Description

Product positioning device and dispensing equipment Technical Field

[0001] This utility model relates to the field of dispensing technology, and in particular to a product positioning device and dispensing equipment. Background Technology

[0002] In the manufacturing process of electronic products, dispensing is a crucial step. During dispensing, it is essential to first ensure the product is precisely positioned before the dispensing operation can be carried out accurately.

[0003] As described above, existing positioning devices for product positioning typically have two clamping blocks. The positioning device clamps and positions the product by moving the two clamping blocks relative to each other. However, during the clamping and positioning process, the relative movement of the clamping blocks can easily damage the product. Furthermore, during the dispensing process, the dispensing head needs to move horizontally to complete the dispensing operation; however, during this movement, the dispensing head is prone to colliding with the clamping blocks, resulting in damage to the dispensing head.

[0004] Therefore, the above problems urgently need to be solved. Summary of the Invention

It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0039] This embodiment provides a dispensing device, which includes a dispensing head and a product positioning device. The product positioning device is used to clamp and position a product, and the dispensing head is used to dispense adhesive onto the product clamped and positioned on the product positioning device.

[0040] Specifically, please refer to Figures 1 to 4. In this embodiment, the product positioning device includes a positioning mechanism and a driving mechanism 2. The positioning mechanism includes a clamping module, which includes a first clamping block 1111 and a second clamping block 1112 arranged opposite to each other. The first clamping block 1111 and the second clamping block 1112 can come together to clamp the product and spread out to release the product. A first spring 11111 is provided on the side of the first clamping block 1111 away from the second clamping block 1112, and a second spring 11121 is provided on the side of the second clamping block 1112 away from the first clamping block 1111.

[0041] The drive mechanism 2 includes a transmission member 21, which can move forward and push against the first clamping block 1111 and the second clamping block 1112 to move in opposite directions, thereby causing the first clamping block 1111 and the second clamping block 1112 to separate. The transmission member 21 can also move in the reverse direction and release the push. The first spring 11111 can drive the first clamping block 1111 to move toward the second clamping block 1112 when the transmission member 21 moves in the reverse direction. The second spring 11121 can drive the second clamping block 1112 to move toward the first clamping block 1111 when the transmission member 21 moves in the reverse direction. That is, the first spring 11111 and the second spring 11121 can drive the first clamping block 1111 and the second clamping block 1112 to move closer together.

[0042] Therefore, in this embodiment, the driving mechanism 2 drives the first clamping block 1111 and the second clamping block 1112 to open through the transmission member 21, thereby enabling the placement of a product between the first clamping block 1111 and the second clamping block 1112. When the first clamping block 1111 moves away from the second clamping block 1112, the first spring 11111 undergoes elastic deformation. When the second clamping block 1112 moves away from the first clamping block 1111, the second spring 11121 undergoes elastic deformation. When the transmission member 21 moves in the opposite direction, the first spring 11111... 111 and the second spring 11121 are able to recover their deformation, wherein the first spring 11111 can drive the first clamping block 1111 to move toward the second clamping block 1112 to reset the first clamping block 1111, and the second spring 11121 can drive the second clamping block 1112 to move toward the first clamping block 1111 to reset the second clamping block 1112, thereby driving the first clamping block 1111 and the second clamping block 1112 to move closer together, thereby causing the first clamping block 1111 and the second clamping block 1112 to clamp and position the product.

[0043] Based on the above description, in this embodiment, the first spring 11111 and the second spring 11121 bring the first clamping block 1111 and the second clamping block 1112 closer together to clamp the product, thereby enabling both the first clamping block 1111 and the second clamping block 1112 to make flexible contact with the product, thereby preventing the first clamping block 1111 and / or the second clamping block 1112 from damaging the product. Furthermore, since the first spring 11111 is provided on the side of the first clamping block 1111 away from the second clamping block 1112, when the dispensing head moves horizontally and collides with the first clamping block 1111, the first spring 11111 can absorb the impact force, thereby preventing the first clamping block 1111 from damaging the dispensing head. Correspondingly, since the second spring 11121 is provided on the side of the second clamping block 1112 away from the first clamping block 1111, when the dispensing head moves horizontally and collides with the second clamping block 1112, the second spring 11121 can absorb the impact force, thereby preventing the second clamping block 1112 from damaging the dispensing head.

