Technical Field

[0001] This utility model relates to the technical field of product feeding equipment, and in particular to a multi-station angle variable pitch device. Background Technology

[0002] In 3C industrial manufacturing, metal springs are frequently used for injection molding, often requiring loading. For example, in the assembly of internal components for tablets, metal springs are needed for injection molding, and loading these springs involves secondary handling. Due to varying angles and positions, multiple handling operations are necessary to achieve the required loading. These multiple handling operations are time-consuming, labor-intensive, and unstable, ultimately requiring manual intervention. This method, with its multiple handling operations, carries the risk of scratches during manual operation and cannot achieve safe and rapid processing, nor can it meet the needs of mass production. Utility Model Content

[0003] The purpose of this invention is to provide a multi-station angle variable pitch device to solve problems such as product scratches and low production efficiency caused by manual operation.

[0004] This utility model provides a multi-station angle-changing device, including an angle-changing mechanism, a fixed plate, a clamp, and a power mechanism. The angle-changing mechanism is slidably connected to the fixed plate, and the clamp is rotatably connected to the fixed plate. The clamp includes two acquiring parts for acquiring two products with different horizontally placed postures. The posture of one product after rotating 180° in the horizontal plane is the same as that of the other product. The power mechanism is used to drive the angle-changing mechanism to move along a first direction. There are multiple clamps. While the angle-changing mechanism moves along the first direction, it drives the multiple clamps to rotate, so that two acquiring parts in each clamp rotate by a certain angle, which is 30° to 120°.

[0005] In one embodiment of this utility model, the angle-changing mechanism includes a sliding component and a pitch-changing element. The sliding component includes a slide rail and a slider. The slider has a length extending along the first direction. The slide rail is fixedly connected to the fixed plate. The slider is slidably connected to the slide rail along the first direction. The pitch-changing element is fixedly connected to the slider. The power mechanism drives the slider or the pitch-changing element to move along the first direction on the slide rail. Simultaneously, the pitch-changing element drives the two acquisition parts of each clamp to rotate.

[0006] In one embodiment of this utility model, the pitch-changing component is a rack, and the driving end of the power mechanism has a first gear that meshes with the rack. The driving end of the power mechanism rotates to drive the pitch-changing component to move along the first direction.

[0023] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0024] This utility model provides a multi-station angle variable pitch device, such as Figure 1As shown, a multi-station angle-changing device in one embodiment includes an angle-changing mechanism 10, a fixed plate 20, a clamp 30, and a power mechanism 40. The angle-changing mechanism 10 is slidably connected to the fixed plate 20, and the clamp 30 is rotatably connected to the fixed plate 20. The clamp 30 includes two acquisition parts 31, which are used to acquire two products 72 with different horizontally placed postures. The posture of one product 72 after rotating 180° in the horizontal plane is the same as the posture of the other product 72. The power mechanism 40 is used to drive the angle-changing mechanism 10 to move along a first direction. There are multiple clamps 30. While the angle-changing mechanism 10 moves along the first direction, it drives multiple clamps 30 to rotate, so that the two acquisition parts 31 in each clamp 30 rotate a certain angle, which is 30° to 120°. Depending on the different production processes, the two acquisition units 31 can be set to rotate the product 72 at different angles, such as 30°, 35°, 38°, 40°, 45°, 50°, 55°, 60°, 65°, 70°, 75°, 80°, 85°, 90°, 95°, 100°, 110°, 120°, etc., and no single limit is set here.

[0025] In the multi-station angle-changing device of this utility model, by setting the angle-changing mechanism 10 to drive multiple clamps 30 to rotate, the two acquisition parts 31 in each clamp 30 rotate at a certain angle to realize the change of distance to acquire the product 72. This can realize the rapid handling of the product 72 and synchronous change of distance, reduce the number of secondary handling and manual operation, and improve production efficiency to a certain extent.

