Description

Technical Field

[0001] This invention belongs to the field of electronic product assembly technology, and particularly relates to a clamping and positioning device. Background Technology

[0002] In the assembly process of electronic products, such as smartwatches, smart bands, and mobile phones, components need to be placed inside the product's casing for positioning before being secured. Currently, this is mainly done manually, placing the components inside the casing for positioning and then securing them using methods such as adhesive application, welding, or screws. Because the space inside the casing is limited, positioning the components is extremely inconvenient, severely affecting positioning accuracy. Furthermore, it's crucial to prevent the components from shifting position during securing, making assembly quite difficult. Summary of the Invention

[0003] The purpose of this invention is to provide a clamping and positioning device that aims to solve the problems of low positioning accuracy and high assembly difficulty in manually assembled parts.

[0004] This invention discloses a clamping and positioning device, which includes a support structure, a product fixing seat fixedly installed on the support structure, a slide block slidably installed on the support structure along a direction close to / away from the product fixing seat, and a sliding drive mechanism for driving the slide block to slide. A positioning plug for fixing and installing components is provided on the slide block. The device also includes a clamping structure corresponding to the positioning plug and inserted into the product fixing seat, and a clamping drive mechanism for driving the clamping structure to slide along the sliding direction of the slide block.

[0005] As an improvement, the product mounting base includes a base fixed to the support structure, a cover plate for fastening onto the base, forming an accommodating space between the cover plate and the base, and a detachable connecting structure disposed between the cover plate and the base; an insertion channel corresponding to the positioning plug is provided between the cover plate and the base, and a window area communicating with the accommodating space is provided on the cover plate, and the clamping structure passes through the window area and is inserted into the accommodating space.

[0006] As an improvement, a rotating connection mechanism is provided between the corresponding sides of the cover plate and the base, and the detachable connection structure is provided between the cover plate and the side of the base away from the rotating connection mechanism.

[0007] As an improvement, the clamping structure is slidably mounted on the cover plate, the clamping structure extends through the window area to the side near the base, the clamping drive mechanism is fixedly mounted on the cover plate, and the output part of the clamping drive mechanism is fixedly connected to the clamping structure.

[0008] As an improvement, the fixed connection between the clamping drive mechanism, the clamping structure, and the output of the clamping drive mechanism is located on the side of the window area away from the rotating connection mechanism.

[0009] As an improvement, the detachable connection structure is a spring-loaded hook and loop or a magnetic connection.

[0010] As an improvement, a pressure plate is fixedly installed on the slide above the positioning plug. When the sliding drive mechanism drives the slide and the positioning plug to slide and transport the parts through the insertion channel into the product to be assembled, the pressure plate presses against the cover plate to form a limit.

[0011] As an improvement, the slide includes a main body slidably mounted on the support structure, a first seat body slidably mounted on the main body in a vertical direction, a first adjustment structure for adjusting the vertical position of the first seat body, and a second seat body slidably mounted on the first seat body in a horizontal direction, and a second adjustment structure for adjusting the horizontal position of the second seat body. The sliding direction of the main body is perpendicular to the sliding direction of the first seat body and the sliding direction of the second seat body. The positioning plug and the pressure plate are respectively fixedly mounted on the second seat body.

[0012] As an improvement, a CCD detection mechanism facing the insertion channel is fixedly installed on the support structure, the slide is disposed on the side of the product fixing seat and the CCD detection mechanism, the slide is fixedly installed with a support plate extending between the product fixing seat and the CCD detection mechanism, and the positioning plug is fixedly installed on the support plate.

[0013] As an improvement, the sliding drive mechanism and the clamping drive mechanism are configured as manual quick clamps.

[0014] As a result of the above technical solution, the clamping and positioning device of the present invention includes a support structure, a product fixing seat fixedly installed on the support structure, a slide block slidably installed on the support structure along the direction of approaching / away from the product fixing seat, and a sliding drive mechanism for driving the slide block to slide. A positioning plug for fixing and installing components is provided on the slide block. It also includes a clamping structure corresponding to the positioning plug and inserted into the product fixing seat, and a clamping drive mechanism for driving the clamping structure to slide along the sliding direction of the slide block.

[0015] During assembly, the product to be assembled is fixed to the product fixing base, and the components are fixed to the positioning plug. The sliding drive mechanism drives the slide and the positioning plug to slide, accurately feeding the components into the product to be assembled and moving the components to the assembly position. Then, the clamping drive mechanism drives the clamping structure to slide towards the positioning plug, clamping the components between the clamping structure and the positioning plug. The components are then fixed inside the product by dispensing glue, welding, or screws. The components can be accurately fed into the product to be assembled and clamped between the clamping structure and the positioning plug, avoiding movement of the components during fixing and affecting the positioning accuracy. This solves the problems of low positioning accuracy and high assembly difficulty in manual assembly. Attached Figure Description

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of this invention clearer, the invention 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 and not intended to limit the invention.

