Description

Technical Field

[0001] The present invention relates to the technical field of compressors, and in particular to an angle detection device and a welding method for a connection terminal and an upper shell cover of a compressor. Background Art

[0002] The compressor's wiring terminals include a connection plate, three terminal posts mounted on the connection plate, and inserts welded to the terminal posts. When welding the wiring terminals to the corresponding positions on the compressor's upper shell cover, the operator will first manually place the wiring terminals into the corresponding through-hole positions on the upper shell cover, and then weld the wiring terminals to the upper shell cover. The relative position and angle of the terminal inserts welded on the upper shell cover must be accurate to ensure good coordination with the compressor terminals during subsequent use. Currently, since the wiring terminals can be rotated at will when placed in the welding fixture, it is easy for the terminal to be placed at an incorrect angle, resulting in an abnormal angle when the inserts are welded to the upper shell cover, which can lead to batch defects in the compressor or the scrapping of the entire machine.

[0044] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be embodied in many forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete and will fully convey the concepts of the example embodiments to those skilled in the art. Identical reference numerals in the drawings represent identical or similar structures, and thus repeated description thereof will be omitted.

[0045] Figure 1 A schematic diagram showing the correct installation of the terminal blocks on the compressor upper cover. Figure 2 The diagram shows the wiring terminals incorrectly installed on the compressor upper cover. Figure 1 and Figure 2 As shown, the terminal block 220 is provided with three terminals 221, and each terminal block 221 is welded with a plug 222. Before the terminal block 220 is welded to the upper shell cover 210 of the compressor, the terminal block 220 can rotate freely at the corresponding installation position of the upper shell cover 210. For example, the terminal block 220 can be rotated as follows Figure 1 and Figure 2 However, only when the terminal block 220 is placed Figure 1 Only when the connection terminals 220 are correctly positioned as shown can the next step of welding the connection terminals 220 to the upper housing cover 210 proceed. Otherwise, welding the connection terminals 220 to the upper housing cover 210 in the incorrect position will be considered a poor weld. Therefore, before welding the upper housing cover 210 to the connection terminals 220, it is necessary to check whether the connection terminals 220 are correctly positioned. However, there is currently no effective solution to prevent errors caused by improperly positioned connection terminals 220.

[0046] In order to solve the problem of incorrect position and angle of the terminal block installed on the upper shell cover in the prior art, an embodiment of the present invention provides an angle detection device, including: a carrier, the carrier including a bearing surface; a detection component, arranged on the bearing surface; the detection component is configured to emit and receive light signals along a preset direction to detect whether the terminal block is correctly installed on the upper shell cover of the compressor. In this technical solution, the angle detection device is used to detect whether the terminal block is correctly installed on the upper shell cover of the compressor. When the angle detection device receives the signal that the terminal block is correctly installed on the upper shell cover, the terminal block is welded to the upper shell cover as a whole. The setting of the angle detection device can reduce the welding defect rate of the terminal block due to abnormal placement position, thereby improving the welding yield of the compressor. In addition, the angle detection equipment can also perform standardized detection to improve the assembly efficiency of the compressor.

[0047] The angle detection device of the present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments shown are not intended to limit the scope of protection of the present invention.

[0048] Figure 3 FIG. 1 is a schematic diagram of an angle detection device provided by an embodiment of the present invention. Figure 3 As shown, the angle detection device includes a platform 10 and a detection assembly 30. The platform 10 includes a support surface; the detection assembly 30 is located on the support surface; and the detection assembly 30 is configured to transmit and receive optical signals along a predetermined direction to detect whether the terminal block 220 is correctly installed on the upper housing cover 210 of the compressor.

[0049] like Figure 3 As shown, before testing, the upper shell cover 210 and the connection terminals 220 of the compressor need to be assembled (but not welded) and placed on the supporting surface of the carrier 10.

[0050] Furthermore, in some embodiments, the detection component 30 is a photoelectric sensor that converts changes in optical signals into changes in electrical signals. In some embodiments, the photoelectric sensor can be an active infrared sensor that emits infrared light signals, but is not limited thereto and can also be other photoelectric sensors known in the art.

[0051] Specifically, such as Figure 3 As shown, the photoelectric sensor includes an emitter 31 and a receiver 32, which are arranged opposite each other. The emitter 31 is used to emit a light beam, and the receiver 32 is used to receive the light signal and convert it into an electrical signal. The arrangement of the emitter 31 and receiver 32 is merely illustrative and is not intended to be limiting.