[0044] Moreover, in this embodiment, the transmission member 21 can push the first clamping block 1111 and the second clamping block 1112 to move simultaneously, so that when the transmission member 21 moves in the opposite direction, the first clamping block 1111 and the second clamping block 1112 can be reset simultaneously, thereby achieving the centering positioning of the product.

[0045] As described above, the clamping module also includes a first transmission rod 1121 and a second transmission rod 1122. The first transmission rod 1121 and the second transmission rod 1122 are respectively connected to the first clamping block 1111 and the second clamping block 1112. The first transmission rod 1121 and the second transmission rod 1122 are respectively provided with a first spherical surface 11211 and a second spherical surface 11221. The first spherical surface 11211 and the second spherical surface 11221 are arranged opposite to each other along the arrangement direction of the first clamping block 1111 and the second clamping block 1112.

[0046] Specifically, in this embodiment, the first clamping block 1111 and the second clamping block 1112 are arranged opposite each other in the horizontal direction. A first connecting plate 1151 is connected to the side of the first clamping block 1111 away from the second clamping block 1112. A first transmission rod 1121 is installed on the side of the first connecting plate 1151 facing the first clamping block 1111 and extends along the arrangement direction of the first clamping blocks 1111 and the second clamping block 1112. A second connecting plate 1152 is connected to the side of the second clamping block 1112 away from the first clamping block 1111. A second transmission rod 1122 is installed on the side of the second connecting plate 1152 facing the second clamping block 1112 and extends along the arrangement direction of the first clamping blocks 1111 and the second clamping block 1112. Extending in the arrangement direction, the first transmission rod 1121 and the second transmission rod 1122 are coaxially arranged. The first spherical surface 11211 is disposed at the end of the first transmission rod 1121 near the second transmission rod 1122. The center of the first spherical surface 11211 is located on the axis of the first transmission rod 1121, and the first spherical surface 11211 protrudes towards the side near the second transmission rod 1122. The second spherical surface 11221 is disposed at the end of the second transmission rod 1122 near the first transmission rod 1121. The center of the second spherical surface 11221 is located on the axis of the second transmission rod 1122, and the second spherical surface 11221 protrudes towards the side near the first transmission rod 1121.

[0047] In addition, a third spherical surface 211 is provided at one end of the transmission member 21. Based on the above description, the third spherical surface 211 is located at the top of the transmission member 21 and protrudes upward. The transmission member 21 can move up and down in the vertical direction. Specifically, the drive mechanism 2 also includes a drive member 22, which is used to drive the transmission member 21 to move up and down in the vertical direction. When the transmission member 21 rises, the third spherical surface 211 can extend between the first transmission rod 1121 and the second transmission rod 1122, and simultaneously push against the first spherical surface 1121 and the second spherical surface 212. As the transmission member 21 gradually rises, the first spherical surface 11211 and the second spherical surface 11221 slide along the third spherical surface 211. The transmission member 21 applies a thrust to the first transmission rod 1121 through the third spherical surface 211 and the first spherical surface 11211, and applies a thrust to the second transmission rod 1122 through the third spherical surface 211 and the second spherical surface 11221, thereby causing the first transmission rod 1121 and the second transmission rod 1122 to move in opposite directions, which in turn drives the first clamping block 1111 and the second clamping block 1112 to move in opposite directions.

[0048] When the driving member 22 drives the transmission member 21 to descend, the third spherical surface 211 gradually exits between the first spherical surface 11211 and the second spherical surface 11221. At this time, the transmission member 21 stops applying thrust to the first transmission rod 1121 and the second transmission rod 1122. That is, the transmission member 21 releases the push on the first transmission rod 1121 and the second transmission rod 1122. Under the action of the first spring 11111 and the second spring 11121, the first clamping block 1111 and the second clamping block 1112 move closer to clamp and position the product.

