Description

Technical Field

[0001] This application relates to the field of parts inspection technology, and in particular to a parts inspection fixture. Background Technology

[0002] Calipers are important components of a car's braking system. When the brake pedal is pressed, the brake fluid pushes the caliper to create a piston movement, causing the two friction pads of the caliper to clamp the brake disc, thereby generating strong friction and achieving the purpose of braking and deceleration.

[0003] A caliper may include a caliper bracket, which is used to mount the caliper and support its components. The caliper bracket needs to undergo dimensional inspection before leaving the factory. Currently, operators manually handle the caliper brackets to inspect their dimensions, and then another operator receives the inspected brackets. This process requires a large number of operators, is inefficient, and carries the risk of missed inspections or mixing of different components. Utility Model Content

[0004] Some embodiments of this application provide a tooling for inspecting parts, which can meet the needs of automated inspection of parts, requires fewer operators, has high inspection efficiency, and low quality risk. The following is a description of the tooling provided in this application.

[0005] In a first aspect, embodiments of this application provide a tooling for inspecting parts, including at least one feeding conveyor belt, an inspection device, an unloading conveyor belt, and a transfer device. The inspection device is used to inspect the parts to be inspected. The feeding conveyor belt includes an outlet position, and the unloading conveyor belt includes an infeed position. The outlet position, the inspection device, and the infeed position are arranged sequentially along a first direction. The transfer device includes a first clamping device, a second clamping device, and a linkage device. The clamping end of the first clamping device is capable of at least a first movement along the first direction to switch between a first clamping position and a first placement position. When the first clamping device is in the first clamping position, it can clamp the part to be inspected located at the outlet position. When the first clamping device is in the first placement position, it can place the part to be inspected onto the inspection device. The clamping end of the second clamping device is capable of at least a second movement along the first direction to switch between a second clamping position and a second placement position. When the second clamping device is in the second clamping position, it can clamp the inspected part located on the inspection device. When the second clamping device is in the second placement position, it can place the inspected part onto the infeed position. The first clamping device is connected to the second clamping device via a linkage device, so that when the clamping end of the first clamping device makes a first movement, it triggers the clamping end of the second clamping device to make a second movement.

[0006] The aforementioned inspection fixture, through the design of a feeding conveyor belt, an inspection device, an unloading conveyor belt, and a transfer device, enables automated inspection of parts. During the inspection process, operators only need to replenish the parts to be inspected on the feeding conveyor belt in a timely manner, requiring fewer operators and meeting the need for personnel streamlining. Furthermore, the inspection fixture provided in this application synchronously and automatically transfers the parts to be inspected and the parts that have been inspected through the transfer device, and automatically unloads the parts through the unloading conveyor belt, instead of requiring operators to manually transfer and unload the parts. Therefore, it can effectively avoid problems such as missed inspections and mixed materials, thereby reducing quality risks and achieving high inspection efficiency.

[0007] In one possible implementation of the first aspect described above, the linkage device includes a mounting frame and a first translation drive, wherein a first clamping device and a second clamping device are respectively connected to one end of the mounting frame, and the other end of the mounting frame is connected to the first translation drive. The first translation drive is used to drive the mounting frame to translate along a first direction. During the translation of the mounting frame along the first direction, it can drive the clamping end of the first clamping device to perform a first movement and drive the clamping end of the second clamping device to perform a second movement.

[0008] In one possible implementation of the first aspect described above, the transfer device further includes a support plate, a feeding conveyor belt, the support plate, and a first translational drive member arranged sequentially along a second direction, which is parallel to the thickness direction of the feeding conveyor belt and perpendicular to the first direction. A groove extending along the first direction is provided on the support plate, and the groove penetrates the support plate along the second direction. A mounting bracket passes through the groove and is capable of sliding relative to the groove along the first direction. One end of the mounting bracket is located on the side of the support plate facing the feeding conveyor belt, and the other end of the mounting bracket is located on the side of the support plate facing the first translational drive member.

[0009] In this way, the layout space on both sides of the support plate can be fully utilized, improving space utilization and ensuring that the layout between the first clamping device, the second clamping device, the first translation drive and the mounting bracket is not too crowded and causes mutual interference.

[0010] In one possible implementation of the first aspect described above, the slide includes a first end and a second end disposed along a first direction. The first end of the slide is provided with a first buffer structure, and the second end of the slide is provided with a second buffer structure. When the mounting bracket slides to the first end of the slide, it elastically abuts against the first buffer structure, and when the mounting bracket slides to the second end of the slide, it elastically abuts against the second buffer structure.

[0011] The first and second buffer structures can effectively reduce the vibration and impact generated when the mounting bracket slides to the first and second ends of the slide, thereby reducing the risk of damage.

[0012] In one possible implementation of the first aspect described above, at least one feeding conveyor belt includes a first feeding conveyor belt and a second feeding conveyor belt, which are stacked sequentially along a second direction parallel to the thickness direction of the feeding conveyor belt and perpendicular to the first direction. The first feeding conveyor belt includes a first discharge position, and the second feeding conveyor belt includes a second discharge position. The first and second discharge positions extend along a third direction, and the first discharge position protrudes beyond the second discharge position along the third direction. The first clamping position includes a first position and a second position. When the clamping end of the first clamping device is in the first position, it can clamp the part to be inspected located at the first discharge position. When the clamping end of the first clamping device is in the second position, it can clamp the part to be inspected located at the second discharge position.

[0013] By designing the feeding conveyor belt as a double-layered feeding conveyor belt, it can support more parts to be inspected. Therefore, during the parts inspection process, there is no need to frequently replenish the feeding conveyor belt with parts to be inspected, saving unnecessary manpower and material resources.

[0014] In one possible implementation of the first aspect described above, the clamping end of the first clamping device is also capable of translation along a second direction and a third direction. During translation along the second direction and the third direction, the clamping end of the first clamping device is capable of switching between a first position and a second position of the first clamping position. During translation along the first direction, the second direction, and the third direction, the clamping end of the first clamping device is capable of switching between the first clamping position and a first placement position.

