Description

Technical Field

[0001] This invention relates to a refrigeration unit production equipment, and more specifically, to a refrigeration unit testing and adhesive scraping device. Background Technology

[0002] Currently, the thermal grease printing process for refrigeration units is entirely manual, involving rolling and applying the grease. Controlling the application amount is difficult, and there is a lack of corresponding solutions and equipment both domestically and internationally. Given the diverse specifications of unit products, assembly processes, assembly quality, assembly efficiency, and assembly stability all face significant challenges. The production process of refrigeration units requires the inspection of insulation gaskets, but existing inspection methods struggle to inspect deep holes, leading to frequent misjudgments. Traditional production methods separate thermal grease printing and insulation gasket inspection, increasing handling steps, reducing production efficiency, and raising production costs. Summary of the Invention

[0003] To overcome the above shortcomings, the present invention provides a refrigeration unit testing and adhesive scraping device, which sets up the thermal grease printing and heat insulation gasket testing of the refrigeration unit on the same frame for operation, which can improve production efficiency and reduce costs; moreover, it can achieve reliable and accurate testing of deep holes.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a refrigeration unit detection and adhesive scraping device, comprising a frame, on which are mounted:

[0005] The clamping mechanism includes a positioning block, which presses against the refrigeration unit to position the refrigeration unit.

[0006] The detection unit includes a detection rod and a sensor. A detection hole is provided on the cooling unit. The detection rod can be raised and lowered. The upper end of the detection rod abuts the bottom of the detection hole. The sensor detects the detection rod.

[0007] The glue scraping unit includes a glue scraping screen, which is attached to the cooling unit.

[0008] During the refrigeration unit testing and adhesive scraping operation, the refrigeration unit is loaded onto the loading position on the frame. The detection hole on the refrigeration unit is aligned with the detection rod, and the detection rod is inserted into the detection hole, with the upper end of the detection rod abutting against the bottom of the detection hole. Then, the positioning block on the clamping mechanism presses the refrigeration unit into place. The printed surface on the refrigeration unit is then wiped clean to ensure it is free of stains and foreign matter. The device is then started, and the sensor detects the detection rod. The heat insulation gasket of the refrigeration unit needs to be installed inside the detection hole. If the heat insulation gasket is already installed inside the detection hole, the depth of the detection hole will decrease, and the length of the detection rod extending downwards from the detection hole will increase. If the sensor detects the detection rod at this point, it indicates that the heat insulation gasket has been installed.

[0009] After the detection of the heat insulation gasket is completed, install the squeegee screen plate in place, place the thermal grease on the squeegee screen plate, and scrape the thermal grease with a squeegee to print the thermal grease onto the surface of the refrigeration unit. After completion, remove the squeegee screen plate, unlock the clamping mechanism, and remove the refrigeration unit from the rack.

[0010] This refrigeration unit detection and squeegee device of the present application operates the printing of the thermal grease and the detection of the heat insulation gasket of the refrigeration unit on the same rack, which can improve production efficiency and reduce costs; moreover, it can achieve reliable detection of deep holes and accurate detection.

[0011] Preferably, a positioning spring is sleeved on the detection rod, a limiting head is provided on the detection rod, and the positioning spring and the limiting head respectively abut against both sides of the rack.

[0012] The positioning spring positions the detection rod so that the upper end of the detection rod always abuts against the bottom of the detection hole. The limiting head limits the detection rod to prevent the detection rod from disengaging from the rack.

[0013] Preferably, a connecting seat is correspondingly installed on the rack and the detection rod, and the positioning spring and the limiting head respectively abut against both ends of the connecting seat.

[0014] The setting of the connecting seat facilitates the installation of the detection rod.

[0015] Preferably, two sensors are correspondingly installed at the lower end of the detection rod, the two sensors are arranged up and down, a detection groove is provided on the sensor, and the lower end of the detection rod can be inserted into the detection groove.

[0016] The heat insulation gasket is connected to the bottom surface of the detection hole by screws. Only when both the heat insulation gasket and the screws are installed in place can the detection be considered qualified. When neither the heat insulation gasket nor the screws are installed at the bottom of the detection hole, neither of the two sensors can sense the detection rod. When only the heat insulation gasket or the screws are installed at the bottom of the detection hole, the upper sensor can sense the detection rod, while the lower sensor cannot sense the detection rod. When both the heat insulation gasket and the screws are installed in place at the bottom of the detection hole, both sensors can sense the detection rod. By setting two sensors, the installation condition of the heat insulation gasket in the detection hole on the refrigeration unit can be accurately detected.

[0017] Preferably, a positioning frame is detachably installed on the rack, and the squeegee screen plate is installed on the positioning frame.

[0018] The setting of the positioning frame facilitates the installation of the squeegee screen plate. The positioning frame is detachably arranged. When installing and removing the refrigeration unit, remove the positioning frame to avoid interference.

[0019] Preferably, a controller, an indicator light and an alarm are installed on the rack, and the sensor, the indicator light and the alarm are all electrically connected to the controller.

