooves on the inclined surface 110, thereby reducing the stability of the track locking mechanism 20. In this embodiment, the track locking mechanism 20 adds a gasket 400 between the inner wall of the first side plate 210 and the inclined surface 110. In this case, the gasket 400 directly contacts the fastening component 300 instead of the inclined surface 110. Even if the gasket 400 imprints grooves, it can be quickly replaced, resulting in lower costs. Therefore, this application reduces the maintenance cost of the track locking mechanism 20.

[0063] It is understood that the materials of gasket 400 include, but are not limited to, any one or a combination of alloys, metals, ceramics, rigid plastics, composite materials, graphite, carbon fiber, etc.

[0064] Specific Embodiment Three of the Track Locking Mechanism 20 Provided in this Application

[0065] Please refer to Figure 5 The side plate includes a first side plate 210 and a second side plate 220. The first side plate 210 is provided with a supporting surface, which is parallel to the inclined surface 110. The fastening component 300 passes through the second side plate 220 and can push the track support 100 towards the supporting surface so that the supporting surface abuts against the inclined surface 110. At this time, the locking structure can push the track support 100 towards the supporting surface laterally, so that the inclined surface 110 fits and abuts against the supporting surface. At this time, the track support 100 is jointly clamped laterally and longitudinally by the fastening component 300, the supporting surface, and the base plate 230, and the track locking mechanism 20 has high stability.

[0066] It is understood that the above three embodiments of the track locking mechanism 20 can be used in combination. That is, the bottom of the track support 100 has two opposing inclined surfaces 110, and the first side plate 210 and the second side plate 220 are both provided with fastening components 300. At this time, the two inclined surfaces 110 of the track support 100 are clamped by the fastening components 300. The two fastening components 300 and the base plate 230 together complete the lateral and longitudinal fixation of the track support 100.

[0067] Please refer to Figure 1 This application embodiment also provides a conveying device 10 for conveying workpiece 500. The conveying device 10 includes the track locking mechanism 20 as described above. Because the conveying device 10 includes the track locking mechanism 20 as described above, the conveying device 10 has a simple structure and low cost.

[0068] Further, please refer to Figure 1 The conveying device 10 includes a first track 600, a second track 600, and at least two track locking mechanisms 20. The first track 600 and the second track 600 are arranged opposite to each other to clamp the workpiece 500. The track locking mechanism 20 includes two track support seats 100 and two bases 200. The two track support seats 100 are respectively connected to the two bases 200 for clamping the first track 600 and the second track 600. The track support seats 100 located in different track locking mechanisms 20 can move relative to each other to adjust the distance between the first track 600 and the second track 600, so that the conveying device 10 can adapt to workpieces 500 of different sizes.

[0069] The present application will be specifically described below through specific embodiments. The following embodiments are only some embodiments of the present application and are not intended to limit the present application.

[0070] In comparison, the track support and base are fixed using cross ball bearing guides.

[0071] Example A: This example provides a conveying device. The conveying device adopts the track locking mechanism provided in Example 1 of this application. The supporting member is a cylinder, and the driving member is a screw.

[0072] Example B: This example provides a conveying device. The conveying device adopts the track locking mechanism provided in Example 2 of this application. The included angle A is 60°, the fastening component is a screw, and a washer is provided.

[0073] Example C: This example provides a conveying device. The conveying device adopts the track locking mechanism provided in Example 3 of this application. The included angle A is 60° and the fastening component is a screw.

[0074] Example D is basically the same as Example A, except that the included angle is 45°.

[0075] The above comparative examples and embodiments were subjected to a load-bearing test. The load-bearing test was conducted by tightening the screw (rotating the screw until it is locked) along... Figure 1 The track support is pushed in the Y direction until the track support and the base move relative to each other. The force applied to the track support at this time is measured as the bearing force. The bearing force of the comparative embodiment is taken as 100%, and the bearing force of the other embodiments is taken as an indicator relative to the bearing force of the comparative embodiment.

[0076] The life test conditions are as follows: Workpieces are transported using this conveyor device, and the offset of multiple workpieces' positions (along the conveyor) is measured after they have completed their full movement through the device. Figure 1 The degree of deviation from the preset path in the Y direction is calculated, and the average of this deviation is recorded as the base deviation. When the base deviation reaches 0.1 mm, the conveying time is used as the lifespan indicator, with the unit being hours (h). The lifespan of the comparative example is taken as 100%, and the lifespan of the other embodiments is used as an indicator relative to the lifespan of the comparative example. The results are shown in Table 1 below.

