DETAILED DESCRIPTION

[0044] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of this application. In addition, it should be understood that the specific embodiments described herein are only used to illustrate and explain the present application and are not used to limit the present application.

[0045] In this application, unless otherwise indicated, directional terms such as "upper" and "lower" generally refer to the upper and lower positions of a device in actual use or operation, specifically in the drawing directions of the accompanying drawings; whereas "inner" and "outer" refer to the outline of the device. Furthermore, in the description of this application, the term "including" means "including but not limited to." Terms such as first, second, and third are used merely as designations and do not impose numerical requirements or establish a sequential order.

[0046] In this application, "and / or" describes the association relationship between associated objects, indicating that three relationships can exist. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. A and B can be singular or plural.

[0047] In this application, "at least one" means one or more, and "plurality" 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 items or plural items. For example, "at least one of a, b, or c", or "at least one of a, b, and c" can all mean: a, b, c, ab (i.e., a and b), ac, bc, or abc, where a, b, and c can be single or multiple.

[0048] Various embodiments of the present application may be presented in the form of a range; it should be understood that the description in the form of a range is only for convenience and brevity and should not be construed as a hard limitation on the scope of the present application; therefore, the range description should be considered to have specifically disclosed all possible sub-ranges and single numbers within the range. For example, the description of a range from 1 to 6 should be considered to have 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., as well as single numbers within the range, such as 1, 2, 3, 4, 5 and 6, which applies regardless of the range. In addition, whenever a numerical range is indicated herein, it is meant to include any cited number (fractional or integer) within the indicated range.

[0049] Please refer to Figures 1 to 5 In the figure, the Z direction is the longitudinal and up-down direction, the X direction is the lateral and left-right direction, and the Y direction is 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 are arranged at opposite ends of the bottom plate 230 and enclosed with the bottom plate 230 to form a mounting groove; a track support seat 100, located in the mounting groove, provided with an inclined surface 110, and the inclined surface 110 forms an angle A with the bottom of the mounting groove; a fastening assembly 300, which is passed through the base 200 and can work together with the side plates of the mounting groove to achieve horizontal and vertical clamping of the inclined surface 110 to fix the track support seat 100.

[0050] The track support seat 100 of the present application is located in the mounting groove, and when in operation, the fastening assembly 300 can be controlled to support the inclined surface 110. Because the inclined surface 110 is inclined to the base plate 230, the force applied by the fastening assembly 300 on the inclined surface 110 will be converted into longitudinal force and lateral force. At this time, the track support seat 100 is longitudinally clamped by the fastening assembly 300 and the base plate 230, and is also transversely clamped by the fastening assembly 300 and the side plate, so it can resist transverse 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 guides to fix the track support seat 100, thereby reducing production costs.

[0051] It is understood that the side panels and the bottom panel 230 may 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 that is moved to clamp or release the track support 100.

[0052] For further information, please refer to Figure 2 . The size of the angle A is 10° to 80°. The size of the angle A will affect the decomposition of the force applied to the inclined surface 110, wherein a part of the force is perpendicular to the inclined surface 110 (longitudinal force), and the other part of the force is parallel to the inclined surface 110 (lateral force). A smaller angle A will cause more force to be decomposed into lateral force, while a larger angle A will cause more force to be decomposed into longitudinal force. When the angle A is 10° to 80°, the balance between the lateral force and the longitudinal force can be maintained. The angle A can be 10° to 20°, 20° to 30°, 30° to 40°, 40° to 50°, 50° to 60°, 60° to 70°, or 70° to 80°. Preferably, when the angle A is 45°, the force applied to the inclined surface 110 by the fastening assembly 300 can be evenly divided into lateral force and longitudinal force.

[0053] Specific embodiment 1 of the track locking mechanism 20 provided in the embodiment of the present application

[0054] Please refer to Figure 3 The side panel includes a first side panel 210 and a second side panel 220, and the inclined surface 110 faces the first side panel 210; the base 200 also includes a mounting plate 240, which is connected to the first side panel 210, parallel to the bottom panel 230, and forms a movable groove 250 with the first side panel 210, the inclined surface 110, and the bottom panel 230; the fastening assembly 300 includes a supporting member 320 and a driving member 310, the driving member 310 is passed through the first side panel 210, and the supporting member 320 is located in the movable 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 is abutted against the mounting plate 240 and the inclined surface 110.