[0020] The data detected by the sensor is transmitted to the controller. When the sensor detects that the heat insulation pad is installed in place, the indicator light illuminates; when it detects that the pad is not installed in place, the alarm sounds to alert the operator to check.

[0021] Preferably, the clamping mechanism also includes a U-shaped positioning frame, with connecting columns that can rotate outwards installed at both ends of the positioning frame, a positioning block connected to the upper part of the connecting columns, and a tension spring connected between the connecting columns and the positioning frame.

[0022] The positioning block is installed on the connecting column, which can rotate and is positioned by a tension spring. During the installation of the refrigeration unit, it moves downward, pushing the connecting column to rotate. After it moves into place, the connecting column returns to its original position under the action of the tension spring, causing the positioning block to press against the refrigeration unit, thus positioning the refrigeration unit. When the refrigeration unit is removed in one direction, the connecting column is pushed to rotate, causing the positioning block to separate from the refrigeration unit, making it easier to remove the refrigeration unit upward.

[0023] Preferably, a pin is installed on the positioning frame, the lower part of the connecting column is rotatably connected to the pin, a locking groove is provided on the connecting column, and a locking pin is provided on the positioning frame corresponding to the locking groove, with the locking pin abutting against the bottom of the locking groove.

[0024] The tension spring applies tension to the lower end of the connecting column, causing the bottom of the locking groove on the connecting column to abut against the locking pin, thus positioning the positioning block. At this time, the positioning block presses against the refrigeration unit.

[0025] Preferably, the positioning block is provided with an inclined guide surface.

[0026] During the installation of the refrigeration unit, the positioning block is pushed outward by the guide surface.

[0027] Preferably, a drive sleeve is mounted on the frame, and a driven sleeve is movably mounted on the detection rod. The detection rod and the driven sleeve are circumferentially locked. The drive sleeve and the driven sleeve are connected by a transmission mechanism. A drive rod is mounted inside the drive sleeve and extends upward. A spiral groove is provided on the outer wall of the drive rod, and a guide post is provided on the inner wall of the drive sleeve. The end of the guide post is inserted into the spiral groove. During the process of clamping the refrigeration unit onto the frame, the drive rod is pushed downward. The movement of the drive rod causes the drive sleeve to rotate, thereby causing the driven sleeve and the detection rod to rotate.

[0028] During the loading of the cooling unit onto the frame, the cooling unit presses against the drive rod, pushing the drive rod downwards, which in turn rotates the detection rod as it inserts into the detection hole. If the cooling unit's position deviates during installation, the rotation of the detection rod prevents it from getting stuck in a certain position within the detection hole, ensuring that the end of the detection rod rests against the bottom of the detection hole after the cooling unit is properly installed, thus guaranteeing the accuracy of the test data.

[0029] Compared with the prior art, the beneficial effects of the present invention are: (1) The refrigeration unit detection and scraping device of this application sets the thermal grease printing and heat insulation gasket detection of the refrigeration unit on the same frame for operation, eliminating the handling process, improving production efficiency and reducing costs; (2) The detection rod is used for detection, and the position of the detection rod is sensed by the sensor, thereby realizing reliable detection of deep holes and accurate detection; (3) By setting two sensors, the installation status of the heat insulation gasket in the detection hole on the refrigeration unit can be accurately detected; (4) When the position of the refrigeration unit deviates to a certain extent during the installation process, the rotation of the detection rod can prevent the detection rod from getting stuck in a certain position of the detection hole, ensuring that after the refrigeration unit is installed in place, the end of the detection rod is against the bottom of the detection hole, thereby ensuring the accuracy of the detection data.

[0035] The technical solution of the present invention will be further described in detail below through specific embodiments and in conjunction with the accompanying drawings:

[0036] Example 1: A refrigeration unit detection and adhesive scraping device (see attached) Figure 1 To be continued Figure 3 ), including rack 1, on which are mounted:

[0037] The clamping mechanism includes a positioning block 2, which presses against the refrigeration unit 3 to position the refrigeration unit.

[0038] The detection unit includes a detection rod 4 and a sensor 5. The sensor is a photoelectric switch. A detection hole is provided on the cooling unit. The detection rod can be raised and lowered. The upper end of the detection rod abuts the bottom of the detection hole. The sensor detects the detection rod.

[0039] The glue scraping unit includes a glue scraping screen 6, which is bonded to the cooling unit.

[0040] A positioning spring 7 is fitted onto the detection rod, and a limiting head 8 is provided on the detection rod. The positioning spring and the limiting head abut against both sides of the frame. A stepped surface is provided on the detection rod, and the positioning spring abuts against the stepped surface. A connecting seat 9 is installed on the frame corresponding to the detection rod, and the detection rod is movably connected to the connecting seat. The positioning spring and the limiting head abut against both ends of the connecting seat. In this embodiment, four detection rods are provided, and two sensors are installed at the lower end of each detection rod. The two sensors are arranged one above the other, and a detection groove 10 is provided on the sensor. The lower end of the detection rod can be inserted into the detection groove.