[0077] Table 1:

[0078]

[0079] Based on the test results of the comparative examples and embodiments A to C, it can be seen that the stability and service life of the three embodiments of this application are similar to or better than those of the comparative examples using cross ball guides.

[0080] According to the test results of Examples A to C, Example B in this application has the highest service life and stability because the force on the inclined surface is more uniform and the contact area between the inclined surface and the first side plate is larger.

[0081] According to the test results of Embodiments A and D, the included angle A of the inclined plane in this application embodiment will affect the stability and service life of the track locking mechanism in this application, and when the included angle A is 45°, its stability and service life are relatively high.

[0082] In some embodiments, please refer to Figures 6 to 14 The conveying device 10 includes a base 10, a track, a track support 100, and an adjustment assembly (not marked in the figure);

[0083] The track support 100 supports the track, and the track support 100 is disposed on the base 200;

[0084] The adjustment component is detachably connected to the track support 100 and is used to adjust the position of the track support 100.

[0085] In this application, the position of the track support can be adjusted by adjusting the component, thereby changing the current position of the track. This allows for adjusting the track's clamping or supporting function on the workpiece. Because of the adjustment component, this application offers higher precision and efficiency compared to manual adjustment. Furthermore, the adjustment component is detachably connected to the track support, facilitating its maintenance and replacement.

[0086] Furthermore, when adjusting the spacing between the track supports, manually pushing the track supports results in low adjustment efficiency and low accuracy. For example, when the track supports are connected to the base using any of the methods described in embodiments one, two, and three above, the friction between the track supports and the base is sliding friction (dry friction), making it difficult to manually push the track supports and guarantee accuracy. In this case, an adjustment tool needs to be designed to adjust the distance between the track supports.

[0087] In some embodiments, please refer to Figures 6 to 10 , Figure 1 In this embodiment, the X direction is the left-right direction, the Y direction is the front-back direction, and the Z direction is the up-down direction. Each track support 100 carries a track, and the track support 100s are arranged in pairs on both sides of the base 200.

[0088] The base 200 supports the track support 100. The surface of the base 200 facing the track support 100 is provided with at least one adjustment groove 260, which is located within the projection area of ​​the track support 100 on the base 200.

[0089] The adjustment assembly includes a first adjustment member, and the first adjustment member 700 includes a first connecting portion 710 and an adjustment protrusion 720 connected in sequence.

[0090] The first connecting part 710 passes through the track support 100, and the adjusting protrusion 720 protrudes from the first connecting part 710 toward the base 200, is located in the adjusting groove 260, and has a gap between it and the central axis of the first connecting part 710.

[0091] The adjustment principle of the conveying device 10 in this application is as follows: First, please refer to... Figure 6 The first adjusting member 700 is passed vertically through the track support 100, so that the adjusting protrusion 720 is inserted into the adjusting groove 260; at this time, the first connecting part 710 is rotated clockwise (clockwise from top to bottom) along its own central axis. Please refer to... Figure 9a and Figure 9b , Figure 9a When the first adjusting member 700 rotates clockwise, because there is a gap between the adjusting protrusion 720 and the central axis of the first connecting part 710, the first adjusting member 700 rotates eccentrically while the base 200 remains stationary. Then, because the first adjusting member is inserted into the track support 100, the first adjusting member 700 will drive the track support 100 to move during the eccentric rotation, thereby achieving efficient adjustment of the gap between adjacent track support 100s without manual pushing.

[0092] It should be understood that when the length of the adjusting groove 260 is greater than the diameter of the adjusting protrusion 720, the first adjusting member 700 will no longer rotate eccentrically. Instead, the rotational motion will be converted into sliding of the adjusting protrusion 720 in the adjusting groove 260, forming a type of eccentric wheel structure. This converts rotation into linear movement, thereby linearly adjusting the distance between adjacent track support seats 100 and preventing the position of the track support seats 100 from shifting except for relative movement (movement in the front-back direction). Simultaneously, this application converts large-amplitude rotation into small-amplitude movement, achieving precise control of the distance between the track support seats 100.

[0093] The track support 100 may be provided with a through hole (not marked in the figure) for the first adjusting member 700 to pass through. If the track support 100 is as follows... Figure 1 As shown, there are multiple overlapping structures in the vertical direction. The first adjusting member 700 can pass through the multiple overlapping structures. At this time, multiple parts of the first adjusting member 700 are inserted into the track support seat 100, which is equivalent to multiple points of force. Its stability is high and it is not easy to bend during the adjustment process.