[0015] In one possible implementation of the first aspect described above, the first position and the first placement position are aligned in a third direction. The clamping end of the first clamping position can switch between the first position and the first placement position during translation along the first direction and the second direction. The clamping end of the first clamping position can switch between the second position and the first placement position during translation along the first direction, the second direction, and the third direction. This simplifies the movement path of the clamping end of the first clamping device between the first clamping position and the first placement position.

[0016] In one possible implementation of the first aspect described above, the first clamping device includes a first driving assembly and a first clamping member connected together. The first driving assembly is used to drive the first clamping member to translate along a second direction and a third direction. The first clamping member is the clamping end of the first clamping device. This allows the clamping end of the first clamping device to switch between a first clamping position and a first placement position, thereby enabling the transfer of the part to be inspected.

[0017] In one possible implementation of the first aspect described above, the first driving component includes a second translational driver, a third translational driver, and a fourth translational driver. The second translational driver is connected to the third translational driver, the third translational driver is connected to the fourth translational driver, and the fourth translational driver is connected to the first clamping member. Specifically, the second translational driver drives the third translational driver to translate along a third direction, and through the third and fourth translational drivers, drives the first clamping member to translate along the third direction. The third translational driver drives the fourth translational driver to translate along a second direction, and through the fourth translational driver, drives the first clamping member to translate along the second direction. The fourth translational driver drives the first clamping member to translate along the second direction.

[0018] According to the embodiments of this application, the translation of the first clamping member in the second direction is achieved by using a two-stage translation drive, namely a third translation drive and a fourth translation drive. This avoids the translation drive being too large in the second direction, thereby effectively saving layout space and reducing the cost of the drive.

[0019] In one possible implementation of the first aspect described above, the third direction is perpendicular to the first direction.

[0020] In one possible implementation of the first aspect described above, the unloading conveyor belt includes a first unloading conveyor belt and a second unloading conveyor belt. The first unloading conveyor belt is used to transport parts that pass inspection, and the second unloading conveyor belt is used to transport parts that fail inspection. The first unloading conveyor belt includes a first feeding position, and the second unloading conveyor belt includes a second feeding position. The first feeding position and the second feeding position are arranged sequentially along a fourth direction, which is perpendicular to the thickness direction of the unloading conveyor belt. The second placement position includes a third position and a fourth position. When the clamping end of the second clamping device is in the third position, parts that pass inspection can be placed in the first feeding position. When the clamping end of the second clamping device is in the fourth position, parts that fail inspection can be placed in the second feeding position.

[0021] In this way, qualified and unqualified parts can be automatically distinguished, making it easier to manage qualified and unqualified parts separately, effectively avoiding material mixing problems and reducing quality risks.

[0022] In one possible implementation of the first aspect described above, the clamping end of the second clamping device is also capable of translation along the fourth direction and the thickness direction of the unloading conveyor belt. During translation along the first direction, the fourth direction, and the thickness direction of the unloading conveyor belt, the clamping end of the second clamping device is capable of switching between a second clamping position and a second placement position. During translation along the fourth direction, the clamping end of the second clamping device is capable of switching between a third position and a fourth position of the second placement position.

[0023] In one possible implementation of the first aspect described above, the second clamping position and the third position are aligned in a fourth direction. The clamping end of the second clamping device is capable of switching between the second clamping position and the third position, at least during translation along the first direction and the thickness direction of the unloading conveyor belt. The clamping end of the second clamping device is capable of switching between the second clamping position and the fourth position, at least during translation along the first direction, the fourth direction, and the thickness direction of the unloading conveyor belt. This simplifies the movement path of the clamping end of the second clamping device between the second clamping position and the second placement position.

[0024] In one possible implementation of the first aspect described above, the clamping end of the second clamping device is also capable of rotating about an axis extending along a fifth direction, so that the part clamped by the clamping end of the second clamping device switches from a first state to a second state, wherein the fifth direction is perpendicular to the thickness direction of the unloading conveyor belt. The part includes a first support portion and a second support portion facing the unloading conveyor belt. In the first state, the first support portion and the second support portion are not coplanar; in the second state, the first support portion and the second support portion are coplanar, so that the part can be supported on the unloading conveyor belt by the first support portion and the second support portion.

[0025] Based on this, the parts can be placed stably on the unloading conveyor belt without shaking or bumping, effectively improving the conveying stability of the unloading conveyor belt.

[0026] In one possible implementation of the first aspect described above, the second clamping device includes a connected second driving assembly and a second clamping member. The second driving assembly drives the second clamping member to translate along a fourth direction and to rotate the second clamping member about an axis extending along a fifth direction. The second clamping member serves as the clamping end of the second clamping device. This allows the clamping end of the second clamping device to switch between a second clamping position and a second placement position, thereby enabling the transfer of the inspected part.

[0027] In one possible implementation of the first aspect described above, the second driving assembly includes a fifth translational drive, a sixth translational drive, and a rotary drive. The fifth translational drive is connected to the sixth translational drive, the sixth translational drive is connected to the second clamping member, and the rotary drive is connected to the second clamping member. Specifically, the fifth translational drive drives the sixth translational drive to translate along a fourth direction, and through the sixth translational drive, drives the second clamping member to translate along the fourth direction. The sixth translational drive drives the second clamping member to translate along the thickness direction of the unloading conveyor belt.

[0028] The rotary drive is used to drive the second clamping member to rotate about an axis extending along the fifth direction.

[0029] In one possible implementation of the first aspect described above, the fourth direction is perpendicular to the first direction.

[0030] In one possible implementation of the first aspect described above, the component is a caliper bracket. Attached Figure Description

[0050] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0051] This application provides a tooling for inspecting parts, which enables automated inspection of parts, requires fewer operators, has high inspection efficiency, and low quality risk. The parts can be, for example, caliper brackets, calipers, etc., and this application does not impose specific limitations. For ease of description, the following description uses a caliper bracket as an example.

[0052] Figure 1A An exemplary structure of the caliper 1 in an embodiment of this application is shown. Figure 1B according to Figure 1A A perspective view of the caliper bracket 11 in an embodiment of this application is shown. Figure 1C according to Figure 1A A side view of the caliper bracket 11 in an embodiment of this application is shown. (Reference) Figures 1A to 1C The caliper 1 may include a caliper bracket 11, which may include a first part 111, two second parts 112 and two third parts 113.

