Description

Technical Field

[0001] This invention relates to the field of refrigerator assembly tooling technology, specifically a positioning clamp device adapted to refrigerator shelf assembly strips. Background Technology

[0002] Modern refrigerators typically have multiple shelves inside for storing food. These shelves are supported by shelf support strips (also called "shelf support strips") fixed to both sides of the refrigerator's inner liner. These strips have a series of slots for adjusting the depth of the shelves.

[0003] Installing the shelf assembly strips is a crucial step in the production, assembly, and after-sales service of refrigerators. Currently, the common method is to rely on the experience of operators to manually mark the positions or use simple gauges for marking. Then, the shelf assembly strips are pressed into the predetermined positions by hand and secured with screws or clips.

[0004] This traditional method has the following obvious drawbacks:

[0005] Manual marking or positioning can introduce visual and operational errors, easily leading to inconsistent installation heights of the shelf unit strips on the left and right sides, or misalignment of the slots at the front and back. This can cause the shelf unit to tilt, become uneven, or even fail to fit smoothly into the slots after placement.

[0006] Repeated measurements, marking, and comparisons are required, which takes up a long assembly time and affects overall production efficiency.

[0007] During the process of fixing the device strip, the hand pressing can easily cause displacement, resulting in a deviation between the final installation position and the intended position. Summary of the Invention

[0008] The purpose of this invention is to provide a positioning clamp device adapted to refrigerator shelf assembly strips, so as to solve the existing technical problems mentioned in the background art.

[0009] To achieve the above objectives, the present invention provides the following technical solution: a positioning clamping device adapted to a refrigerator shelf assembly strip, comprising a clamping unit, the clamping unit comprising a lower pad, a pressure plate, a group of air rods, a first horizontal groove, a second fitting groove, and an arc-shaped plastic strip. The lower pad has a first horizontal groove on both sides of its surface, and a second fitting groove is formed on the inner side of the first horizontal groove. An arc-shaped plastic strip is installed on the inner wall of the second fitting groove. A group of air rods is vertically arranged in the middle of the lower pad, and a pressure plate is installed above the group of air rods. A shelf assembly strip is engaged inside the first horizontal groove.

[0010] The fitting space formed by the first horizontal groove and the second fitting groove is used to detachably clamp and fix the shelf device strip;

[0011] The pressure plate is connected to the lower pad plate via a group of air rods, and is used to achieve precise positioning of the shelf rack strip by cooperating with a specific structure of the shelf rack strip when the shelf rack strip is clamped.

[0012] The clamping units are arranged in multiple groups horizontally, and an upper receiving box is provided in the middle of the multiple groups of clamping units. The upper receiving box has upper material gathering slopes at both ends of its inner side. The bottom of the upper receiving box is connected to a lower receiving box, and the lower receiving box has lower material gathering slopes at both ends of its inner side.

[0013] The discharge port of the lower aggregate slope is equipped with a transmission cylinder, and a spiral transmission rod assembly is installed inside the transmission cylinder. The shaft of the spiral transmission rod assembly passes through the transmission cylinder and is connected to a servo motor.

[0014] The upper and lower receiving boxes are fitted with a circulating airflow fan at their adjacent locations, and the two sets of circulating airflow fans are horizontally distributed symmetrically.

[0015] Furthermore, the inner wall shape of the fitting space is adapted to the cross-sectional profile of the shelf assembly strip.

[0016] Furthermore, side frames are installed on both sides of the upper receiving box, and side supports are vertically installed on both sides of the side frames.

[0017] Furthermore, cylinder connecting pipes are installed on both sides of the surface of the upper receiving box, and branch air pipes are connected to both sides of the cylinder connecting pipes. The branch air pipes are connected to multiple sets of air rods, and one end of the cylinder connecting pipe is connected to the main air pipe.

[0018] Furthermore, the dimensions of the arc-shaped plastic strip and the side opening of the shelf device are matched.

[0019] Furthermore, the lower pad and the pressure plate are arranged in a parallel manner.

[0020] Furthermore, the lower pad and the pressure plate are made of engineering plastic or nylon through integral injection molding.

[0021] Furthermore, the lower receiving box is interconnected with the lower material collection slope and the conveying cylinder.

[0022] Compared with the prior art, the beneficial effects of the present invention are:

[0023] 1. This invention, by setting a positioning unit (first horizontal groove and second fitting groove) that matches the specific structure of the refrigerator liner, allows one side of the shelf assembly strip to snap into the outer side of the arc-shaped plastic strip, completely eliminating errors from manual measurement and ensuring that the installation height and front-back position of the shelf assembly strips on both sides are completely consistent, thereby guaranteeing the levelness of the shelf after installation. Operation is simple; positioning is completed with a single snap-fit, greatly improving assembly efficiency.

[0024] 2. The present invention, through its symmetrical structural design, avoids operators from installing the fixtures backwards or incorrectly, thus further ensuring the stability of product quality.

[0025] 3. In cooperation with other equipment, the present invention has an upper receiving box and a lower receiving box connected to each other installed at the bottom of the fixture. When the fixture is used with the cutting device, the debris falling from the top can be recovered, so as to avoid the debris adhering to the fixture and affecting the clamping effect of the fixture.