[0094] For further details, please refer to... Figure 6 and Figure 8The first adjusting member 700 also includes a first gripping portion 730, which is connected to the end of the first connecting portion 710 away from the adjusting protrusion 720 and protrudes in a direction away from the side wall of the first connecting portion 710. Because the first adjusting member 700 needs to rotate, its shape is usually cylindrical to prevent the track support 100 from rotating with it. However, a cylindrical shape is difficult to grip when rotating, resulting in low efficiency for the operator in adjusting the track support 100.

[0095] This application provides a first gripping part 730 at one end of the first adjusting member 700's principle adjusting protrusion 720. Because the first gripping part 730 protrudes away from the sidewall of the first connecting part 710, the first adjusting member 700 will form a T-shaped structure. At this time, the operator can grip the first gripping part 730 and rotate the first adjusting member 700. It should be understood that the shape of the first connecting part 710 can also be square, triangular prism, etc., as long as the through hole on the track support 100 for the first connecting part 710 to pass through is circular. However, in this case, the first connecting part 710 will not be able to completely fit against the sidewall of the through hole. Therefore, when the first adjusting member 700 rotates, its contact surface with the track support 100 is small, and it is prone to breakage.

[0096] For further details, please refer to... Figure 8 The first connecting part 710 includes a main body 711 and a head 713. One end of the main body 711 is connected to the first gripping part 730, and the other end is provided with a snap-fit ​​groove 712. One end of the head 713 is provided with an adjusting protrusion 720, and the other end is provided with a snap-fit ​​protrusion 714. The snap-fit ​​protrusion 714 is inserted into the snap-fit ​​groove 712, and its shape and size are adapted to the snap-fit ​​groove 712. The size of the adjusting protrusion 720 and the distance between the adjusting protrusion 720 and the central axis of the first connecting part 710 will affect the adjustment efficiency of the first adjusting member 700 on the distance of the track support seat 100. For example, the larger the distance between the adjusting protrusion 720 and the central axis of the first connecting part 710, the longer the distance that the first adjusting member 700 can move the track support seat 100 for each rotation. The adjustment protrusion 720 needs to be replaced according to actual needs. Because the diameter of the adjustment protrusion 720 is smaller than that of the first connecting part 710 and it is subjected to greater shear force, it is more prone to breakage than the first connecting part 710.

[0097] In summary, a first adjusting member 700 that facilitates the replacement of the adjusting protrusion 720 needs to be designed. The first adjusting member 700 of this application has a first connecting portion 710 divided into two parts: its main body 711 is connected to the first gripping portion 730, this part is subject to less force and is less prone to breakage; the head 713 and the main body 711 are connected by a snap-fit ​​groove 712 and a snap-fit ​​protrusion 714. Figure 8As can be seen, after the snap-fit ​​protrusion 714 is inserted into the snap-fit ​​slot 712, when the main body 711 rotates, it will drive the head 713 to rotate, thereby achieving the adjustment of the track support 100. Therefore, this application can achieve the function of quickly adjusting the protrusion 720.

[0098] For further details, please refer to... Figure 6 As shown in Figure 9, the maximum distance from the side wall of the adjusting protrusion 720 to the center of the first connecting part 710 is the first distance, and the length of the adjusting groove 260 is greater than the first distance. At this time, the adjusting protrusion 720 can move a longer distance in the adjusting groove 260, so that the first connecting part 710 can rotate one revolution, and the first adjusting member 700 is prevented from being jammed by the side wall of the adjusting groove 260 too early.

[0099] The adjusting protrusion 720 is cylindrical, and its diameter is equal to the width of the adjusting groove 260. If the diameter of the adjusting protrusion 720 is smaller than the width of the adjusting groove 260, then in the initial stage of rotation of the first adjusting member 700, the adjusting protrusion 720 has not yet contacted the side wall of the adjusting groove 260. At this time, although the first adjusting member 700 rotates, the track support 100 cannot move, resulting in an error between the adjustment result and the expected effect. Simultaneously, if the diameter of the adjusting protrusion 720 is smaller than the width of the adjusting groove 260, the first adjusting member 700 cannot perform its positioning function for the track support 100.