[0055] At this time, when it is necessary to clamp the track support seat 100, the supporting member 320 can be controlled to move the supporting member 320 laterally toward the inclined surface 110. Under the push of the driving member 310, the supporting member 320 moves along the inclined surface 110 toward the mounting plate 240, and finally abuts against the lower surface of the mounting plate 240 and the inclined surface 110. At this time, the track support seat 100 is clamped by the second inclined surface 110, the bottom plate 230, and the supporting member 320. It is subjected to lateral and longitudinal forces, so it has good stability. When it is necessary to adjust the position of the track support seat 100, the driving member 310 can be controlled to move in a direction away from the track support seat 100. At this time, the supporting member 320 returns to its original position, releasing the clamping of the track support seat 100, and the position of the track support seat 100 can be adjusted.

[0056] It is understandable that the material of the mounting plate 240 includes but is not limited to any one or a combination of steel, stainless steel, ceramic, high carbon steel, titanium alloy, chromium alloy, tantalum, zirconium alloy, etc. The connection method between the mounting plate 240 and the first side plate 210 includes but is not limited to any one or a combination of threaded connection, locking connection, welding connection, mortise and tenon connection, bending connection, pressure connection, adhesive connection, riveted connection, clamping connection, snap connection, one-piece molding, etc. An opening B is formed between the mounting plate 240 and the inclined surface 110. The width of the opening B should be smaller than the width of the supporting member 320, thereby preventing the supporting member 320 from sliding out of the movable groove 250. The supporting member 320 can be a slider, a cylinder, or a sphere to adapt to movable grooves 250 of different shapes. The mounting plate 240 can also be made of an integral molding process with the base 200.

[0057] For further information, please refer to Figure 3 The abutment 320 is cylindrical and can roll along the inclined surface 110. As the abutment 320 moves along the inclined surface 110 more often, the inclined surface 110 or the abutment 320 is easily worn, causing the opening B to become larger and the width of the abutment 320 to become smaller. This can cause the abutment 320 to slip out of the mounting slot, and the rail support base 100 to lose its fixation. Therefore, when the abutment 320 is cylindrical, the cylinder can roll along the inclined surface 110, and the rolling friction is less than the sliding friction, thereby reducing the wear of the abutment 320 and preventing the opening B from becoming larger.

[0058] For further information, please refer to Figure 2 and Figure 3, the axial direction of the supporting member 320 is the Y direction shown in the figure. The mounting plate 240 also includes a first folded edge 241 and a second folded edge 242 that are relatively arranged along the length direction of the movable groove 250. The supporting member 320 is located between the first folded edge 241 and the second folded edge 242. The first folded edge 241 and the second folded edge 242 are used to limit the axial movement of the supporting member 320. When the track 600 delivers the workpiece 500, axial vibration may also be generated, which may cause the supporting member 320 to deviate axially. At the same time, when the driving member 310 does not abut against the supporting member 320, the supporting member 320 may also slip out of the mounting groove due to reasons such as accidental touch. The first folded edge 241 and the second folded edge 242 provided in the present application can limit the axial movement of the supporting member 320, thereby preventing the supporting member 320 from slipping.

[0059] Specific embodiment 2 of the track locking mechanism 20 provided in the embodiment of the present application

[0060] Please refer to Figure 4 The side panels include a first side panel 210 and a second side panel 220. The first side panel 210 is inclined to the bottom panel 230 and is parallel to the inclined surface 110. The fastening assembly 300 is provided through the first side panel 210 and can move in a direction perpendicular to the inclined surface 110 and abut against the inclined surface 110. At this time, the fastening assembly 300 can be driven to move in a direction perpendicular to the inclined surface 110 to abut against or move away from the inclined surface 110. When the fastening assembly 300 abuts against the inclined surface 110, the fastening assembly 300 and the second side panel 220 clamp the track support seat 100 horizontally, and the fastening assembly 300 and the bottom panel 230 clamp the support seat longitudinally. Therefore, the track locking mechanism 20 of the embodiment of the present application has high stability.