[0052] Further, if Figure 3As described above, the angle detection device further includes a bracket 20 disposed on the supporting surface, and the transmitter 31 is connected to the bracket 20 .

[0053] Specifically, the bracket 20 includes a base 21, a first support arm 22 and a second support arm 23, the first end of the first support arm 22 is connected to the base 21, the first end of the second support arm 23 is connected to the second end of the first support arm 22, and the second end of the second support arm 23 is connected to the transmitter 31.

[0054] Furthermore, in some embodiments, the first support arm 22 is rotatably connected to the base 21 about a first direction via a first drive component. The first direction is defined as the vertical direction as viewed on paper. The rotational motion of the first support arm 22, driven by the first drive component, adjusts the position of the transmitter 31 accordingly, thereby enabling the detection assembly 30 to detect a variety of compressor models, broadening the applicability of the angle detection device, and facilitating standardized detection of whether the terminal block 220 is installed at the correct angle on the upper housing cover 210, thereby improving compressor assembly efficiency.

[0055] Furthermore, in some embodiments, the first driving component includes a rotating shaft, a first end of which is rotatably connected to the base 21, and a second end of which is connected to the first support arm 22. Rotation of the rotating shaft drives the first support arm 22, which in turn drives the transmitter 31 to rotate a corresponding angle, allowing the transmitter 31 to move to a suitable position to detect the angle of the terminal block 220 on the upper housing cover 210. Exemplarily, the component driving the rotating shaft can be a rotary motor.

[0056] Furthermore, in some embodiments, the first support arm 22 is movably connected to the second support arm 23 along the first direction and / or the second direction via a second driving component. The second direction is the left-right direction as viewed from the paper or the front-back direction as viewed from the paper. The provision of the second driving component enables the second support arm 23 to move in the left-right direction as viewed from the paper or the front-back direction as viewed from the paper, thereby causing the transmitter 31 to be raised or lowered, adjusted forward or backward, left or right accordingly, thereby enabling the detection component 30 to be applicable to detecting whether the position of the terminal 220 on the upper shell cover 210 of various models is correctly placed, thereby increasing the range of compressor models that can be detected by the angle detection device, realizing standardized detection, and improving the assembly efficiency of the compressor.

[0057] Furthermore, in some embodiments, the second driving component may be a linear motor, a lead screw, or a cylinder, etc., which can drive the second support arm 23 to perform linear motion.

[0058] In other embodiments, the receiver 32 may also be provided with a corresponding moving device to drive the receiver 32 to move, so that when the position of the transmitter 31 changes, the receiver 32 can still normally receive the transmission signal.

[0059] Furthermore, in some embodiments, the angle detection device also includes a control unit (not shown in the figure) for controlling the operation of the first drive component and the second drive component to adjust the position of the transmitter 31 to adapt to the angle detection of the position of the terminal 221 on the detected compressor model.

[0060] Furthermore, an embodiment of the present invention also provides a method for welding a connection terminal and an upper shell cover of a compressor. Figure 4 The figure shows a method for welding the connection terminal and the upper shell cover of a compressor provided by an embodiment of the present invention. Figure 4 As shown, the following steps are included:

[0061] Step S100: providing a terminal block and an upper shell cover of a compressor, wherein the upper shell cover is provided with a through hole, the terminal block comprising a connection plate, three terminals located on the connection plate, and inserts welded to the terminals; placing the terminal block in a first position of the through hole;

[0062] Step S200: using the angle detection device as described above to detect whether the angle of at least one of the terminal or the plug is correctly installed with the upper cover;

[0063] Step S300: If yes, the welding equipment is started to weld the terminal block and the upper shell cover into one piece;

[0064] Step S400: If not, the welding device is turned off, and the terminal is adjusted to the second position of the through hole, and then the angle of at least one of the terminal post or the insert and the upper shell cover is detected to see if they are correctly installed.

[0065] The following will be combined Figures 1 to 6 The process of the welding method of the compressor terminal and the upper shell cover is specifically described.

[0066] refer to Figures 1 to 4 Step S100: Provide a terminal block 220 and an upper shell cover 210 of the compressor. The upper shell cover 210 is provided with a through hole. The terminal block 220 includes a connecting plate, three terminal blocks 221 located on the connecting plate, and a plug 222 welded to the terminal blocks 221. Place the terminal block 220 in the first position of the through hole.