[0100] Please refer to Figure 6 The adjustment grooves 260 are multiple, and are arranged sequentially along the spacing direction of adjacent track support seats 100. Adjusting the spacing between track support seats 100 via the first adjustment member 700 is typically precise, and the adjustable distance is limited. If the required adjustment distance is too long, multiple adjustment grooves 260 can be designed to extend the length of the track support seat 100 that the first adjustment member 700 can adjust.

[0101] For further details, please refer to... Figures 6 to 13 The track support 100 includes a first track support 130 and a second track support 140 disposed opposite to each other, and both the first track support 130 and the second track support 140 are provided with tracks;

[0102] The adjustment assembly also includes a second adjustment member 800, which includes a second connecting part 810, a second connecting part 820, and a second connecting part 830.

[0103] The second connecting part 810 is provided with a thread at one end facing the second track support 140, and is threadedly connected to the second track support 140;

[0104] The second connecting part 820 is sleeved on the second connecting part 810 through the second connecting part 830, covering part of the second connecting part 810. The side wall of the second connecting part 820 is provided with a first annular snap-fit ​​groove 821, which passes through the first track support 130. At least part of the first track support 130 is snapped into the first annular snap-fit ​​groove 821.

[0105] Please refer to Figure 12 and Figure 13 The working principle of the second adjusting component 800 is as follows:

[0106] First, the second adjusting member 800 is passed through the first track support 130 along the direction from the first track support 130 to the second track support 140, so that a portion of the first support 130 is located in and locked by the first annular locking groove 821. Then, the second adjusting member 800 is rotated so that the threaded end of the second adjusting member 800 is threadedly connected to the second track support 140. Next, the second connecting part 820 and the second connecting part 810 are fixedly connected by the second connecting part 830. At this time, if the second connecting part 810 is pulled, the first track support 130 and the second track support 140 will move synchronously. If the fixing effect of the second connecting part 830 is released, the second track support 140 will move when the second connecting part 810 moves, but the first track support 130 will not move, thus achieving adjustment of the distance between the two track supports 100.

[0107] For further details, please refer to... Figure 12 and Figure 13 The second connecting part 830 is a screw 30, the second connecting part 810 is provided with a second annular snap-fit ​​groove 811, the second connecting part 820 is provided with a connecting through hole (not marked in the figure), the second connecting part 830 passes through the connecting through hole, and is at least partially located in the second annular snap-fit ​​groove 811; it can be understood that, in order to adapt to the first track support 130 and the second track support 140 with different spacing, there can be multiple second annular snap-fit ​​grooves and connecting through holes.

[0108] The second adjusting member 800 also includes a second gripping portion 840, which is connected to the second connecting portion 810 away from the thread and protrudes in a direction away from the side wall of the second connecting portion 810. At this time, the second connecting portion 810 can be moved by gripping the second gripping portion 840.

[0109] For further details, please refer to... Figure 6 , Figure 13 and Figure 14 The first track support 130 is provided with a first sleeve mounting hole 110 and a second sleeve mounting hole 120. The first sleeve mounting hole 110 and the second sleeve mounting hole 120 are connected, and the second connecting part 820 is located in the second sleeve mounting hole 120.

[0110] The diameter of the first sleeve mounting hole 110 is greater than or equal to the outer diameter of the first annular snap groove 821, and the diameter of the second sleeve mounting hole 120 is equal to the inner diameter of the first annular snap groove 821.

[0111] Because the second connecting part 820 has a first annular snap-fit ​​groove 821, if the size of the through hole on the track support 100 is equal to the outer diameter of the first annular snap-fit ​​groove 821, although the second connecting part 820 can pass through the first track support 130, the contact area between the inner wall of the first annular snap-fit ​​groove 821 and the first track support 130 will be reduced, and the second connecting part 820 may wobble in the through hole. Therefore, this application designs a first sleeve mounting hole 110 for the second connecting part 820 to pass through, and the inner diameter of the second sleeve mounting hole 120 is equal to that of the first annular snap-fit ​​groove 821, which can play a role in fixing the second connecting part 820, thereby preventing the second adjusting member 800 from wobble.

[0112] Accordingly, this application also provides a wire bonding machine, which includes the conveying device 10 as described above. Because the wire bonding machine includes the conveying device 10 as described above, the wire bonding machine of this application can adjust the spacing between adjacent track support seats 100 in the conveying device 10, and convert large-scale rotation into small-scale movement, thereby achieving precise control of the spacing between the track support seats 100.

[0113] The present application will be specifically described below through specific embodiments. The following embodiments are only some embodiments of the present application and are not intended to limit the present application.