[0041] A positioning frame 11 is detachably mounted on the frame, and a scraper mesh is installed on the positioning frame. Several uprights 12 are installed on the frame corresponding to the positioning frame, and the positioning frame and uprights are detachably connected. A heat-conducting block 13 is installed on the upper part of the refrigeration unit, and the scraper mesh has corresponding mesh holes. A controller, indicator lights 14, and an alarm 15 are installed on the frame, and the sensor, indicator lights, and alarm are all electrically connected to the controller.

[0042] The clamping mechanism also includes a U-shaped positioning frame 16. A connecting screw 17 is installed between the positioning frame and the frame, and three locking nuts 18 are connected to the connecting screw. One locking nut abuts against the frame, and the other two locking nuts abut against the upper and lower surfaces of the positioning frame, respectively. This structure allows adjustment of the installation height of the positioning frame to accommodate refrigeration units of different sizes. Two lifting guide rods 19 are installed on the frame, and the lifting guide rods are movably connected to the positioning frame. Both ends of the positioning frame are equipped with outwardly rotatable connecting columns 20. A positioning block is connected to the upper part of the connecting column, and a tension spring 21 connects the connecting column and the positioning frame. A pin 22 is installed on the positioning frame, and the lower part of the connecting column is rotatably connected to the pin. A locking groove 23 is provided on the connecting column, and a locking pin 24 is provided on the positioning frame corresponding to the locking groove, with the locking pin abutting against the bottom of the locking groove. An inclined guide surface 25 is provided on the positioning block.

[0043] During the refrigeration unit testing and adhesive scraping operation, the refrigeration unit is loaded onto the loading position on the frame. The detection hole on the refrigeration unit is aligned with the detection rod, and the detection rod is inserted into the detection hole, with the upper end of the detection rod abutting the bottom of the detection hole. Then, the positioning block on the clamping mechanism presses the refrigeration unit into place. The printed surface on the refrigeration unit is then wiped clean to ensure it is free of stains and foreign matter. The device is then started, and the sensors detect the detection rod. The heat insulation gasket of the refrigeration unit needs to be installed inside the detection hole. If the heat insulation gasket is already installed inside the detection hole, the depth of the detection hole will decrease, and the length of the detection rod extending downwards from the detection hole will increase. If both sensors corresponding to the same detection rod detect the rod, it indicates that the heat insulation gasket and screws are properly installed.

[0044] After the insulation gasket is inspected, install the grease scraper in place, place the thermal grease on the grease scraper, and use the scraper 26 to scrape the thermal grease onto the surface of the refrigeration unit. After completion, remove the grease scraper, unlock the clamping mechanism, and remove the refrigeration unit from the frame.

[0045] Example 2: A refrigeration unit detection and adhesive scraping device (see attached) Figure 4 Its structure is similar to that of Embodiment 1, with the main difference being that in this embodiment, a drive sleeve 27 is installed on the frame, and a driven sleeve 28 is movably mounted on the detection rod. The detection rod and the driven sleeve are circumferentially locked. The connecting seat includes a fixed seat 29 and a driven sleeve. The fixed seat is securely mounted on the frame, and the driven sleeve is rotatably mounted on the frame. A positioning spring abuts against the fixed seat, and a limiting head abuts against the lower end of the driven sleeve. The drive sleeve and the driven sleeve are connected by a transmission. A driven gear ring is provided on the outer wall of the driven sleeve, and a driving gear ring is provided on the outer wall of the drive sleeve. All driven gear rings mesh with the driving gear ring for transmission. An avoidance notch 30 is provided on the outer wall of the fixed seat, and the edge of the driving gear ring passes through the avoidance notch and meshes with the driven gear ring. A drive rod 31 is fitted inside the drive sleeve, extending upwards. A spiral groove 32 is provided on the outer wall of the drive rod, and a guide post 33 is provided on the inner wall of the drive sleeve, with its end inserted into the spiral groove. An anti-rotation guide sleeve 34 is installed on the frame, with a protrusion 35 on its inner wall. An axially arranged groove 36 is provided on the outer wall of the drive rod, and the protrusion and groove are fitted together to achieve circumferential locking of the drive rod. During the process of clamping the refrigeration unit onto the frame, the drive rod is pushed downwards. The movement of the drive rod causes the drive sleeve to rotate, thereby causing the driven sleeve and the detection rod to rotate. Other structures are the same as in Embodiment 1.

[0046] During the loading of the cooling unit onto the frame, the cooling unit presses against the drive rod, pushing the drive rod downwards, which in turn rotates the detection rod as it inserts into the detection hole. If the cooling unit's position deviates during installation, the rotation of the detection rod prevents it from getting stuck in a certain position within the detection hole, ensuring that the end of the detection rod rests against the bottom of the detection hole after the cooling unit is properly installed, thus guaranteeing the accuracy of the test data.