[0061] For further information, please refer to Figure 4 A gasket 400 is further provided between the inner wall of the first side plate 210 and the inclined surface 110, and the fastening assembly 300 abuts against the gasket 400. Because the contact area between the fastening assembly 300 and the inclined surface 110 is generally small, it is easy for the fastening assembly 300 to imprint a groove on the inclined surface 110, thereby reducing the stability of the track locking mechanism 20. The track locking mechanism 20 of the embodiment of the present application adds a gasket 400 between the inner wall of the first side plate 210 and the inclined surface 110. At this time, the gasket 400 will directly contact the fastening assembly 300 instead of the inclined surface 110. Even if the gasket 400 imprints a groove, it can be quickly replaced, and its cost is relatively low. Therefore, the present application reduces the maintenance cost of the track locking mechanism 20.

[0062] It is understood that the material of the gasket 400 includes but is not limited to any one or a combination of alloys, metals, ceramics, hard plastics, composite materials, graphite, carbon fiber, etc.

[0063] Specific embodiment 3 of the track locking mechanism 20 provided in the embodiment of the present application

[0064] Please refer to Figure 5 The side panels include a first side panel 210 and a second side panel 220. The first side panel 210 is provided with a supporting surface, which is parallel to the inclined surface 110. The fastening assembly 300 is provided through the second side panel 220 and can push the track support seat 100 toward the supporting surface so that the supporting surface is in contact with the inclined surface 110. At this time, the locking structure can push the track support seat 100 toward the supporting surface laterally, so that the inclined surface 110 is in contact with and in contact with the supporting surface. At this time, the track support seat 100 is clamped laterally and longitudinally by the fastening assembly 300, the supporting surface, and the bottom plate 230, and the stability of the track locking mechanism 20 is high.

[0065] It can be understood that the above three embodiments of the track locking mechanism 20 can be mixed and used, that is, the bottom of the track support seat 100 has two opposite 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 seat 100 are clamped by the fastening components 300, and the two fastening components 300 and the bottom plate 230 jointly complete the horizontal and vertical fixation of the track support seat 100.

[0066] Please refer to Figure 1 The embodiment of the present application further provides a conveying device 10 for conveying a workpiece 500. The conveying device 10 includes the above-mentioned track locking mechanism 20. Since the conveying device 10 includes the above-mentioned track locking mechanism 20, the conveying device 10 has a simple structure and low cost.

[0067] For further information, please refer to Figure 1 The conveying device 10 includes a first rail 600, a second rail 600 and at least two rail locking mechanisms 20. The first rail 600 and the second rail 600 are arranged opposite to each other to clamp the workpiece 500; the rail locking mechanism 20 includes two rail support seats 100 and two bases 200. The two rail support seats 100 are respectively connected to the two bases 200 for clamping the first rail 600 and the second rail 600; wherein the rail support seats 100 located in different rail locking mechanisms 20 can move relative to each other to adjust the distance between the first rail 600 and the second rail 600, so that the conveying device 10 can adapt to workpieces 500 of different sizes.

[0068] The present application will be described in detail below through specific examples. The following examples are only some examples of the present application and are not limitations of the present application.

[0069] In contrast, a cross ball guide rail is used to fix the track support seat and the base.

[0070] Example A: This example provides a conveying device, which adopts the track locking mechanism provided in Example 1 of the present application, wherein the supporting member is a cylinder and the driving member is a screw.

[0071] Example B: This example provides a conveying device, which adopts the track locking mechanism provided in Example 2 of this application. The angle A is 60°, the fastening component is a screw, and a gasket is provided.

[0072] Example C: This example provides a conveying device, which adopts the track locking mechanism provided in Example 3 of the present application. The angle A is 60°, and the fastening component is a screw.

[0073] Embodiment D: This embodiment is basically the same as embodiment A, except that the angle is 45°.