[0049] It is understood that the drive component 22 can be selected as a linear drive structure such as a cylinder or an electric cylinder, and this embodiment does not impose specific restrictions on it.

[0050] For example, in this embodiment, the clamping module further includes a first mounting block 1131 and a second mounting block 1132. The first mounting block 1131 is disposed on the side of the first clamping block 1111 away from the second clamping block 1112. The first spring 11111 is installed between the first clamping block 1111 and the first mounting block 1131, so that it can be compressed and deformed when the first clamping block 1111 moves away from the second clamping block 1112, and can recover its deformation after the transmission member 21 releases the push, thereby driving the first clamping block 1111 to move toward the second clamping block 1112.

[0051] The second mounting block 1132 is located on the side of the second clamping block 1112 away from the first clamping block 1111. The second spring 11121 is installed between the second clamping block 1112 and the second mounting block 1132, so that it can be compressed and deformed when the second clamping block 1112 moves away from the first clamping block 1111, and can recover its deformation after the transmission member 21 releases the push, thereby driving the second clamping block 1112 to move toward the first clamping block 1111.

[0052] Furthermore, a first guide rod 1141 is provided on the side of the first clamping block 1111 away from the second clamping block 1112. The first guide rod 1141 extends along the arrangement direction of the first clamping block 1111 and the second clamping block 1112 and passes through the first mounting block 1131. That is, the first guide rod 1141 passes through the first mounting block 1131. It can be understood that, based on the above description, in this embodiment, the first connecting plate 1151 is installed on the end of the first guide rod 1141 away from the first clamping block 1111. That is, the first clamping block 1111 and the first connecting plate 1151 are respectively provided on both sides of the first mounting block 1131 along the axial direction of the first guide rod 1141, and the first spring 11111 is sleeved on the outer periphery of the first guide rod 1141.

[0053] Therefore, the first guide rod 1141 can provide guidance for the movement of the first clamping block 1111, thereby ensuring that the first clamping block 1111 can move stably away from or toward the second clamping block 1112.

[0054] Correspondingly, a second guide rod 1142 is provided on the side of the second clamping block 1112 away from the first clamping block 1111. The second guide rod 1142 extends along the arrangement direction of the first clamping block 1111 and the second clamping block 1112 and passes through the second mounting block 1132. That is, the second guide rod 1142 passes through the second mounting block 1132. It can be understood that, based on the above description, in this embodiment, the second connecting plate 1152 is installed at the end of the second guide rod 1142 away from the second clamping block 1112. That is, the second clamping block 1112 and the second connecting plate 1152 are respectively provided on both sides of the second mounting block 1132 along the axial direction of the second guide rod 1142, and the second spring 11121 is sleeved on the outer periphery of the second guide rod 1142.

[0055] Therefore, the second guide rod 1142 can provide guidance for the movement of the second clamping block 1112, thereby ensuring that the second clamping block 1112 can move stably away from or toward the first clamping block 1111.

[0056] It is worth noting that in this embodiment, two first guide rods 1141 are provided on the side of the first clamping block 1111 away from the second clamping block 1112. All the first guide rods 1141 are fitted with first springs 11111 on their outer periphery. This further ensures that the first clamping block 1111 can make flexible contact with the product and further prevents the first clamping block 1111 from damaging the dispensing head. Moreover, this embodiment can also ensure that the first clamping block 1111 can move more stably away from or toward the second clamping block 1112.

[0057] Of course, in other alternative embodiments, three or more first guide rods 1141 may be provided on the side of the first clamping block 1111 away from the second clamping block 1112, and a first spring 11111 is sleeved on the outer periphery of all the first guide rods 1141. This embodiment does not impose specific limitations on this.