Figure 2 A three-dimensional structural schematic diagram (I) of the clamping and positioning device according to an embodiment of the present invention is shown.

For ease of description, only the parts related to the present invention are shown in the figure.

[0022] It should be noted that if the present invention involves directional indications (such as up, down, front, back, left, right, etc.), the directional indications are only used to explain the relative positional relationship between the components in a specific posture. If the specific posture changes, the directional indications will also change accordingly. If the present invention involves descriptions such as "first", "second", etc., the descriptions such as "first", "second", etc. are only for descriptive purposes and should not be construed as indicating or implying their relative importance or implicitly indicating the number of technical features indicated.

[0023] like Figure 1 , Figure 2 and Figure 3 As shown, an embodiment of the present invention discloses a clamping and positioning device, including a support structure 10, a product fixing seat 20 fixedly installed on the support structure 10, a slide block 30 slidably installed on the support structure 10 along the direction of approaching / away from the product fixing seat 20, and a sliding drive mechanism 40 for driving the slide block 30 to slide. A positioning plug 31 for fixing and installing parts is provided on the slide block 30 for inserting the parts to be assembled into the product fixing seat 20. It also includes a clamping structure 50 corresponding to the positioning plug 31 and inserted into the product fixing seat 20, and a clamping drive mechanism 60 for driving the clamping structure 50 to slide along the sliding direction of the slide block 30.

[0024] During assembly, the product to be assembled is fixed to the product fixing base 20, and the parts are fixed to the positioning plug 31. The sliding drive mechanism 40 drives the slide 30 and the positioning plug 31 to slide, accurately feeding the parts into the product to be assembled and moving the parts to the assembly position. Then, the clamping drive mechanism 60 drives the clamping structure 50 to slide towards the positioning plug 31, clamping the parts between the clamping structure 50 and the positioning plug 31. The parts are fixed to the product by dispensing glue, welding or screws. The parts can be accurately fed into the product to be assembled and can be clamped between the clamping structure 50 and the positioning plug 31, avoiding movement during fixing of the parts and affecting the positioning accuracy. This solves the problems of low positioning accuracy and high assembly difficulty in manual assembly of parts.

[0025] In this embodiment of the invention, the product fixing base 20 includes a base 21 fixed to the support structure 10, a cover plate 22 for fastening onto the base 21, forming an accommodating space between the cover plate 22 and the base 21, and a detachable connecting structure disposed between the cover plate 22 and the base 21; an insertion channel is provided on one side of the positioning plug 31 between the cover plate 22 and the base 21, and a window area 23 communicating with the accommodating space is provided on the cover plate 22, and the clamping structure 50 passes through the window area 23 and is inserted into the accommodating space.

[0026] Specifically, a rotating connection mechanism is provided between the corresponding sides of the cover plate 22 and the base 21. A detachable connection structure is provided between the sides of the cover plate 22 and the base 21 away from the rotating connection mechanism. After the cover plate 22 is fastened to the base 21, the cover plate 22 and the base 21 can be fixedly connected to achieve the fixation of the product to be assembled, and avoid the position of the product to be assembled from changing during assembly, which would affect the assembly accuracy.

[0027] For ease of operation, the clamping structure 50 is slidably mounted on the cover plate 22. The clamping structure 50 extends through the window area 23 towards the side near the base 21. The clamping drive mechanism 60 is fixedly mounted on the cover plate 22, and the output part of the clamping drive mechanism 60 is fixedly connected to the clamping structure 50. Since both the clamping structure 50 and the clamping drive mechanism 60 are located on the cover plate 22, when the cover plate 22 is flipped, the clamping structure 50 and the clamping drive mechanism 60 move synchronously with the cover plate 22. During assembly, the cover plate 22 is opened first, then the product to be assembled is placed on the base 21, and then the cover plate 22 is closed. Since the clamping structure 50 extends through the window area 23 towards the side of the base 21, after the cover plate 22 is closed, the clamping structure 50 is inserted into the product to be assembled.

[0028] Typically, the fixed connection between the clamping drive mechanism 60, the clamping structure 50, and the output of the clamping drive mechanism 60 is located on the side of the window area 23 away from the rotating connection mechanism, so as to avoid interference with the surrounding structure when the cover plate 22 is flipped away from the base 21.

