[0078] To make the technical problems solved, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0079] like Figures 1 to 11As shown, the material conveying device 10 provided in this embodiment of the present invention includes a platform 1 and multiple material conveying mechanisms 2. Each material conveying mechanism 2 includes a first conveying drive assembly 21, a second conveying drive assembly 22, and a conveying tray 23. The conveying tray 23 is used to carry material 20. The first conveying drive assembly 21 and the second conveying drive assembly 22 are respectively installed on the platform 1, and the first conveying drive assembly 21 and the second conveying drive assembly 22 are respectively connected to the conveying tray 23 in a transmission manner. The first conveying drive assembly 21 cooperates with the second conveying drive assembly 22 to drive the conveying tray 23 to reciprocate between the material transfer position and the test position along a first direction x.

[0080] At the material transfer position, material 20 can be placed onto or removed from the conveyor tray 23. At the test position, the material 20 on the conveyor tray 23 can be detected.

[0081] Multiple material conveying mechanisms 2 are sequentially arranged on platform 1 along the second direction z. The first direction x and the second direction z are not parallel and not collinear.

[0082] The material conveying device 10 provided in this embodiment of the present invention employs a dual-drive structure consisting of a first conveying drive component 21 and a second conveying drive component 22 for larger materials 20. This enables the conveying pallet 23 to move along the first direction x, allowing the conveying pallet 23 to move more stably to the material transfer position or the testing position. When the conveying pallet 23 is in the material transfer position, the material 20 can be placed on the conveying pallet 23 or removed from the conveying pallet 23. When the conveying pallet 23 is in the testing position, the material 20 on the conveying pallet 23 can be detected by a detection device or processed by a processing device. The material conveying device 10 can alternately convey multiple materials 20 through multiple material conveying mechanisms 2 to improve work efficiency.

[0083] It should be noted that in the material conveying device 10 provided in this embodiment of the present invention, multiple material conveying mechanisms 2 refer to at least two material conveying mechanisms 2.

[0084] In one embodiment, such as Figure 1 As shown, platform 1 is a marble platform.

[0085] For larger materials 20, a marble platform is used as the base, which has shock resistance and thermal stability, and can improve the rigidity and stability of the motion system, thereby achieving stable support for the material 20 transport device.

[0086] In one embodiment, such as Figure 1 As shown, the second direction z is the height direction. At this time, the conveying trays 23 of multiple material conveying mechanisms 2 will be arranged sequentially at intervals along the height.

[0087] In one embodiment, such as Figure 1 As shown, the first direction x and the second direction z are perpendicular to each other, which can prevent mutual interference between the conveying pallets 23 when each conveying pallet 23 moves along the first direction x.

[0088] In one embodiment, such as Figure 1 As shown, the material transfer positions of each conveyor pallet 23 are arranged sequentially at intervals along the second direction z. When all conveyor pallets 23 are in the material transfer position, each conveyor pallet 23 will be positively aligned along the second direction z.

[0089] The test positions of each conveyor tray 23 are set sequentially at intervals along the second direction z. When all conveyor trays 23 are in the test positions, they will be aligned along the second direction z.

[0090] In one embodiment, such as Figure 2 As shown, platform 1 includes a first mounting beam 11, a second mounting beam 12, and a mounting base plate 13. The first mounting beam 11 and the second mounting beam 12 are arranged opposite each other along a third direction y. The mounting base plate 13 connects the first mounting beam 11 and the second mounting beam 12, and the first mounting beam 11 and the second mounting beam 12 are located on the same side of the mounting base plate 13 along a second direction z. The third direction y, the second direction z, and the first direction x are all perpendicular to each other.

[0091] The first conveying drive assembly 21 is installed on the first mounting beam 11, and the second conveying drive assembly 22 is installed on the second mounting beam 12, so that the first conveying drive assembly 21 and the second conveying drive assembly 22 are installed on the platform 1. Since the first mounting beam 11 and the second mounting beam 12 are located on the same side of the mounting base plate 13 along the second direction z, the conveying tray 23 connected to the first conveying drive assembly 21 and the second conveying drive assembly 22 can be more stable.

[0092] In one embodiment, such as Figure 2 As shown, the first mounting beam 11 includes multiple first-step mounting portions 111, which are sequentially connected along a third direction y. The second mounting beam 12 includes multiple second-step mounting portions 121, which are sequentially connected along a third direction y. The multiple first-step mounting portions 111 and the multiple second-step mounting portions 121 are arranged in a one-to-one correspondence along a second direction z.

[0093] The first conveying drive assembly 21 and the second conveying drive assembly 22 of the same material conveying mechanism 2 are respectively installed on the corresponding first step mounting part 111 and second step mounting part 121.

[0094] Therefore, both the first mounting beam 11 and the second mounting beam 12 adopt a stepped structure to achieve a layered layout of multiple material conveying mechanisms 2 and improve the conveying efficiency of materials 20.