[0074] The above comparative examples and embodiments were subjected to a bearing capacity test. The bearing capacity test was as follows: after tightening (rotating the screw until the screw is locked), Figure 1 Push the track support seat in the middle Y direction until the track support seat and the base move relative to each other, measure the force applied to the track support seat at this time as the bearing force, take the bearing force of the comparative example as 100%, and the bearing forces of the other embodiments are used as indicators relative to the bearing force of the comparative example.

[0075] The life test conditions are: use the conveying device to transport workpieces, and measure the offset of the position of multiple workpieces after they have completely moved through the conveying device (along the Figure 1 The average of these deviations (the degree of deviation from the preset path in the Y direction) was calculated and recorded as the base deviation. When the base deviation reached 0.1 mm, the transport duration was used as the lifespan indicator (in hours). The lifespan of the comparative example was taken as 100%, and the lifespan of the other examples relative to the comparative example was used as an indicator. The following Table 1 was obtained.

[0076] Table 1:

[0077]

[0078] According to the test results of the comparative example and embodiments A to C, the stability and service life of the three embodiments of the present application can reach a level similar to or better than that of the comparative example using a cross ball guide.

[0079] According to the test results of Examples A to C, Example B in the embodiments of the present application has the highest service life and stability among Examples A, B, and C because the force applied to its inclined surface is more uniform and the contact area between the inclined surface and the first side panel is larger.

[0080] According to the test results of Example A and Example D, it can be seen that the angle A of the inclined surface in the embodiment of the present application will affect the stability and service life of the track locking mechanism in the present application, and when the angle A is 45°, its stability and service life are higher.

[0081] In some embodiments, please refer to Figures 6 to 14 , the conveying device 10 includes a base 10, a track, a track support seat 100 and an adjustment component (not marked in the figure);

[0082] The track support base 100 carries the track, and the track support base 100 is disposed on the base 200;

[0083] The adjustment assembly is detachably connected to the track support base 100 and is used to adjust the position of the track support base 100 .

[0084] In this application, the position of the track support seat can be adjusted by means of an adjustment assembly, thereby changing the current position of the track, thereby achieving the clamping or supporting effect of the track on the workpiece. Due to the use of the adjustment assembly, this application has higher precision and efficiency than manual adjustment. At the same time, the adjustment assembly can be detachably connected to the track support seat, facilitating maintenance and replacement of the adjustment assembly.

[0085] Furthermore, when adjusting the spacing between the track support seats, if the track support seats are manually pushed to adjust the spacing between the track support seats, the adjustment efficiency of this adjustment method is low, and the accuracy of the track support seats after adjustment is low. For example, when the track support seats are connected to the base using any of the methods in the above specific embodiments one, two, and three, the friction between the track support seats and the base is sliding friction (dry friction), which makes it difficult to manually push the track support seats and ensure their accuracy. In this case, it is necessary to design an adjustment tool to adjust the distance between the track support seats.

[0086] In some embodiments, please refer to Figures 6 to 10 , Figure 1 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. In this embodiment, each track support 100 carries a track, and the track support 100 is arranged in pairs on both sides of the base 200;

[0087] The base 200 carries the track support base 100 , and the surface of the base 200 facing the track support base 100 is provided with at least one adjustment groove 260 , and the adjustment groove 260 is located in the projection area of the track support base 100 on the base 200 ;

[0088] 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;

[0089] The first connection portion 710 is disposed through the rail support base 100 . The adjustment protrusion 720 protrudes from the first connection portion 710 toward the base 200 , is located in the adjustment slot 260 , and is spaced apart from the central axis of the first connection portion 710 .

[0090] The adjustment principle of the conveying device 10 in this application is as follows: first, please refer to Figure 6 , insert the first adjusting member 700 through the track support seat 100 in the vertical direction so that the adjusting protrusion 720 is inserted into the adjusting groove 260; at this time, rotate the first connecting part 710 clockwise along its own central axis (clockwise from top to bottom). Figure 9a and Figure 9b , Figure 9a The first adjusting member 700 rotates clockwise. Due to the spacing between the adjusting protrusion 720 and the central axis of the first connecting portion 710, the first adjusting member 700 rotates eccentrically while the base 200 is stationary. Since the first adjusting member is inserted through the track support 100, the eccentric rotation of the first adjusting member 700 drives the track support 100 to move, thus achieving efficient adjustment of the spacing between adjacent track support 100 without manual movement.