[0053] Specifically, the first part 111 can be used to support a friction plate in the caliper 1, and the first part 111 is also used for fixed connection with other components to realize the installation of the caliper 1. Exemplarily, the first part 111 can be generally U-shaped, and the first part 111 can include two side walls 111a and a bottom wall 111b. The two side walls 111a extend generally along direction A and are arranged opposite each other along direction B, and directions A and B can be perpendicular to each other. The bottom wall 111b extends generally along direction B and is connected between the two side walls 111a.

[0054] The two second portions 112 can be used to support another friction plate in the caliper 1. The two second portions 112 are respectively positioned opposite the first portion 111 along direction C, which can be perpendicular to directions A and B. Furthermore, one second portion 112 is connected to one sidewall 111a of the first portion 111 via a third portion 113, and the other second portion 112 is connected to another sidewall 111a of the first portion 111 via another third portion 113, thereby allowing the caliper bracket 11 to... Figure 1C From the side view shown, the overall structure resembles an inverted U-shape.

[0055] To ensure the product quality of the caliper bracket 11 and to prevent the first part 111 of the caliper bracket 11 from interfering with other components (e.g., brake disc) and causing abnormal noise after the caliper 1 is installed, it is necessary to test the thickness of the first part 111 of the caliper bracket 11. The thickness of the first part 111 can be, for example, the dimension D1 of the first part 111 along the C direction.

[0056] Currently, the dimension D1 of the first part 111 of the caliper bracket 11 needs to be manually inspected. Specifically, firstly, the operator manually removes the caliper bracket 11 to be inspected from the raw material box containing multiple caliper brackets 11. Then, the operator places the caliper bracket 11 to be inspected on the inspection device. After the inspection is completed, the inspected caliper bracket 11 is removed from the inspection device and passed to the next operator.

[0057] Based on the above testing methods, it is clear that each caliper bracket 11 requires at least two operators for testing and transport, resulting in a large number of personnel needed. Furthermore, as the number of tests increases, operator fatigue is inevitable, leading to lower testing efficiency and the possibility of missed tests or material mixing, thus posing a higher quality risk.

[0058] In view of this, this application provides a testing fixture that can replace operators to achieve automated testing of caliper brackets, requiring fewer operators, effectively improving testing efficiency and reducing quality risks. The following is a detailed description with reference to the accompanying drawings.

[0059] Figure 2A and Figure 2B A perspective view of the detection fixture 10 in an embodiment of this application is shown, wherein, for ease of observation, Figure 2A and Figure 2B Also shown is the caliper bracket 11. (Reference) Figure 2A and Figure 2B The inspection fixture 10 may include at least one feeding conveyor belt 100, an inspection device 200, an unloading conveyor belt 300, and a transfer device 400.

[0060] The feeding conveyor belt 100 may include a discharge position O1, which is the position where the caliper bracket 11 to be tested is removed from the feeding conveyor belt 100. This is the end point where the feeding conveyor belt 100 transports the caliper bracket 11 to be tested. The unloading conveyor belt 300 may include a feeding position I1, which is the position where the caliper bracket 11 that has been tested is placed onto the unloading conveyor belt 300. This is the starting point where the unloading conveyor belt 300 begins to carry the caliper bracket 11 that has been tested. The discharge position O1, the testing device 200, and the feeding position I1 are arranged sequentially along the X direction (as an example of the first direction).

[0061] The transfer device 400 can transfer the caliper bracket 11 to be tested at the discharge position O1 of the loading conveyor belt 100 to the testing device 200 for testing, and simultaneously transfer the caliper bracket 11 that has been tested on the testing device 200 to the feeding position I1 of the unloading conveyor belt 300, so as to achieve synchronous loading and unloading.

[0062] Specifically, the transfer device 400 may include a first clamping device 410, a second clamping device 420, and a linkage device 430.

[0063] The clamping end 411 of the first clamping device 410 is capable of a first movement along the X direction, so as to... Figure 2A The first clamping position N1 shown is N1 and Figure 2B The device switches between the first placement positions M1 shown. When the clamping end 411 of the first clamping device 410 is in the first clamping position N1, it can clamp the caliper bracket 11 to be tested located at the discharge position O1 of the feeding conveyor belt 100; when the clamping end 411 of the first clamping device 410 is in the first placement position M1, it can place the caliper bracket 11 to be tested on the detection device 200 so that the detection device 200 can detect the caliper bracket 11. For example, the detection device 200 can be used to detect the caliper bracket 11 in... Figure 1C Dimension D1 in the illustrated embodiment.

[0064] The clamping end 421 of the second clamping device 420 is capable of a second movement at least along the X direction, so as to... Figure 2A The second clamping position N2 shown is... Figure 2BThe device switches between the second placement position M2 shown. When the clamping end 421 of the second clamping device 420 is in the second clamping position N2, it can clamp the caliper bracket 11 that has completed inspection on the inspection device 200; when the clamping end 421 of the second clamping device 420 is in the second placement position M2, it can place the caliper bracket 11 that has completed inspection at the feeding position I1 of the unloading conveyor belt 300. The unloading conveyor belt 300 can transport the caliper bracket 11 to other places for other operations. For example, the unloading conveyor belt 300 can transport the qualified caliper bracket 11 to a certain position so that the caliper bracket 11 can be packaged and shipped.

[0065] The first clamping device 410 is connected to the second clamping device 420 via a linkage device 430, so that when the first clamping device 410 makes a first movement, it can trigger the second clamping device 420 to make a second movement. That is to say, the action of the first clamping device 410 to transfer the caliper bracket 11 to be tested and the action of the second clamping device 420 to transfer the caliper bracket 11 after the test is completed are performed synchronously.