[0095] In one embodiment, such as Figure 2 As shown, the distance between the corresponding first stepped mounting portion 111 and second stepped mounting portion 121, which are closer to the mounting base plate 13, is smaller, so that the side of the first mounting beam 11 facing the second mounting beam 12 is stepped, and the side of the second mounting beam 12 facing the first mounting beam 11 is stepped, realizing a layered layout of multiple material conveying mechanisms 2. Correspondingly, the dimension of the material conveying mechanism 2 along the third direction y is smaller the closer it is to the mounting base plate 13.

[0096] In one embodiment, with Figure 1 and Figure 2 In the embodiment shown, there are two material conveying mechanisms 2, namely a first material conveying mechanism 2a and a second material conveying mechanism 2b.

[0097] At this time, there are two first step mounting parts 111, namely the first mounting part 111a and the second mounting part 111b, and the second mounting part 111b is installed between the first mounting part 111a and the mounting base plate 13.

[0098] The second step mounting part 121 is provided in two parts, namely the third mounting part 121a and the fourth mounting part 121b. The fourth mounting part 121b is installed between the third mounting part 121a and the mounting base plate 13.

[0099] The first mounting portion 111a and the third mounting portion 121a are respectively arranged along the second direction z, and the second mounting portion 111b and the fourth mounting portion 121b are respectively arranged along the second direction z. The distance between the second mounting portion 111b and the fourth mounting portion 121b is smaller than the distance between the first mounting portion 111a and the third mounting portion 121a, so as to form a stepped structure.

[0100] The first conveying drive assembly 21 of the first material conveying mechanism 2a is installed in the first mounting part 111a, and the second conveying drive assembly 22 of the first material conveying mechanism 2a is installed in the third mounting part 121a, so that the first conveying drive assembly 21 and the second conveying drive assembly 22 of the first material conveying mechanism 2a are respectively installed in the corresponding first mounting part 111a and third mounting part 121a.

[0101] The first conveying drive assembly 21 of the second material conveying mechanism 2b is installed in the second mounting part 111b, and the second conveying drive assembly 22 of the second material conveying mechanism 2b is installed in the fourth mounting part 121b, so that the first conveying drive assembly 21 and the second conveying drive assembly 22 of the second material conveying mechanism 2b are respectively installed in the corresponding second mounting part 111b and fourth mounting part 121b.

[0102] In other embodiments not shown in the figure, the material conveying mechanism may also be provided in other numbers, such as three or five. In this case, the number of first-step mounting parts and the number of second-step mounting parts are consistent with the number of material conveying mechanisms, and the first-step mounting parts correspond one-to-one with the material conveying mechanism, and the second-step mounting parts correspond one-to-one with the material conveying mechanism. Thus, each material conveying mechanism corresponds to one first-step mounting part and one second-step mounting part.

[0103] In one embodiment, such as Figures 1 to 3 As shown, the first mounting beam 11, the second mounting beam 12 and the mounting base plate 13 are integrally formed to form an integrated platform 1.

[0104] Compared to a split design, a one-piece molding can better improve the rigidity and stability of the motion system, thereby achieving stable support for the material transport device.

[0105] In one embodiment, such as Figure 1 and Figure 2 As shown, the first conveying drive assembly 21 includes a first conveying linear motor 211. The first conveying linear motor 211 includes a first stator 2111 and a first mover 2112. The first stator 2111 is mounted on the platform 1 along a first direction x, and the first mover 2112 is connected to the conveying tray 23. The conveying tray 23 moves relative to the platform 1 by directly driving the conveying tray 23 through the first conveying linear motor 211. In other embodiments not shown in the figure, the first conveying linear motor can also be replaced by other linear actuators such as cylinders.

[0106] In other embodiments not shown in the figure, the first conveying drive assembly may further include a first conveying transmission structure, which is connected to the first mover and the conveying tray so that the first mover drives the conveying tray to move in a first direction through the first conveying transmission structure, thereby driving the conveying tray.

[0107] In one embodiment, such as Figure 1 and Figure 2 As shown, the second conveying drive assembly 22 includes a second conveying linear motor 221. The second conveying linear motor 221 includes a second stator 2211 and a second mover 2212. The second stator 2211 is mounted on the platform 1 along a first direction x, and the second mover 2212 is connected to the conveying tray 23. The movement of the conveying tray 23 relative to the platform 1 is achieved by directly driving the conveying tray 23 through the second conveying linear motor 221. In other embodiments not shown in the figure, the second conveying linear motor can also be replaced by other linear actuators such as cylinders.

[0108] In other embodiments not shown in the figures, the second conveying drive assembly may further include a second conveying transmission structure, which is tractively connected between the second mover and the conveying tray, so that the second mover drives the conveying tray to move in the first direction through the second conveying transmission structure, thereby driving the conveying tray.

[0114] It should be noted that, in Figures 1 to 11In the embodiment shown with two material conveying mechanisms 2, for ease of distinction, the conveying tray 23 of the first material conveying mechanism 2a is labeled as 23a, and the conveying tray 23 of the second material conveying mechanism 2b is labeled as 23b. The structures of the first clamping drive assembly 232, the second clamping drive assembly 233, the first clamping assembly 234, and the second clamping assembly 235 of the conveying trays 23a and 23b are identical. The difference between the tray frames 231 of the conveying trays 23a and 23b is that their widths along the third direction y are different, in order to adapt to the installation positions on the platform 1.