[0091] It should be understood that when the length of the adjustment slot 260 is greater than the diameter of the adjustment protrusion 720, the first adjustment member 700 will no longer rotate eccentrically. Instead, the rotational motion is converted into sliding of the adjustment protrusion 720 in the adjustment slot 260, forming a type of eccentric wheel structure, that is, the rotation is converted into linear movement, thereby linearly adjusting the spacing between adjacent track support bases 100, and preventing the position of the track support bases 100 from shifting other than relative movement (movement in the front-to-back direction). At the same time, the present application converts large-scale rotation into small-scale movement, achieving precise control of the spacing between the track support bases 100.

[0092] The track support base 100 may be provided with a through hole (not marked in the figure) for the first adjusting member 700 to pass through. Figure 1 As shown, there are multiple overlapping structures in the up and down directions, so 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 multi-point force. It has high stability and is not easy to bend during the adjustment process.

[0093] For further information, please refer to Figure 6 and Figure 8The first adjusting member 700 further 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, it is typically cylindrical in shape to prevent the track support base 100 from rotating with it. However, a cylindrical shape is difficult to grip during rotation, resulting in low efficiency for workers in adjusting the track support base 100.

[0094] The present application provides a first gripping portion 730 at one end of the principle adjustment protrusion 720 of the first adjusting member 700. Since the first gripping portion 730 protrudes in a direction away from the side wall of the first connecting portion 710, the first adjusting member 700 will form a T-shaped structure. At this time, the staff can rotate the first adjusting member 700 by gripping the first gripping portion 730. It should be understood that the shape of the first connecting portion 710 can also be a square, a triangular prism, or the like, as long as the through hole on the track support base 100 through which the first connecting portion 710 passes is circular. However, in this case, the first connecting portion 710 will not be able to completely fit the side wall of the through hole. Therefore, when the first adjusting member 700 rotates, its contact surface with the track support base 100 is small, and it is easy to break.

[0095] For further information, please refer to Figure 8 The first connecting portion 710 includes a main body 711 and a head 713. One end of the main body 711 is connected to the first gripping portion 730, and the other end is provided with a snap-in groove 712. The head 713 is provided with an adjustment protrusion 720 at one end and a snap-in protrusion 714 at the other end. The snap-in protrusion 714 is inserted into the snap-in groove 712, and its shape and size are adapted to the snap-in groove 712. The size of the adjustment protrusion 720 and the distance between the adjustment protrusion 720 and the central axis of the first connecting portion 710 will affect the efficiency of the first adjusting member 700 in adjusting the distance between the track support base 100. For example, the larger the distance between the adjustment protrusion 720 and the central axis of the first connecting portion 710, the longer the distance the first adjusting member 700 can drive the track support base 100 to move per rotation. The adjusting protrusion 720 needs to be replaced according to actual needs, and the adjusting protrusion 720 is more likely to break than the first connecting portion 710 because its diameter is smaller than that of the first connecting portion 710 and it is subjected to a greater shear force.

[0096] In summary, it is necessary to design a first adjusting member 700 that is easy to replace the adjusting protrusion 720. The first connecting portion 710 in the first adjusting member 700 of the present application is divided into two parts. The main body 711 is connected to the first gripping portion 730. This part is less susceptible to force and is not easy to break. The head 713 and the main body 711 are connected by a snap-fit groove 712 and a snap-fit protrusion 714. Figure 8It can be seen that after the clamping protrusion 714 is inserted into the clamping groove 712, when the main body 711 rotates, it will drive the head 713 to rotate, thereby achieving the adjustment effect on the track support seat 100. Therefore, the present application can achieve the function of quickly adjusting the protrusion 720.

[0097] For further information, 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 portion 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 portion 710 can rotate one circle, thereby preventing the first adjusting member 700 from being stuck by the side wall of the adjusting groove 260 too early.