[0066] The aforementioned testing fixture 10, through the design of a feeding conveyor belt 100, a testing device 200, a discharging conveyor belt 300, and a transfer device 400, enables automated testing of the caliper bracket 11. During the testing process of the caliper bracket 11, operators only need to replenish the caliper brackets 11 to be tested on the feeding conveyor belt 100 in a timely manner, requiring fewer operators and meeting the need for personnel streamlining. Furthermore, the testing fixture 10 provided in this application synchronously and automatically transfers the caliper brackets 11 to be tested and the caliper brackets 11 that have been tested through the transfer device 400, and automatically discharges them through the discharging conveyor belt 300, instead of requiring operators to manually transfer and discharge the caliper brackets 11. Therefore, it can effectively avoid problems such as missed testing and mixed materials, thereby reducing quality risks and achieving high testing efficiency.

[0067] It should be noted that the term "connected" in the above-mentioned connection of the first clamping device 410 and the second clamping device 420 via the linkage device 430 can be a mechanical connection or an electrical connection; it can be a fixed connection, a detachable connection, or an integral connection. This application does not limit this, and any linkage device 430 that can cause the first movement of the first clamping device 410 to trigger the second movement of the second clamping device 420 is within the protection scope of this application.

[0068] The specific structure of the linkage device 430 will be described below with reference to the accompanying drawings.

[0069] Specifically, Figure 3A A perspective view of the linkage device 430 in the transfer device 400 of this application embodiment is shown. Figure 3BA side view of the transfer device 400 in an embodiment of this application is shown for easy observation. Figure 3A and Figure 3B The portion of mounting bracket 432 that is obscured is shown by dashed lines. Figure 3B The location of the feeding conveyor belt 100 is also indicated by a dashed line. (Reference) Figure 3A and Figure 3B The linkage device 430 may include a first translation drive 431 and a mounting bracket 432. The first translation drive 431 is used to drive the mounting bracket 432 to translate along the X direction.

[0070] The first clamping device 410 and the second clamping device 420 are respectively connected to the first end 432a (as an example of one end of the mounting frame 432) of the mounting frame 432, and the second end 432b (as an example of the other end of the mounting frame 432) is connected to the first translation drive member 431. That is, the first clamping device 410, the second clamping device 420 and the first translation drive member 431 are connected as a whole through the mounting frame 432. In this way, when the mounting frame 432 is driven to translate along the X direction by the first translation drive member 431, it can drive the clamping end 411 of the first clamping device 410 to make a first movement, and drive the clamping end 421 of the second clamping device 420 to make a second movement, thereby causing the first movement of the first clamping device 410 to trigger the second movement of the second clamping device 420.

[0071] In some embodiments of this application, the first translation drive 431 can be any one of a pneumatic cylinder or an electric cylinder. This application does not impose specific restrictions on this, as long as the above-mentioned driving function can be achieved.

[0072] Continue reading Figure 3A and Figure 3B To support the first clamping device 410, the second clamping device 420, and the linkage device 430, in some embodiments of this application, the transfer device 400 may further include a support plate 440. The first translational drive member 431 of the feeding conveyor belt 100, the support plate 440, and the linkage device 430 is arranged sequentially along the Z direction (as an example of the second direction), which is parallel to the thickness direction of the feeding conveyor belt 100 and perpendicular to the X direction.

[0073] The support plate 440 may have a groove 441 extending in the X direction. The groove 441 extends through the support plate 440 in the Z direction. The mounting bracket 432 of the linkage device 430 passes through the groove 441 and can slide relative to the groove 441 in the X direction. The first end 432a of the mounting bracket 432 is located on the side of the support plate 440 facing the feeding conveyor belt 100, and is used to connect with the first clamping device 410 and the second clamping device 420. The second end 432b of the mounting bracket 432 is located on the side of the support plate 440 facing the first translation drive member 431, so as to facilitate connection with the first translation drive member 431. That is, the first clamping device 410 and the second clamping device 420 are mounted on one side of the support plate 440 through the mounting bracket 432, and the first translation drive member 431 is mounted on the other side of the support plate 440. In this way, the layout space on both sides of the support plate 440 can be fully utilized to improve space utilization, so that the layout between the first clamping device 410, the second clamping device 420, the first translation drive member 431 and the mounting bracket 432 will not be too crowded and cause mutual interference.

[0074] Continue reading Figure 3A In some embodiments of this application, the slide 441 may include a first end 441a and a second end 441b, the first end 441a and the second end 441b are arranged along the X direction, and the mounting bracket 432 can slide between the first end 441a and the second end 441b of the slide 441 along the Z direction.

[0075] The slide 441 may have a first buffer structure 450 at its first end 441a and a second buffer structure 460 at its second end 441b. When the mounting bracket 432 slides to the first end 441a of the slide 441, it can elastically abut against the first buffer structure 450; when the mounting bracket 432 slides to the second end 441b of the slide 441, it can elastically abut against the second buffer structure 460. The first buffer structure 450 and the second buffer structure 460 can effectively reduce the vibration and impact generated when the mounting bracket 432 slides to the first end 441a and the second end 441b of the slide 441, thereby reducing the risk of damage.

[0076] In some implementations, the first buffer structure 450 and the second buffer structure 460 can be springs, elastic pads, hydraulic buffer structures or pneumatic buffer structures, etc. This application does not impose specific restrictions on them, as long as they can achieve the buffering effect.

[0077] It should be noted that the above Figures 2A to 3BIn the illustrated embodiment, the movement of the clamping end 411 of the first clamping device 410 and the clamping end 421 of the second clamping device 420 is not limited to translation along the X direction. Due to different structural designs of the feeding conveyor belt 100, the clamping end 411 of the first clamping device 410 can also move in other directions. Similarly, due to different structural designs of the unloading conveyor belt 300, the second clamping device 420 can also move in other directions. The movements of the clamping end 411 of the first clamping device 410 and the clamping end 421 of the second clamping device 420 along other directions will be described below with reference to the accompanying drawings.

[0078] To facilitate understanding, before introducing the movement of the clamping end 411 of the first clamping device 410, the structure of the feeding conveyor belt 100 will be introduced in conjunction with the accompanying drawings.