[0026] In this embodiment, the multi-station angle-variable distance device acquires two products 72 through two acquisition parts 31 of the fixture 30. One product 72, after rotating 180° in the horizontal plane, has the same posture as the other product 72. These two products 72 arranged in this posture are defined as a product group. Regardless of the direction in which the product group is arranged, this embodiment can drive the fixture 30 to rotate via the power mechanism 40 until the two acquisition parts 31 correspond to the two products 72 in the product group. Afterward, the two acquisition parts 31 acquire the corresponding two products 72. When the placement angle needs to be adjusted, the fixture 30 can be rotated via the power mechanism 40 to adjust the placement posture of the products 72. For example, the posture of the products 72 can be adjusted from an irregular state to a regular state. Therefore, the multi-station angle-variable distance device of this embodiment can acquire irregularly placed products 72 and adjust them to a regular state by driving the fixture 30 to rotate via the power mechanism 40, facilitating the placement of the products 72 and greatly improving production efficiency while reducing production costs.

[0027] Figure 2 This is a structural schematic diagram of the product rack 70 in this embodiment, as shown below. Figure 2As shown, the product rack 70 includes a central support 71 and six products 72 connected to the central support 71. The central support 71 is hexagonal and includes three intersecting connecting arms 711. The three connecting arms 711 are interconnected at their middle sections, and the included angle between any two adjacent connecting arms 711 is 60°. Each end of one connecting arm 711 is connected to a product 72, and the two products on each connecting arm 711 form a product group. Therefore, each product rack 70 includes three product groups. Figure 3 As shown, after removing the intermediate support 71, the multi-station angle-changing device uses two acquiring parts 31 in a fixture 30 to acquire two products 72 from a product group, and then transfers them to the next station, as follows: Figure 4 As shown, the power mechanism 40 drives the clamp 30 to rotate 60°, and then the two acquisition parts 31 acquire two products 72 from another product group. When it is necessary to acquire two products 72 from the next product group, the power mechanism 40 drives the clamp 30 to rotate 120° in the opposite direction to the previous rotation, so that the two acquisition parts 31 can acquire two products 72 from the last product group. Therefore, it can be seen that the six products 72 on a product rack 70 need to be transferred in three steps. In other embodiments, the number of connecting arms 711 can be 1, 2, 3, 4, 5, 6, 7, etc., and each connecting arm connects to one product 72 at both ends. The number of connecting arms 711 and the shape of the intermediate support 71 can be freely designed according to the actual situation and are not limited to the above.

[0028] For ease of description and understanding, the first direction is defined as the left and right direction.

[0029] In this embodiment, as Figure 5-6 As shown, the angle-changing mechanism 10 includes a sliding assembly 11 and a pitch-changing element 12. The sliding assembly 11 includes a slide rail 111 and a slider 112. The slider 112 has a length extending along a first direction. The slide rail 111 is fixedly connected to the fixed plate 20. The slider 112 is slidably connected to the slide rail 111 in a left-right direction. The pitch-changing element 12 is fixedly connected to the slider 112. The power mechanism 40 drives the slider 112 or the pitch-changing element 12 to move along the slide rail 111 in the first direction. Simultaneously, the pitch-changing element 12 drives the two acquisition parts 31 of each clamp 30 to rotate. Before rotation, the clamp 30 can acquire two products 72 of a product group on the product rack 70. When the power mechanism 40 starts working, it drives the pitch-changing element 12 to move left and right. Simultaneously, the pitch-changing element 12 drives the clamp 30 to rotate so that the two acquisition parts 31 rotate a certain angle above the two products of the next product group and acquire the products of the next product group.

[0030] Specifically, the pitch reducer 12 is a rack, and the drive end of the power mechanism 40 has a first gear 41 that meshes with the rack. The rotation of the drive end of the power mechanism 40 drives the first gear 41 to rotate, and the meshing of the first gear 41 with the rack drives the pitch reducer 12 to move in the left and right direction.

[0031] In this embodiment, as Figure 7 As shown, the clamp 30 also includes a second gear 32 and a first connecting member 33. The second gear 32 is fixedly connected to the first connecting member 33 and meshes with the pitch reducer 12. Both acquisition parts 31 are fixedly connected to the first connecting member 33. The power mechanism 40 drives the pitch reducer 12 to move in the left-right direction. During the movement, the pitch reducer 12 engages with the second gear 32 to drive the second gear 32 to rotate. During the rotation of the second gear, the first connecting member 33 is driven to rotate. The two acquisition parts 31 fixedly connected to the first connecting member 33 rotate synchronously, rotating a certain angle from their initial positions so that the acquisition parts 31 can grasp the product 72 in the next product group.