[0029] like Figure 2 As shown, the detachable connection structure is a spring buckle 24. In some other embodiments, the detachable connection structure can also be set as a magnetic structure, which is fixed by magnetic attraction.

[0030] In this embodiment of the invention, the slide 30 includes a main body slidably mounted on the support structure 10, a first seat body slidably mounted on the main body in a vertical direction (vertical direction refers to the direction perpendicular to the base 21), a first adjustment structure for adjusting the vertical position of the first seat body, and a second seat body slidably mounted on the first seat body in a horizontal direction (horizontal direction refers to the direction parallel to the platform of the support structure 10), a second adjustment structure for adjusting the horizontal position of the second seat body, and a positioning plug 31 fixedly mounted on the second seat body; the sliding direction of the main body is perpendicular to the sliding direction of the first seat body and the sliding direction of the second seat body.

[0031] Since the second base is slidably mounted on the first base in the horizontal direction and the positioning plug 31 is fixedly mounted on the second base, the vertical position of the first base can be adjusted by the first adjustment structure to adjust the vertical position of the positioning plug 31. At the same time, the horizontal position of the second base can be adjusted by the second adjustment structure to adjust the horizontal position of the positioning plug 31, so that the positioning plug 31 is aligned with the assembly position inside the product to be assembled, thereby further improving the assembly accuracy.

[0032] Specifically, the main seat is slidably mounted on the support structure via a guide rail slider assembly. A vertical groove is provided on the main seat, and a first seat is slidably mounted on the vertical groove. A vertical baffle is provided at the upper end of the vertical groove. The first adjustment structure is a first microhead 32, which is fixed vertically to the vertical baffle. The rod of the first microhead 32 passes through the vertical baffle and is fixedly connected to the first seat. By rotating the first microhead 32 in the forward or reverse direction, the rod can extend or retract, thereby driving the first seat to slide. A horizontal groove is provided on the first seat, and a second seat is slidably mounted on the horizontal groove. A horizontal baffle is provided at the end of the horizontal groove away from the positioning plug 31. The second adjustment structure is a second microhead 33, which is fixed horizontally to the horizontal baffle. The rod of the second microhead 33 passes through the horizontal baffle and is fixedly connected to the second seat. By rotating the second microhead 33 in the forward or reverse direction, the rod can extend or retract, thereby driving the second seat to slide.

[0033] Of course, the first base can also be slidably mounted on the main base via the guide rail slider assembly, and the second base can also be slidably mounted on the first base via the guide rail slider assembly.

[0034] In some other embodiments, the slide 30 may also be configured as a manual XY translation stage, with the positioning plug 31 fixed to the moving part of the manual XY translation stage.

[0035] The structures of the first differential head 32, the second differential head 33, and the manual XY translation stage in this embodiment of the invention are known technologies, and their specific structures and usage methods will not be described in detail here.

[0036] To prevent the cover plate 22 from accidentally opening during component assembly, a pressure plate 70 is fixedly installed on the slide 30 above the positioning plug 31. When the sliding drive mechanism 40 drives the slide 30 and the positioning plug 31 to slide and transport the component through the insertion channel into the product to be assembled, the pressure plate 70 presses against the cover plate 22 to form a limit. Specifically, the cover plate 22 is fixedly installed on the second base and moves synchronously with the positioning plug 31.

[0037] In this embodiment of the invention, a CCD detection mechanism 80 facing the insertion channel is fixedly installed on the support structure 10, a slide 30 is disposed on the side of the product fixing seat 20 and the CCD detection mechanism 80, a support plate 311 extending between the product fixing seat 20 and the CCD detection mechanism 80 is fixedly installed on the slide 30, and a positioning plug 31 is fixedly installed on the support plate 311.

[0038] The slide 30 is located on the side of the product mounting base 20 and the CCD detection mechanism 80. On the one hand, it can reduce the distance between the CCD detection mechanism 80 and the product mounting base 20, and on the other hand, it can prevent the slide 30 from affecting the shooting of the CCD detection mechanism 80.

[0039] In this embodiment of the invention, the sliding drive mechanism 40 and the clamping drive mechanism 60 are configured as manual quick clamps. Specifically, the structure of the manual quick clamp is a known technology, and its specific structure will not be described in detail here.

[0040] In some other embodiments, the sliding drive mechanism 40 and the clamping drive mechanism 60 may also be configured as an electric cylinder or a pneumatic cylinder.

[0041] The above description is merely some embodiments of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
