DETAILED DESCRIPTION

[0017] The following is a clear and complete description of the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] See also Figure 1 An embodiment of the present invention provides an automatic pre-fixing assembly device for an in-vehicle refrigerator controller, comprising: a scanning height measurement mechanism 1, a product pre-fixing mechanism 2, a top cover pressing mechanism 3, a pre-fixing traction mechanism 4, a pre-fixing return mechanism 5, and a pre-fixing limit mechanism 6, all mounted on a machine platform. The scanning height measurement mechanism detects the height of a PCBA product before assembly, performs corresponding height measurement and scanning actions on the corresponding product in a fixed position, and automatically displays the height measurement data on the screen in real time and interacts with the system after scanning, eliminating the need for human judgment and providing the result automatically. The product pre-fixing mechanism includes a product pressing block 20 for securing the PCBA product within a product slot 21 to ensure a horizontal position before the PCBA product is pressed. The pre-fixing return mechanism pushes the product pressing block away from the product slot to facilitate placement of the PCBA product. The pre-fixing traction mechanism pushes the pre-fixing traction mechanism to the pre-fixing press position. The top cover pressing mechanism presses and secures the top cover to the PCBA product. The pre-fixing limit mechanism pulls the product slot to directly below the top cover pressing mechanism.

[0019] See also Figure 2 The scanning height measurement mechanism 1 includes a bracket 11 installed on the machine, a measuring instrument 12 and a barcode scanner 13 installed on the frame. The measuring instrument's measuring point is aligned with the end of the product and the barcode scanner's vertical label in a staggered design. The flexibility of the aluminum assembly of the fasteners and the bracket ensures the relative fixation of the measuring instrument and barcode scanner and the accuracy of the measurement and scanning. The scanning height measurement mechanism is used to detect the height of the PCBA product before assembly, and sends it to the background PLC system for comparison with the set data to see if it is within the range. If it is out of range, the device alarm will remind employees that the product is warped. The barcode scanner completes the identification and scanning of the 2D label on the PCBA, automatically uploads it to the background control system, and determines the product status and whether the attached label can be printed.

[0020] See also Figure 3The product pre-fixing mechanism 2 also includes a first slide rail 201 provided on the machine platform, a product slot fixing plate 202 slidably connected to the first slide rail, a product slot 203 provided on the product slot fixing plate, and a block pushing mechanism for pushing the product block to the top of the product. Specifically, the block pushing mechanism includes a pre-pressing fixing plate 204, a spring fixing plate 205 provided on the pre-pressing fixing plate, two pushing springs 206 symmetrically provided on the spring fixing plate, a block fixing plate 207 connected to the front end of the pushing spring, and a product block 208 provided on the block fixing plate. The push spring applies thrust to the product pressing block, which can effectively pre-fix the PCBA product in the product slot, ensuring the horizontal state of the product before the PCBA product is pressed. Preferably, an in-place sensor 209 can also be provided. After the push spring automatically pushes the product pressing block into place, the product is automatically pre-pressed. The in-place sensor automatically determines whether it is in place. After the personnel removes the manual action, the height measuring mechanism is used to determine whether the product pre-pressing result is horizontal, which solves the core problem of being unable to take hands away due to the pressing of the upper shell of the product, ensures the safety of personnel and the possible scrapping problem caused by the product tilting before pressing.

[0021] Furthermore, the product trough is made of iron hibiscus material to prevent scratches on the product surface, and the product pressing block is made of stainless steel and can be recycled wirelessly, reducing the cost of manual operations and spare parts.

[0022] Specifically, the pressing block fixing plate is connected to a bearing connecting plate 210, a lifting and positioning bearing 211 is provided on the bearing connecting plate, and the bearing connecting plate is slidably connected to the machine platform through a slide rail. Figure 6 As shown, the pre-fixed homing mechanism 5 includes a jacking support rod 51 arranged on the machine platform, a jacking cylinder 52 arranged on the jacking support rod, and a jacking positioning block 53 arranged on the output end of the jacking cylinder, wherein the top surface of the jacking positioning block is a slope surface, and the pre-fixed homing mechanism also includes a first monitoring sensor 54 for detecting whether the product pressing block is in place and a second monitoring sensor 55 for detecting whether the product slot is in place. The first monitoring sensor and the second monitoring sensor are used to judge whether the mechanism is in place, and then the slope surface of the jacking positioning block is aligned with the jacking block through the fixed stroke of the jacking cylinder. The lifting and positioning bearings come into contact, and the product pressing block is moved away from the product groove to create space. After the product is placed, the lifting cylinder drops and resets, and the lifting and positioning block is separated from the lifting and positioning bearings. Under the action of the push spring, the product pressing block is clamped on the terminal of the PCBA product. The first monitoring sensor and the second monitoring sensor on both sides are used to ensure that the product groove and the product pressing block reach the specified position. At the same time, the slope surface edge of the lifting and positioning block and the sliding of the lifting and positioning bearing are used to control the engagement of the product pressing block and the PCBA product terminal, ensuring the smooth completion of product pre-fixation and the safety of personnel operation.

[0023] like Figure 4As shown, the upper cover pressing mechanism 3 includes a support rod 31 arranged on the machine table, a bottom connecting plate 32 arranged on the support rod, a triangular fixed plate 33 arranged on the bottom connecting plate, a pressing cylinder 34 arranged on the triangular fixed plate, and a pressing block 35 arranged on the output end of the pressing cylinder. The automatic pressing of the PCBA product to be pressed below is realized by fixing the stroke and speed of the pressing cylinder. Compared with manual pressing, the product can maintain the consistency of the stroke during automatic pressing, and the consistency of the pressing is ensured.

[0024] As shown in the figure, Figure 5 The pre-fixing pulling mechanism 4 includes a cylinder fixed plate 41 arranged on the machine table, a pulling cylinder 42 arranged on the cylinder fixed plate, and a pushing block 43 arranged on the output end of the pulling cylinder. The pushing block is connected with the pre-pressing fixed plate. The pulling cylinder is provided with an optical fiber sensor 44. The pulling cylinder uniformly pushes the product pre-fixing mechanism to the pre-pressing position at a constant speed. The cooperation with the optical fiber sensor ensures that the pre-pressing device reaches the specified position and maintains the action until the pre-pressing is completed. The complicated manual pulling action of the personnel is cancelled, and the efficiency is improved.

[0025] As shown in the figure, Figure 7 The pre-fixing limiting mechanism 6 includes a pulling fixed block 61, a pulling spring 62 arranged on the pulling fixed block, a retreat limiting block, and a position sensor 63. The front end of the pulling spring is connected with the product slot fixed plate. The two pulling springs cooperate with the position sensor to ensure that the pre-fixing device reaches the position below the product pressing device. The space layout of the cylinder and the electrical line is replaced, the space utilization of the equipment is improved, the situation that the product is not pressed in place due to manual pushing is avoided, and the rework probability is reduced.

[0026] The beneficial effects of the automatic pre-fixing assembly device for the vehicle-mounted refrigerator controller are as follows: the PCBA product in the product is pre-fixed and simultaneously kept in the pressing position, and the upper cover is smoothly pressed on the PCBA product. The degree of automation is high, thereby solving the problems of the inability of personnel to fix the product and efficient production, maintaining the consistency of product assembly, reducing the risk of pressing damage and product scrap cost caused by product imbalance, assisting the pre-pressing action, automatically assembling the upper and lower shells of the PCBA product, and improving the work efficiency.