[0098] The adjustment protrusion 720 is cylindrical, and its diameter is equal to the width of the adjustment slot 260. If the diameter of the adjustment protrusion 720 is smaller than the width of the adjustment slot 260, then during the initial rotation of the first adjustment member 700, the adjustment protrusion 720 has not yet contacted the sidewall of the adjustment slot 260. At this time, although the first adjustment member 700 rotates, the track support base 100 cannot move, resulting in a discrepancy between the adjustment result and the intended effect. Furthermore, if the diameter of the adjustment protrusion 720 is smaller than the width of the adjustment slot 260, the first adjustment member 700 cannot effectively position the track support base 100.

[0099] Please refer to Figure 6 There are multiple adjustment slots 260, and the multiple adjustment slots 260 are arranged in sequence along the spacing direction of adjacent track support bases 100. The spacing between the track support bases 100 is usually adjusted by the first adjustment member 700 with precise control, and the adjustable distance is limited. If the distance to be adjusted is too long, multiple adjustment slots 260 can be designed to extend the length of the track support base 100 that can be adjusted by the first adjustment member 700.

[0100] For further information, please refer to Figures 6 to 13 The track support seat 100 includes a first track support seat 130 and a second track support seat 140 that are arranged opposite to each other, and the first track support seat 130 and the second track support seat 140 are both provided with tracks;

[0101] The adjustment assembly further includes a second adjustment member 800 , which includes a second connecting portion 810 , a second connecting portion 820 , and a second connecting portion 830 ;

[0102] The second connection portion 810 is provided with a thread at one end facing the second rail support base 140 and is threadedly connected to the second rail support base 140;

[0103] The second connecting part 820 is sleeved on the second connecting part 810 through the second connecting part 830, wrapping part of the second connecting part 810. The side wall of the second connecting part 820 is provided with a first annular clamping groove 821, and is passed through the first rail support seat 130. At least part of the first rail support seat 130 is clamped in the first annular clamping groove 821.

[0104] Please refer to Figure 12 and Figure 13 The working principle of the second adjusting member 800 is as follows:

[0105] First, the second adjusting member 800 is passed through the first track support seat 130 in the direction from the first track support seat 130 to the second track support seat 140, so that a portion of the first support seat 130 is located in the first annular clamping groove 821 and is clamped by the first annular clamping groove 821. Then, the second adjusting member 800 is rotated so that the end of the second adjusting member 800 with the thread is threadedly connected to the second track support seat 140. Next, the second connecting portion 820 and the second connecting portion 810 are fixedly connected via the second connecting portion 830. At this time, if the second connecting portion 810 is pulled, the first track support seat 130 and the second track support seat 140 will move synchronously. If the fixing effect of the second connecting portion 830 is released, then when the second connecting portion 810 moves, the second track support seat 140 will move, but the first track support seat 130 will not move, so the distance between the two track support seats 100 can be adjusted.

[0106] For further information, 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 clamping groove 811, and the second connecting part 820 is provided with a connecting through hole (not marked in the figure). The second connecting part 830 is passed through the connecting through hole and is at least partially located in the second annular clamping groove 811; it can be understood that in order to adapt to the first rail support seat 130 and the second rail support seat 140 with different spacings, there can be multiple second annular clamping grooves and connecting through holes.

[0107] The second adjusting member 800 further 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 sidewall of the second connecting portion 810. At this time, the second connecting portion 810 can be moved by gripping the second gripping portion 840.

[0108] For further information, please refer to Figure 6 、 Figure 13 and Figure 14 , the first rail support seat 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 portion 820 is located in the second sleeve mounting hole 120;

[0109] The diameter of the first sleeve mounting hole 110 is greater than or equal to the outer diameter of the first annular clamping groove 821 , and the diameter of the second sleeve mounting hole 120 is equal to the inner diameter of the first annular clamping groove 821 .

[0110] Because the second connecting portion 820 has a first annular snap-fit groove 821, if the size of the through-hole on the track support seat 100 is equal to the outer diameter of the first annular snap-fit groove 821, although the second connecting portion 820 can pass through the first track support seat 130, the contact area between the inner wall of the first annular snap-fit groove 821 and the first track support seat 130 will be reduced, and the second connecting portion 820 may wobble in the through-hole. Therefore, the present application designs the first sleeve mounting hole 110 for the second connecting portion 820 to pass through, and the second sleeve mounting hole 120 and the first annular snap-fit groove 821 have the same inner diameter, which can fix the second connecting portion 820 and thus prevent the second adjusting member 800 from shaking.