[0067] When the terminal block 220 is placed at different positions of the through hole, the three terminals 221 form different angles with two reference points (such as the center of the upper shell cover 210 and the center of the terminal block 220) whose positions remain unchanged. Figure 1 and Figure 2 .

[0068] Step S200 : using the above angle detection device to detect whether the angle of installation of at least one terminal 221 or the plug 222 and the upper housing cover 210 is correct.

[0069] The specific detection steps can be:

[0070] The detection component transmits a signal;

[0071] When the detection component does not receive a signal continuously within the preset angle, the angle of the wiring terminal and the upper shell cover is correctly installed.

[0072] The detection component in the embodiment of the present invention is, for example, a photoelectric sensor. Figure 5 As shown, when the angle of the insert 222 is correctly placed, the emitter 31 of the photoelectric sensor is at a preset angle ( Figure 5 The photoelectric sensor's receiver 32 transmits a signal within the angle between the preset angle ( Figure 5 No signal is received continuously within the angle between the dotted lines shown.

[0073] like Figure 6 As shown, when the insert 222 is not placed at the correct angle, the emitter 31 of the photoelectric sensor is at the preset angle ( Figure 6 The angle of the dotted line shown in FIG), the receiver 32 of the photoelectric sensor is at a preset angle ( Figure 6 The photoelectric signal may not be received at certain angles within the angle indicated by the dashed line (shown), thus determining that the angle of insertion piece 222 is incorrectly positioned. Therefore, the transmitter 31 of the photoelectric sensor can be adjusted to continuously transmit optical signals within a certain angle. If the receiver 32 continuously fails to receive the optical signal from the transmitter 31 within this angle, it indicates that the position of the insertion piece 222 is correctly positioned. Conversely, if the receiver 32 can at least receive the optical signal from the transmitter 31 within the preset continuous angle, it indicates that the position of the insertion piece 222 is incorrect, prompting the operator to check the position of the terminal block 220 and adjust it to the correct position.

[0074] It should be noted that the relative positions of the three plugs 222 on the terminal block 220 are fixed. Therefore, it is only necessary to check whether the position of one plug 222 is correctly placed before proceeding to the next step. There is no need to check all three plugs 222, which saves detection time.

[0075] It should also be noted that the detection component can also be used to detect whether the installation angle of at least one terminal 221 and the upper shell cover 210 is correct within a preset angle. The principle is the same as that of the plug 222 detection, which will not be repeated here.

[0076] The detection strategy for the angle detection device to detect whether the placement position of the connection terminal 220 is correct is not limited to the above-mentioned example strategy, and no specific limitation is made here.

[0077] Step S300: If it is detected that the angle of at least one terminal 221 or the insert 222 is correctly installed with respect to the upper cover 210, the welding device is started to weld the terminal 220 and the upper cover 210 into one body;

[0078] Step S400: If it is detected that the angle of installation of at least one terminal 221 or plug 222 with the upper shell cover 210 is incorrect, the welding equipment is turned off, and the terminal 220 is adjusted to the second position of the through hole, and then the process returns to step S200 to use the above angle detection device to detect whether the angle of installation of at least one terminal 221 or plug 222 with the upper shell cover 210 is correct.

[0079] The operations for adjusting the position of the terminal block 220 include axial rotation, tilting, and translation. By transmitting a signal indicating whether the terminal block 220 is correctly installed, detected by the angle detection device, to the welding device, the welding device starts welding when it receives the signal indicating that the terminal block 220 is correctly positioned; otherwise, it fails to start welding when it receives the signal indicating that the terminal block 220 is incorrectly positioned, thereby reducing the rate of abnormal welding angles of the terminal block 220.

[0080] In summary, the angle detection device provided by the present invention has the following advantages:

[0081] An angle detection device is used to detect whether the terminal block is correctly installed on the upper shell cover of the compressor. When the angle detection device detects that the terminal block is correctly installed on the upper shell cover, the terminal block and the upper shell cover are welded together to reduce poor welding caused by abnormal placement of the terminal block and improve the welding yield of the compressor.

[0082] The above is a further detailed description of the present invention in conjunction with specific preferred embodiments, and the specific implementation of the present invention should not be considered to be limited to these descriptions. For those skilled in the art of the present invention, without departing from the concept of the present invention, several simple deductions or substitutions can be made, which should be considered to fall within the scope of protection of the present invention.