[0026] 4. This invention is easy to mass-produce through injection molding, has low manufacturing costs, and is very suitable for promotion and use on production lines and maintenance sites. Attached Figure Description

[0036] like Figure 1-6 As shown, the present invention provides a technical solution: a positioning clamping device adapted to a refrigerator shelf assembly strip, including a clamping unit 7. The clamping unit 7 includes a lower pad 701, a pressure plate 702, a group of air rods 703, a first horizontal groove 704, a second fitting groove 705, and an arc-shaped plastic strip 706. The lower pad 701 has a first horizontal groove 704 on both sides of its surface, and a second fitting groove 705 is formed on the inner side of the first horizontal groove 704. An arc-shaped plastic strip 706 is installed on the inner wall of the second fitting groove 705. A group of air rods 703 are vertically arranged in the middle of the lower pad 701, and a pressure plate 702 is installed above the group of air rods 703. A shelf assembly strip 8 is engaged inside the first horizontal groove 704.

[0037] The fitting space formed by the first horizontal groove 704 and the second fitting groove 705 is used to detachably clamp the fixed shelf device strip 8.

[0038] The pressure plate 702 is connected to the lower pad 701 via a group of air rods 703, and is used to achieve precise positioning of the shelf device strip 8 by cooperating with the specific structure of the shelf device strip 8 when the shelf device strip 8 is clamped.

[0039] Multiple sets of clamping units 7 are arranged horizontally, and an upper receiving box 1 is provided in the middle of the multiple sets of clamping units 7. An upper material gathering slope 101 is provided at both ends of the inner side of the upper receiving box 1. A lower receiving box 11 is connected to the bottom of the upper receiving box 1, and a lower material gathering slope 1101 is provided at both ends of the inner side of the lower receiving box 11.

[0040] The discharge port of the lower material slope 1101 is equipped with a transmission cylinder 6, and a spiral transmission rod assembly 5 is installed inside the transmission cylinder 6. The shaft of the spiral transmission rod assembly 5 passes through the transmission cylinder 6 and is connected to a servo motor 3.

[0041] A circulating airflow fan 2 is fitted and installed at the adjacent positions of the upper receiving box 1 and the lower receiving box 11, and the two sets of circulating airflow fans 2 are symmetrically distributed horizontally; the inner wall shape of the fitted space is adapted to the cross-sectional profile of the shelf device strip 8; side frames 10 are installed on both sides of the upper receiving box 1, and side support columns 4 are installed vertically on both sides of the side frames 10; cylinder connecting pipes 9 are installed on both sides of the surface of the upper receiving box 1, and branch air pipes 901 are connected to both sides of the cylinder connecting pipes 9. The branch air pipes 901 are connected to multiple sets of combined air rods 703, and one end of the cylinder connecting pipes 9 is connected to the main air pipe 902; the arc-shaped plastic strip 706 and the side opening size of the shelf device strip 8 are matched; the lower pad 701 and the pressure plate 702 are arranged in parallel vertically; the lower pad 701 and the pressure plate 702 are made of engineering plastic or nylon by integral injection molding; the lower receiving box 11 is connected to the conveyor cylinder 6 through the lower material gathering slope 1101.

[0042] By setting up a positioning unit with a first horizontal groove and a second fitting groove that mates with the specific structure of the refrigerator's inner liner, one side of the shelf assembly strip 8 is engaged with the outer side of the arc-shaped plastic strip 706, completely eliminating errors from manual measurement and ensuring that the installation height and front-to-back position of the shelf assembly strips 8 on both sides are completely consistent, thereby guaranteeing the levelness of the shelf after installation. The operation is simple; positioning is completed with a single snap-fit, greatly improving assembly efficiency.

[0043] The symmetrical design prevents operators from installing the fixtures backwards or incorrectly, thus further ensuring the stability of product quality.

[0044] In coordination with other equipment, an upper receiving box 1 and a lower receiving box 11 are installed at the bottom of the fixture. When the fixture is used with the cutting device, the debris falling from the top can be recovered, preventing the debris from adhering to the fixture and affecting the clamping effect of the fixture.

[0045] It is easy to mass-produce through injection molding, has low manufacturing costs, and is very suitable for widespread use on production lines and maintenance sites.

[0046] In summary, this positioning clamping device adapted to refrigerator shelf unit strips is used in the following steps: First, during assembly, the shelf unit strip 8 is correctly slid into and clamped in the fitting space of the lower pad 701, so that the corresponding side of the shelf unit strip 8 is clamped to the outer side of the arc-shaped plastic strip 706 at the second fitting groove 705. Then, the other side of the shelf unit strip 8 is released, so that the shelf unit strip 8 is clamped into the inner side of the first horizontal groove 704, thus completing the fixation of the shelf unit strip 8. Then, the operator controls the external cylinder, thereby controlling the group of air rods 703 to descend through the sequential transmission of the main air pipe 902, the cylinder connecting pipe 9, and the branch air pipe 901, thereby pressurizing and fixing the shelf unit strip 8. After that, it can be processed with cutting equipment. After processing, the processed shelf unit strip 8 is removed from the side opening for the next operation.

[0047] It is understood that the above embodiments are merely exemplary implementations used to illustrate the principles of the present invention, and the present invention is not limited thereto.