Each track support 100 carries a track, and the track support 100s are arranged in pairs on both sides of the base 200. The base 200 carries the track support 100, and at least one adjustment groove 260 is provided on the surface of the base 200 facing the track support 100. The adjustment groove 260 is located in the projection area of ​​the track support 100 on the base 200. The first adjustment member 700 includes a first connecting part 710 and an adjustment protrusion 720 connected in sequence. The first connecting part 710 passes through the track support 100, and the adjustment protrusion 720 protrudes from the first connecting part 710 in the direction facing the base 200, is located in the adjustment groove 260, and has a gap between it and the central axis of the first connecting part 710.

[0116] The fastening assembly 300 and the side plate 201 form a horizontal preload of 50N to vertically clamp the bottom of the base. The screw 30 and the threaded groove 270 cooperate to form a vertical preload of 50N to clamp the bottom of the track support.

[0128] Comparative Example 1

[0130] Comparative Example 2

The screw 30 and the threaded groove 270 cooperate to form a vertical preload of 500N to clamp the bottom of the track support.

[0132] Measurement methods

[0133] After the track support seat moves 10mm, use a tension gauge to pull the track support seat in Comparative Example 1 and record the tension displayed on the tension gauge. Use this tension as the base tension, set to 100%. Use this conveyor device to transport workpieces. After the track support seat moves 10mm, measure the positional offset of 50 workpieces after they have completed their movement through the conveyor device. Figure 1 (In the 5th direction), calculate the average of the offsets and record it as the base offset, with its magnitude recorded as 100%;

[0134] Two force gauges are connected to the two ends of the first connecting part in Embodiments 1 and 3, making the force gauges and the first connecting part at a right angle. Then, the two force gauges are pulled clockwise, causing them to drive the first adjusting member to... Figure 1Rotate clockwise from top to bottom, and record the sum of the values ​​on the tension gauges of Examples 1 and 3 when the track support begins to move. Compare this sum with the tension in Comparative Example 1. After the track support moves 10mm, measure the offset of the position of 50 workpieces after they have completed their movement through the conveyor device. Figure 5 (In the Y direction), calculate the average of the offsets and record it as the base offset. Compare its magnitude with the offset in Comparative Example 1.

[0135] Two force gauges are connected to the two ends of the second connecting parts of Embodiments 2 and 4, making the force gauges and the first connecting parts at right angles. The force gauges are then pulled, and the combined pulling force is recorded and compared with Comparative Example 1. After the track support seat moves 10mm, the offset of the position of 50 workpieces after their complete movement through the conveyor device is measured (along...). Figure 1 The degree of deviation from the preset path in the Y direction is calculated, and the average of this offset is recorded as the base offset.

[0136] The offset of Comparative Example 1 is taken as 100%. The offsets of the other embodiments and comparative examples are compared with the offset of Comparative Example 1 (for example, the average offset of Comparative Example 1 is 1 mm, and the average offset of Example 1 is 0.83 mm, then the offset of Example 1 is recorded as 0.83 / 1 = 83%).

[0137] Based on the above experimental data, the following table was obtained:

[0138] Table 2:

[0139]

[0140]

[0141] As shown in Table 2:

[0142] According to Comparative Example 2, when both the vertical preload and the horizontal preload are greater than 500N, when the track support is adjusted by the existing manual pushing method, even if the tension is increased to ten times the original, the track support still cannot be moved. The magnitude of the tension and the amount of offset are meaningless. That is, the adjustment method of manually pushing the track support is less efficient than adjusting with tools such as the first and second adjusting parts.

[0143] As can be seen from Examples 1 and 2 and Comparative Example 1, the adjustment method using the first and second adjusting components can reduce the force required for the moving track support, resulting in high force transmission efficiency. Simultaneously, it can also reduce the offset rate of the workpiece transported after the track support is adjusted, thus improving the accuracy of the conveying device and increasing the workpiece yield.

[0144] As can be seen from Examples 1 to 6 and Comparative Examples 1 and 2, when the preload increases, all three adjustment methods require a corresponding increase in force, thereby causing the track support to move. The first adjustment component requires a smaller increase in tension. Since vibration or operational errors during adjustment can easily cause offset, and the first adjustment component exhibits the smallest increase in offset, it demonstrates that it can achieve high-precision position adjustment even under high preload.

[0145] In summary, this application can improve the adjustment accuracy and efficiency of the track spacing of the conveying device.