[0079] Figure 4 An exemplary structure of the feeding conveyor belt 100 in an embodiment of this application is shown. (See reference...) Figure 4 In some embodiments of this application, the feeding conveyor belt 100 is a double-layer conveyor belt, including a first feeding conveyor belt 110 and a second feeding conveyor belt 120. The first feeding conveyor belt 110 and the second feeding conveyor belt 120 can be stacked sequentially along the Z-direction. The first feeding conveyor belt 110 is the lower layer conveyor belt, and the second feeding conveyor belt 120 is the upper layer conveyor belt. The surface of the first feeding conveyor belt 110 used to carry the caliper bracket 11 to be tested faces the second feeding conveyor belt 120 along the Z-direction, while the surface of the second feeding conveyor belt 120 used to carry the caliper bracket 11 to be tested faces away from the first feeding conveyor belt 110 along the Z-direction.

[0080] By designing the feeding conveyor belt 100 as a double-layer feeding conveyor belt, the feeding conveyor belt 100 can support more caliper brackets 11 to be tested. Therefore, during the testing of caliper brackets 11, it is not necessary to frequently replenish the feeding conveyor belt 100 with caliper brackets 11 to be tested, saving unnecessary manpower and material resources.

[0081] Continue reading Figure 4In some implementations, since the feeding conveyor belt 100 is a double-layer conveyor belt, the discharge position O1 of the feeding conveyor belt 100 can include two positions. Specifically, the first feeding conveyor belt 110 can include a first discharge position O11, and the second feeding conveyor belt 120 can include a second discharge position O12. The first discharge position O11 and the second discharge position O12 extend along the Y direction (as an example of the third direction), and the Y direction is perpendicular to the X direction. Furthermore, along the Y direction, the first discharge position O11 protrudes beyond the second discharge position O12. That is, when observing along the Z direction from the side of the second feeding conveyor belt 120 opposite to the first feeding conveyor belt 110, the first discharge position O11 and the second discharge position O12 can be observed simultaneously, and the first discharge position O11 is not obstructed by the second discharge position O12. In this way, the first clamping device 410 can smoothly clamp the caliper bracket 11 to be tested located at the first discharge position O11 and the second discharge position O12.

[0082] In this embodiment, the Y direction is used as an example of a third direction, but this application is not limited thereto. In other embodiments, the third direction and the X direction may also be parallel to each other or have a certain angle between them. For example, the third direction and the X direction may have an angle of 10°, 20° or 30°.

[0083] Similarly, in some implementations, since the feeding conveyor belt 100 is a double-layer conveyor belt, the feeding position I2 of the feeding conveyor belt 100 can also include two positions. Specifically, the first feeding conveyor belt 110 can include a first feeding position I21, which is the position where the caliper bracket 11 to be tested is placed on the first feeding conveyor belt 110, marking the starting point for the first feeding conveyor belt 110 to carry the caliper bracket 11 to be tested. The second feeding conveyor belt 120 can also include a second feeding position I22, which is the position where the caliper bracket 11 to be tested is placed on the second feeding conveyor belt 120, marking the starting point for the second feeding conveyor belt 120 to carry the caliper bracket 11 to be tested.

[0084] The first feeding position I21 and the second feeding position I22 can each extend along the Y direction. Furthermore, along the Y direction, the first feeding position I21 protrudes beyond the second feeding position I22. That is, when observing along the Z direction from the side of the second feeding conveyor belt 120 opposite to the first feeding conveyor belt 110, both the first feeding position I21 and the second feeding position I22 can be observed simultaneously, and the first feeding position I21 will not be obstructed by the second feeding position I22. This allows the operator to smoothly replenish the caliper bracket 11 to be tested to both the first feeding position I21 and the second feeding position I22.

[0085] Based on the above Figure 4In the embodiment shown, the first discharge position O11 and the second discharge position O12, and the first clamping position N1 corresponding to the first clamping device 410 may also include two positions.

[0086] Specifically, Figure 5A according to Figure 4 This illustration shows a schematic diagram of the first clamping device 410 located at a first position N11 in the first clamping position N1 according to an embodiment of this application. Figure 5B according to Figure 4 A schematic diagram is shown of the first clamping device 410 in the embodiment of this application, located at the second position N12 of the first clamping position N1.

[0087] refer to Figure 5A and Figure 5B The first clamping position N1 may include a first position N11 and a second position N12. The first position N11 corresponds to the first discharge position O11 of the first feeding conveyor belt 110. When the clamping end 411 of the first clamping device 410 is located at the first position N11, it can clamp the caliper bracket 11 to be tested located at the first discharge position O11. The second position N12 corresponds to the second discharge position O12 of the second feeding conveyor belt 120. When the clamping end 411 of the first clamping device 410 is located at the second position N12, it can clamp the caliper bracket 11 to be tested located at the second discharge position O12.

[0088] In some embodiments of this application, the clamping end 411 of the first clamping device 410 can alternately clamp the caliper bracket 11 to be tested at the first discharge position O11 and the second discharge position O12. In this way, the consumption of the caliper bracket 11 to be tested on the first feeding conveyor belt 110 and the second feeding conveyor belt 120 can be approximately the same, so as to facilitate material replenishment.

[0089] Based on the above Figure 5A and Figure 5B In some embodiments of this application, the clamping end 411 of the first clamping device 410 can also translate along the Y and Z directions, as shown in the first position N11 and the second position N12 in the illustrated embodiment.

[0090] During translation along the Y and Z directions, the clamping end 411 of the first clamping device 410 can switch between a first position N11 and a second position N12 of the first clamping position N1, thereby clamping the caliper bracket 11 to be tested located at the first discharge position O11 and the second discharge position O12. For example, in Figure 5A In the example shown, the clamping end 411 of the first clamping device 410 located at the first position N11 can first translate upward along the Z direction, and then translate to the left along the Y direction, thereby moving to the second position N12.

[0091] The clamping end 411 of the first clamping device 410 is in the X direction (e.g., Figure 5A and Figure 5B During the translation in the direction perpendicular to the paper (Y direction and Z direction), it can switch between the first clamping position N1 and the first placement position (not shown). The first clamping position N1 includes a first position N11 and a second position N12.