[0111] Accordingly, the present application further provides a wire bonding machine, which includes the above-described conveying device 10. Because the wire bonding machine includes the above-described conveying device 10, the wire bonding machine of the present application can adjust the spacing between adjacent track support bases 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 bases 100.

[0127] Comparative Example 1

[0128] This comparative example is basically the same as Example 1, except that there is no first adjusting member in the comparative example, and the position of the track support seat is adjusted by manually pushing the track support seat.

[0129] Comparative Example 2

[0130] This comparative example is substantially the same as comparative example 1, except that the fastening assembly 300 and the side plate 201 generate a horizontal preload of 500 N to vertically clamp the bottom of the base. The screw 30 and the threaded groove 270 cooperate to generate a vertical preload of 500 N to clamp the bottom of the rail support.

[0131] Measurement method

[0132] After the rail support seat moves 10mm, use the tensile gauge to pull the rail support seat in comparative example 1, record the tension displayed by the tensile gauge, and use this tension as the basic tension, which is set as 100%. Use the conveying device to convey the workpiece. After the rail support seat moves 10mm, measure the offset of the position of 50 workpieces after they have completely moved through the conveying device ( Figure 1 5 direction), calculate the average of the offset, record it as the basic offset, and record its size as 100%;

[0133] Use two tension gauges to connect the two ends of the first connecting portion of the embodiment 1 and the embodiment 3, so that the tension gauge and the first connecting portion are at right angles, and then pull the two tension gauges clockwise to drive the first adjusting member to rotate. Figure 1Rotate clockwise from top to bottom, record the sum of the values on the dynamometers of Example 1 and Example 3 when the track support starts to move, and compare this value with the tension of Comparative Example 1. After the track support moves 10 mm, measure the offset of the positions of 50 workpieces after they have completely moved through the conveying device ( Figure 5 The average of the offset is calculated and recorded as the basic offset, and its size is compared with the offset of comparative example 1;

[0134] Use two tensile gauges to connect the two ends of the second connecting part of Example 2 and Example 4, so that the tensile gauge and the first connecting part are at right angles. Then pull the tensile gauges and record the combined tensile force, and compare it with that of Comparative Example 1. After the rail support moves 10 mm, measure the offset of the position of 50 workpieces after they have completely moved through the conveying device (along the Figure 1 The degree of deviation of the Y direction from the preset path is calculated, and the average of the offset is recorded as the basic offset;

[0135] The offset of Comparative Example 1 is taken as 100%. The offsets of the remaining 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%);

[0136] According to the above experimental data, the following table is obtained:

[0137] Table 2:

[0138]

[0139]

[0140] From Table 2 we can see that:

[0141] According to Comparative Example 2, when the vertical preload force and the horizontal preload force are both greater than 500N, when the existing manual push adjustment method is used to adjust the track support seat, even if the pulling force is increased to ten times the original, the track support seat still cannot move, and the pulling force size and offset are meaningless. That is, the manual push adjustment method of the track support seat has low adjustment efficiency compared to the adjustment using tools such as the first adjustment member and the second adjustment member.

[0142] As can be seen from Examples 1 and 2 and Comparative Example 1, the use of the first and second adjusting members can reduce the force required to move the track support, resulting in a high force transmission efficiency. Furthermore, the deviation rate of the workpiece being transported after the track support is adjusted can be reduced, thereby improving the accuracy of the conveying device and the yield rate of the workpieces.

[0143] 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 to move the rail support. However, the first adjustment member requires a smaller increase in tension. While offset can easily occur due to vibration or operational errors during adjustment, the first adjustment member exhibits the smallest increase in offset, demonstrating its ability to achieve high-precision position adjustment even with high preload.

[0144] In summary, the present application can improve the adjustment accuracy and efficiency of the track spacing of the conveying device.