[0117] When adjusting the distance between the first clamping assembly 234 and the second clamping assembly 235, the first clamping drive member 2321 and the second clamping drive member 2331 can work synchronously, thereby causing the first clamping drive rod 2322 and the second clamping drive rod 2332 to rotate synchronously, thereby driving the first clamping assembly 234 and the second clamping assembly 235 to move closer to or further away from each other.

[0118] In one embodiment, the first clamping drive 2321 may be a drive motor, or it may be a rotary cylinder or other structure that can achieve rotary drive.

[0128] By sliding the first clamping unit 23421 relative to the first clamping base plate 2341 along the third direction y, and by sliding the second clamping unit relative to the second clamping base plate along the third direction y, the positions of each first clamping unit 23421 and each second clamping unit along the third direction y can be adjusted to accommodate materials 20 of different lengths.

[0129] In one embodiment, such as Figure 7 and Figure 8 As shown, the first clamping assembly 234 further includes a first engaging member 2343, which is mounted on the first clamping base plate 2341 along a third direction y. The first clamping component 2342 further includes a first engaging unit 23422, which is connected to the first clamping unit 23421. The first engaging unit 23422 has a first engaged state and a first unlocked state.

[0130] In the first engaged state, the first engaging unit 23422 engages with the first engaging member 2343. In the first unlocked state, the first engaging unit 23422 disengages from the first engaging member 2343.

[0131] When the first engaging unit 23422 is in the first engaging state, the first engaging unit 23422 engages with the first engaging member 2343, and the first clamping unit 23421 is fixed relative to the first clamping base plate 2341; when the first engaging unit 23422 is in the first unlocking state, the first engaging unit 23422 disengages from the first engaging member 2343, so that the first engaging unit 23422 can slide relative to the first clamping base plate 2341 along the third direction y, thereby adjusting the position of the first engaging unit 23422 along the third direction y to adapt to materials 20 of different lengths.

[0134] When the second meshing unit is in the second meshing state, the second meshing unit meshes with the second meshing member, and the second clamping unit is fixed relative to the second clamping base plate; when the second meshing unit is in the second unlocking state, the second meshing unit disengages from the second meshing member, allowing the second meshing unit to slide relative to the second clamping base plate along the third direction y, thereby adjusting the position of the second meshing unit along the third direction y to accommodate materials 20 of different lengths.

[0135] In one embodiment, such as Figure 7 and Figure 8 As shown, the first engagement unit 23422 includes a first connecting plate 234221, a first pressing plate 234222, a first engagement component 234223, and a first elastic component 234224.

[0137] In its initial shape, the first pressing plate 234222, under the elastic force of the first elastic member 234224, presses the first engaging member 234223 against the first engaging member 2343, so that the first engaging member 234223 engages with the first engaging member 2343, and the position of the first clamping unit 23421 relative to the first clamping base plate 2341 is fixed.

[0138] When the first pressing plate 234222 is pressed, the first elastic element 234224 can undergo elastic deformation, causing the first engaging element 234223 to move away from the first engaging element 2343, thereby disengaging the first engaging element 234223 from the first engaging element 2343, allowing the first clamping unit 23421 to slide relative to the first clamping base plate 2341 along the third direction y, thereby adjusting the position of the first clamping unit 23421 along the third direction y.

[0142] When the second pressing plate is pressed, the second elastic element can undergo elastic deformation, causing the second engaging element to move away from the second engaging element, thereby disengaging the second engaging element from the second engaging element, allowing the second clamping unit to slide relative to the second clamping base plate along the third direction y, thereby adjusting the position of the second clamping unit along the third direction y.

[0143] In one embodiment, such as Figure 8 As shown, the first engaging member 2343 is a first rack, and the first engaging mating member 234223 is a second rack.

[0157] Since the test fixture includes an upper mold and a lower mold (i.e., the first fixture and the second fixture), and the first fixture and the second fixture are opposite each other along the second direction z, the position of the conveying tray 23 of the first material conveying mechanism 2a relative to the test fixture can be obtained by having the positioning component 24 of the first material conveying mechanism 2a take a picture and position the first fixture. Similarly, the position of the conveying tray 23 of the second material conveying mechanism 2b relative to the test fixture can be obtained by having the positioning component 24 of the second material conveying mechanism 2b take a picture and position the second fixture.

At the testing position, the material 20 on the conveyor tray 23 can be tested by the testing device 50.

[0160] Material 20 is a PCB board.

[0161] The PCB board testing equipment provided in this novel embodiment, for materials 20 of a larger size, employs a platform 1 as a base for stable support of the material 20 transport device. It also utilizes a dual-drive structure consisting of a first conveying drive assembly 21 and a second conveying drive assembly 22 to move the conveying tray 23 along the first direction x, enabling the conveying tray 23 to move more stably to the material transfer position or the testing position. When the conveying tray 23 is in the material transfer position, materials 20 can be placed on or removed from the conveying tray 23.