[0092] For example, Figure 6A according to Figure 5A This illustration shows a schematic diagram of the clamping end 411 of the first clamping device 410 in an embodiment of this application switching between a first position N11 of the first clamping position N1 and a first placement position M1. Figure 6B according to Figure 5B This illustration shows a schematic diagram of the clamping end 411 of the first clamping device 410 in an embodiment of this application switching between a second position N12 of the first clamping position N1 and a first placement position M1.

[0093] refer to Figure 6A In some implementations, the first position N11 of the first clamping position N1 can be aligned with the first placement position M1 in the Y direction. Thus, during translation along the X and Z directions, the clamping end 411 of the first clamping device 410 can switch between the first position N11 of the first clamping position N1 and the first placement position M1, thereby transferring the caliper bracket 11 to be inspected at the first discharge position O11 to the inspection device 200. The clamping end 411 of the first clamping device 410 does not need to translate along the Y direction, and the movement path of the clamping end 411 of the first clamping device 410 is simpler. It should be noted that... Figure 6A From the perspective shown, a portion of the clamping end 411 of the first clamping device 410 and the caliper bracket 11 to be tested at the first discharge position O11 are obscured by the second feeding conveyor belt 120.

[0094] For example, in Figure 6A In the example shown, after the clamping end 411 of the first clamping device 410 located at the first position N11 clamps the caliper bracket 11 to be tested, it can first move upward along the Z direction, and then move closer to the detection device 200 along the X direction. After moving to above the detection device 200, it can then move downward along the Z direction to the first placement position M1 shown by the dashed line, so as to place the caliper bracket 11 to be tested on the detection device 200.

[0095] refer to Figure 6BDuring the translation along the X, Y and Z directions, the clamping end 411 of the first clamping device 410 can switch between the second position N12 of the first clamping position N1 and the first placement position M1, thereby transferring the caliper bracket 11 to be tested located at the second discharge position O12 to the testing device 200.

[0096] For example, in Figure 6B In the example shown, after the clamping end 411 of the first clamping device 410 located at the second position N12 clamps the caliper bracket 11 to be tested, it can first translate upward along the Z direction, and then translate along the Y direction to align with the first placement position M1 in the Y direction. After that, it translates along the X direction to the top of the detection device 200, and finally translates downward along the Z direction to the first placement position M1 shown by the dashed line, so as to place the caliper bracket 11 to be tested on the detection device 200.

[0097] It is understandable that the above Figure 6A and Figure 6B This illustration merely schematically shows the movement path of the clamping end 411 of the first clamping device 410 and does not constitute a limitation of this application. For example, in some alternative implementations, the second position N12 of the first clamping position N1 may be aligned with the first placement position M1 in the Y direction. This would simplify the movement path of the clamping end 411 of the first clamping device 410 between the first clamping position N1 and the first placement position M1.

[0098] Continue reading Figures 5A to 6B To enable the clamping end 411 of the first clamping device 410 to translate in the Y and Z directions, in some embodiments of this application, the first clamping device 410 may include a first driving component 412 and a first clamping member 413, which are connected together. The first driving component 412 drives the first clamping member 413 to translate along the Y and Z directions, and the first clamping member 413 is the clamping end 411 of the first clamping device 410. This allows the clamping end 411 of the first clamping device 410 to switch between a first clamping position N1 and a first placement position M1, thereby enabling the transfer of the caliper bracket 11 to be tested.

[0099] In some embodiments of this application, the first driving assembly 412 may include a second translational drive 4120, a third translational drive 4121, and a fourth translational drive 4122. The second translational drive 4120 is connected to the third translational drive 4121, the third translational drive 4121 is connected to the fourth translational drive 4122, and the fourth translational drive 4122 is connected to the first clamping member 413. Specifically, the second translational drive 4120 drives the third translational drive 4121 to translate along the Y direction, and through the third and fourth translational drive 4121 and fourth translational drive 4122, drives the first clamping member 413 to translate along the Y direction. The third translational drive 4121 drives the fourth translational drive 4122 to translate along the Z direction, and through the fourth translational drive 4122, drives the first clamping member 413 to translate along the Z direction. The fourth translational drive 4122 drives the first clamping member 413 to translate along the Z direction.

[0100] Since the first position N11 and the second position N12 of the first clamping position N1 have a height difference in the Z direction, the displacement stroke of the first clamping member 413 in the Z direction is relatively large. The translation of the first clamping member 413 in the Z direction is realized by a two-stage translation drive, namely the third translation drive 4121 and the fourth translation drive 4122. This can avoid the translation drive being too large in the Z direction, thereby effectively saving layout space and reducing the cost of the drive.

[0101] In some implementations, the second translation drive 4120, the third translation drive 4121, and the fourth translation drive 4122 can be either a pneumatic cylinder or an electric cylinder. This application does not impose specific restrictions on this, as long as the above-mentioned driving function can be achieved.

[0102] It is understandable that the above Figures 4 to 6B The illustrated embodiment is merely a schematic representation of the structure of the feeding conveyor belt 100 and does not constitute a limitation of this application. In other embodiments, the feeding conveyor belt 100 may also be a conveyor belt with fewer or more layers, such as one, three, four, or five layers.

[0103] After describing the movement of the feeding conveyor belt 100 and the corresponding clamping end 411 of the first clamping device 410, the movement of the unloading conveyor belt 300 and the corresponding clamping end 421 of the second clamping device 420 will be described below with reference to the accompanying drawings.

[0104] Figure 7 An exemplary structure of the unloading conveyor belt 300 in an embodiment of this application is shown, with the caliper bracket 11 indicating completion of inspection indicated by dashed lines. Reference Figure 7In some embodiments of this application, the unloading conveyor belt 300 may include a first unloading conveyor belt 310 and a second unloading conveyor belt 320. The first unloading conveyor belt 310 is used to transport caliper brackets 11 that have passed inspection, and the second unloading conveyor belt 320 is used to transport caliper brackets 11 that have failed inspection. This allows for automatic differentiation between caliper brackets 11 that have passed and those that have failed inspection, facilitating separate management of these brackets and effectively preventing material mixing and reducing quality risks.