[0032] In this embodiment, as Figure 8 As shown, the multi-station angle pitch changing device also includes a positioning mechanism 50, which is used to limit the position of the pitch changing member 12 in the left and right directions.

[0033] Specifically, the positioning mechanism 50 includes a limiting member 51, a driving member 52, a positioning protrusion 53, a second connecting member 54, and a guide member 55. The limiting member 51 is fixedly mounted on the slider 112, and the driving member 52 is fixedly mounted on the fixed plate 20. The driving member 52 is telescopic to drive the positioning protrusion 53 closer to or further away from the limiting member 51. The limiting member 51 has a groove 511 that mates with the positioning protrusion 53. The positioning protrusion 53 is fixedly connected to the second connecting member 54, and the second connecting member 54 is fixedly connected to the driving part of the driving member 52. The driving part of the driving member 52 telescopically drives the positioning protrusion 53 closer to or further away from the limiting member 51. The guide member 55 guides the movement path of the positioning protrusion 53 and prevents the movement path of the positioning protrusion 53 from deviating during its up-and-down movement.

[0034] Specifically, there are three grooves 511, which are evenly spaced along the left and right direction. Before the multi-station angle-changing device starts working, when the fixture 30 has not yet rotated, the positioning protrusion 53 engages with the groove 511 in the middle position, that is, the positioning protrusion 53 is inserted into the groove 511 in the middle position. In this original state, the fixture 30 can pick up two products 72 from one of the product groups on the product rack 70 and can transport them to the next station. Subsequently, the drive member 52 drives the positioning protrusion 53 to move downward away from the groove 511, and the power mechanism 40 starts working to drive the variable pitch member 12 to move to the right. Simultaneously, the variable pitch member 12 drives the fixture 30 to rotate, and the two picking parts 31 of the fixture 30 rotate to the required angle. The drive member 52 drives the positioning protrusion 53 to move upward and insert into the groove 511 on the right side to complete this precision positioning and ensure that the rotation angle of the fixture 30 is accurate. After acquiring product 72, the drive unit 52 drives the positioning protrusion 53 to move downwards and leave the groove 511. Then, the power mechanism 40 reverses its operation to drive the pitch converter 12 to move to the left. Simultaneously, the pitch converter 12 drives the clamp 30 to rotate in the opposite direction. The two acquisition parts 31 of the clamp 30 rotate to the required angle. The drive unit 52 drives the positioning protrusion 53 to move upwards and insert into the groove 511 on the left side to complete the precision positioning and ensure that the rotation angle of the clamp 30 is accurate.

[0035] In this embodiment, as Figure 1 As shown, the multi-station angle variable pitch device also includes a docking seat 60, which includes a top plate 61, support columns 62 and a connecting seat 63. There are multiple support columns 62, and one end of each support column 62 is fixedly connected to the top plate 61, and the other end of each support column 62 is fixedly connected to the fixing plate 20. The second gear 32 is located between the top plate 61 and the fixing plate 20. The connecting seat 63 is fixedly installed on the top plate 61 and is used to connect the multi-axis robotic arm.

[0036] In this embodiment, the acquisition unit 31 includes a suction head 311, which is used to grasp the product 72.

[0037] In this embodiment, there may be four clamps 30, all of which are fixedly installed on the fixed plate 20 and evenly spaced. Setting multiple clamps 30 allows for synchronous pitch changes during the product 72 acquisition action, reducing the number of secondary handling operations and manual intervention, thus improving production efficiency. Of course, those skilled in the art can set the number of clamps 30 to 2, 3, 5, 6, etc., depending on the actual situation; no single limitation is made here. The pitch-changing component 12 has a length extending in the left-right direction, long enough to simultaneously drive all four clamps 30 to rotate to the desired angle.