[0058] Correspondingly, two second guide rods 1142 are provided on the side of the second clamping block 1112 away from the first clamping block 1111. All the second guide rods 1142 are fitted with second springs 11121 on their outer periphery. This further ensures that the second clamping block 1112 can make flexible contact with the product and further prevents the second clamping block 1112 from damaging the dispensing head. Moreover, this embodiment can also ensure that the second clamping block 1112 can move more stably away from or toward the first clamping block 1111.

[0059] Of course, in other alternative embodiments, three or more second guide rods 1142 may be provided on the side of the second clamping block 1112 away from the first clamping block 1111, and a second spring 11121 is sleeved on the outer periphery of all the second guide rods 1142. This embodiment does not impose specific limitations on this.

[0060] It is also worth noting that a first bushing 11411 is sleeved on the outer periphery of the first guide rod 1141, and a first mounting block 1131 is sleeved on the outer periphery of the first bushing 11411, thereby ensuring that the first guide rod 1141 can move smoothly relative to the first mounting block 1131 along its axial direction.

[0061] The second guide rod 1142 is fitted with a second bushing 11421 on its outer periphery, and the second mounting block 1132 is fitted on the outer periphery of the second bushing 11421, thereby ensuring that the second guide rod 1142 can move smoothly relative to the second mounting block 1132 along its axial direction.

[0062] Additionally, it should be noted that in other optional embodiments, the first spring 11111 may also be disposed between the first mounting block 1131 and the first connecting plate 1151, and correspondingly, the second spring 11121 may also be disposed between the second mounting block 1132 and the second connecting plate 1152. This embodiment does not impose any specific restrictions on this.

[0063] Furthermore, based on the foregoing description, the positioning mechanism includes two clamping modules. In one clamping module, the first clamping block 1111 and the second clamping block 1112 are arranged opposite each other along a first horizontal direction. In the other clamping module, the first clamping block 1111 and the second clamping block are arranged opposite each other along a second horizontal direction. The second horizontal direction is set at an angle to the first horizontal direction. For example, in this embodiment, the second horizontal direction is perpendicular to the first horizontal direction. The two clamping modules can clamp the product together, thereby positioning the product more comprehensively.

[0064] Therefore, in this embodiment, taking the first clamping module 11 and the second clamping module 12 as examples, for the first clamping module 11, the first transmission rod 1121 and the second transmission rod 1122 both extend along the first horizontal direction, and the first spherical surface 11211 and the second spherical surface 11221 are arranged opposite to each other along the first horizontal direction.

[0065] As for the second clamping module 12, the first transmission rod 1121 and the second transmission rod 1122 both extend along the second horizontal direction, and the first spherical surface 11211 and the second spherical surface 11221 are arranged opposite to each other along the second horizontal direction.

[0066] Based on the above, the third spherical surface 211 can extend between all the first transmission rods 1121 and all the second transmission rods 1122, and simultaneously push against all the first spherical surfaces 11211 and all the second spherical surfaces 11221. That is, in this embodiment, when the transmission member 21 rises, the third spherical surface 211 simultaneously contacts all the first spherical surfaces 11211 and all the second spherical surfaces 11221, and the transmission member 21 simultaneously pushes against all the first clamping blocks 1111 and all the second clamping blocks 1112 to disperse. Then, when the transmission member 21 descends, the transmission member 21 simultaneously stops applying thrust to all the first transmission rods 1121 and all the second transmission rods 1122, thereby causing all the first clamping blocks 1111 and all the second clamping blocks 1112 to converge simultaneously, thereby enabling the product to be centered and positioned.

[0067] Understandably, the product positioning device also includes a platform 3, with all first clamping blocks 1111 and all second clamping blocks 1112 positioned above the platform 3. That is, when the product is placed on top of the platform 3, all first clamping blocks 1111 and all second clamping blocks 1112 can clamp and position the product, while the drive mechanism 2, all first transmission rods 1121 and all second transmission rods 1122 are positioned below the platform 3.

[0068] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