[0105] Continue reading Figure 7 In some implementations, since the unloading conveyor belt 300 includes two conveyor belts, the feeding position I1 of the unloading conveyor belt 300 can include two positions. Specifically, the first unloading conveyor belt 310 can include a first feeding position I11, and the second unloading conveyor belt 320 can include a second feeding position I12. The first feeding position I11 and the second feeding position I12 can be arranged sequentially along the Y direction (as an example of a fourth direction).

[0106] In this embodiment, the Y direction is used as an example of the fourth direction, that is, the fourth direction is perpendicular to the X direction, but this application is not limited to this. In other embodiments, the fourth direction can also be other directions perpendicular to the thickness direction of the unloading conveyor belt 300 (e.g., the Z direction). For example, the fourth direction can also be parallel to the X direction or have a certain angle with it. For example, the fourth direction and the X direction can have an angle of 10°, 20° or 30°.

[0107] Based on the above Figure 7 In the embodiment shown, the first feeding position I11 and the second feeding position I12, and the second placement position M2 corresponding to the second clamping device 420 may also include two positions.

[0108] Specifically, Figure 8 according to Figure 7 This illustration shows a schematic diagram of the second clamping device 420 located at the third position M21 and the fourth position M22 of the second placement position M2 in an embodiment of this application. (See reference...) Figure 8 The second placement position M2 may include a third position M21 and a fourth position M22. The third position M21 corresponds to the first feeding position I11 of the first unloading conveyor belt 310. When the clamping end 421 of the second clamping device 420 is located at the third position M21, a qualified caliper bracket 11 can be placed at the first feeding position I11. The fourth position M22 corresponds to the second feeding position I12 of the second unloading conveyor belt 320. When the clamping end 421 of the second clamping device 420 is located at the fourth position M22, a failed caliper bracket 11 can be placed at the second feeding position I12.

[0109] Based on the above Figure 8 In some embodiments of this application, the clamping end 421 of the second clamping device 420 can also translate along the Y and Z directions, as shown in the third position M21 and the fourth position M22 in the illustrated embodiment.

[0110] The clamping end 421 of the second clamping device 420 can switch between the third position M21 and the fourth position M22 of the second placement position M2, at least during translation along the Y direction. This allows for the placement of a qualified caliper bracket 11 at the first feeding position I11 and a failed caliper bracket 11 at the second feeding position I12. For example, in... Figure 8 In the example shown, the clamping end 421 of the second clamping device 420, which is located at the first feeding position I11 (shown by the dashed line), can be translated to the left along the Y direction, thereby moving to the second feeding position I12 (shown by the solid line).

[0111] The clamping end 421 of the second clamping device 420 is at least along the X direction (e.g., Figure 8 During the translation in the direction perpendicular to the paper, the Y direction, and the Z direction, it is possible to switch between the second clamping position (not shown) and the second placement position M2. The second placement position M2 includes the third position M21 and the fourth position M22.

[0112] For example, Figure 9A according to Figure 8 This illustration shows a schematic diagram of the clamping end 421 of the second clamping device 420 in an embodiment of this application switching between the second clamping position N2 and the third position M21 of the second placement position M2. Figure 9B according to Figure 8 This illustration shows a schematic diagram of the clamping end 421 of the second clamping device 420 in an embodiment of this application switching between the second clamping position N2 and the fourth position M22 of the second placement position M2.

[0113] refer to Figure 9A In some implementations, the third position M21 of the second placement position M2 can be aligned with the second clamping position N2 in the Y direction. Thus, the clamping end 421 of the second clamping device 420 can switch between the second clamping position N2 and the third position M21 of the second placement position M2, at least during translation along the X and Z directions, thereby transferring the qualified caliper bracket 11 located in the detection device 200 to the first feeding position I11 of the first unloading conveyor belt 310. The clamping end 421 of the second clamping device 420 does not need to translate along the Y direction, and the movement path of the clamping end 421 of the second clamping device 420 is simpler.

[0114] For example, in Figure 9AIn the example shown, after the clamping end 421 of the second clamping device 420 located at the second clamping position N2 clamps the qualified caliper bracket 11, it can first move upward along the Z direction, and then move along the X direction to approach the first feeding position I11 of the first feeding conveyor belt 310. After moving to above the first feeding position I11, it moves downward along the Z direction to the third position M21 of the second placement position M2 shown by the dashed line, so as to place the qualified caliper bracket 11 in the first feeding position I11.

[0115] refer to Figure 9B The clamping end 421 of the second clamping device 420 can switch between the second clamping position N2 and the fourth position M22 of the second placement position M2 during translation at least along the X, Y and Z directions, thereby transferring the unqualified caliper bracket 11 located in the detection device 200 to the second feeding position I12 of the second unloading conveyor belt 320.

[0116] For example, in Figure 9B In the example shown, after clamping the caliper bracket 11 that failed the inspection, the clamping end 421 of the second clamping device 420 located at the second clamping position N2 can first move upward along the Z direction, and then move upward along the Y direction to align with the fourth position M22 of the second placement position 2 in the Y direction. Then, it moves upward along the X direction to above the second feeding position I12, and finally moves downward along the Z direction to the fourth position M22 of the second placement position M2 shown by the dashed line, so as to place the caliper bracket 11 that failed the inspection in the second feeding position I12.

[0117] It is understandable that the above Figure 9A and Figure 9B This illustration merely schematically shows the movement path of the clamping end 421 of the second clamping device 420 and does not constitute a limitation of this application. For example, in some alternative implementations, the fourth position M22 of the second placement position M2 may be aligned with the second clamping position N2 in the Y direction. This would simplify the movement path of the clamping end 421 of the second clamping device 420 between the second clamping position N2 and the second placement position M2.

[0118] In some embodiments of this application, the clamping end 421 of the second clamping device 420 can also be rotated so that the caliper bracket 11 can be stably placed at the feeding position I1 of the unloading conveyor belt 300.

[0119] Specifically, Figure 10A and Figure 10B This diagram illustrates the rotation of the clamping end 421 of the second clamping device 420 in an embodiment of this application. (See reference) Figure 10A and Figure 10BIn some embodiments of this application, the clamping end 421 of the second clamping device 420 can be rotated around the X direction (e.g., along the X direction). Figure 10A and Figure 10B Rotate the axis extending perpendicular to the paper plane (as an example of the fifth direction) so that the caliper bracket 11 held by the clamping end 421 of the second clamping device 420 can be rotated by Figure 10A The first state shown has switched to Figure 10B The second state is shown. For example, the rotation direction of the clamping end 421 of the second clamping device 420 can be... Figure 10A and Figure 10B In the D direction, the rotation center of the clamping end 421 of the second clamping device 420 can be, for example, Figure 10A and Figure 10B Point Q1 in the middle.

[0120] The caliper bracket 11 may include a first support portion 114 and a second support portion 115. In a first state, the first support portion 114 and the second support portion 115 are not coplanar; in a second state, the first support portion 114 and the second support portion 115 are coplanar. For example, the first support portion 114 and the second support portion 115 may be located in plane F1. When the caliper bracket 11 is placed on the unloading conveyor belt 300, the first support portion 114 and the second support portion 115 can serve as two fulcrums, allowing the caliper bracket 11 to be supported on the unloading conveyor belt 300. Therefore, the caliper bracket 11 can be placed stably on the unloading conveyor belt 300 without shaking or bumping, effectively improving the conveying stability of the unloading conveyor belt 300.

[0121] In this embodiment, the X direction is used as an example of the fifth direction, but this application is not limited to this. In other embodiments, the fifth direction can also be other directions perpendicular to the Z direction, such as the Y direction, or the fifth direction can have a certain angle with the X direction, such as 10°, 20° or 30° between the fifth direction and the X direction.

[0122] In some of these implementations, the first support portion 114 of the caliper bracket 11 may be, for example, Figure 1C In the illustrated embodiment, the first portion 111 protrudes from one end of the third portion 113, and the second support portion 115 may be, for example, Figure 1C The corner where the second part 112 and the third part 113 connect in the illustrated embodiment. In some other implementations, the first support portion 114 and the second support portion 115 of the caliper bracket 11 may also be other structures, and this application does not impose specific limitations on them.

[0123] Continue reading Figures 8 to 10BTo enable the clamping end 421 of the second clamping device 420 to translate in the Y and Z directions and rotate about an axis extending along the X direction, in some embodiments of this application, the second clamping device 420 may include a second driving assembly 422 and a second clamping member 423, which are connected together. The second driving assembly 422 drives the second clamping member 423 to translate in the Y and Z directions and to rotate about an axis extending along the X direction. The second clamping member 423 is the clamping end 421 of the second clamping device 420. This allows the clamping end 421 of the second clamping device 420 to switch between a second clamping position N2 and a second placement position M2, thereby enabling the transfer of the caliper bracket 11 after detection.

[0124] In some embodiments of this application, the second driving assembly 422 may include a fifth translational drive 4220, a sixth translational drive 4221, and a rotational drive 4222. The fifth translational drive 4220 is connected to the sixth translational drive 4221, the sixth translational drive 4221 is connected to the second clamping member 423, and the rotational drive 4222 is also connected to the second clamping member 423. Specifically, the fifth translational drive 4220 drives the sixth translational drive 4221 to translate along the Y direction, and through the sixth translational drive 4221, drives the second clamping member 423 to translate along the Y direction. The sixth translational drive 4221 drives the second clamping member 423 to translate along the Z direction. The rotational drive 4222 drives the second clamping member 423 to rotate about an axis extending along the X direction.

[0125] Continue to refer to Figure 10A and Figure 10B In some implementations, the second clamping member 423 may include a first end 423a and a second end 423b, which are arranged along the Y direction. The first end 423a of the second clamping member 423 may be rotatably connected to the sixth translational drive member 4221, and the second end 423b of the second clamping member 423 may be rotatably connected to the rotational drive member 4222. The rotational drive member 4222 may also be fixedly connected to the sixth translational drive member 4221. The rotational drive member 4222 may extend and retract along the Z direction, thereby pushing the second end 423b of the second clamping member 423 to move along the Z direction, thereby causing the second clamping member 423 to rotate about an axis extending along the X direction with the first end 423a as the rotation center. That is, the first end 423a coincides with point Q1.

[0126] In some implementations, the fifth translation drive 4220, the sixth translation drive 4221, and the rotation drive 4222 can be either a pneumatic cylinder or an electric cylinder. This application does not impose specific restrictions on this, as long as the above-mentioned driving function can be achieved.

[0127] After introducing the feeding conveyor belt 100, the unloading conveyor belt 300 and the transfer device 400, the exemplary structure of the detection device 200 will now be described in conjunction with the accompanying drawings.

[0128] Figure 11 A perspective view of the detection device 200 in an embodiment of this application is shown. (See reference) Figure 11 In this embodiment of the application, the detection device 200 can be used to detect the thickness of the caliper bracket 11. Figure 1C In the illustrated embodiment, corresponding to dimension D1, the detection device 200 may include a base 210, a positioning component 220, and a displacement sensor component 230.

[0129] The base 210 supports the positioning assembly 220 and the displacement sensor assembly 230, providing a fixed support. The positioning assembly 220 secures the caliper bracket 11, ensuring its stability during measurement. For example, in... Figure 11 In the example shown, when the caliper bracket 11 is placed on the detection device 200, the positioning component 220 can translate along the Y direction to clamp the caliper bracket 11, thereby fixing the caliper bracket 11 to the detection device 200. After the caliper bracket 11 is fixed to the detection device 200, the displacement sensor component 230 can begin to detect the position of the caliper bracket 11 on the detection device 200. Figure 1C Dimension D1 in the illustrated embodiment.

[0130] Understandable. Figure 11 This illustration merely represents one structural form of the detection device 200 and does not constitute a limitation of this application. In other embodiments, the detection device 200 may also detect other parameters of the caliper bracket 11 or other parts, and correspondingly, the components included in the detection device 200 may differ.

[0131] The above description illustrates the implementation of this application through specific embodiments. Those skilled in the art can easily understand other advantages and effects of this application from the content disclosed in this specification. Although the description of this application is presented in conjunction with some embodiments, this does not mean that the features of this application are limited to these embodiments, and this application can also be implemented without using these details.
