Description

Technical Field

[0001] This utility model relates to the field of chip mounting equipment technology, and in particular to a solar cell chip mounting machine. Background Technology

[0002] Existing chip mounters typically control the mounting force indirectly through preset pressure thresholds or displacement sensors when mounting solar cells. However, due to fluctuations in solar cell thickness and substrate elasticity, traditional rigid mounting heads are prone to the following problems: insufficient mounting force results in incomplete cell adhesion, leading to poor soldering or detachment; excessive mounting force causes stress concentration and damage to the solar cell or substrate; and relying on a single sensor for feedback makes it difficult to simultaneously detect the mounting completion status in real time. Therefore, there is an urgent need for a device that can dynamically adjust the mounting force and simultaneously detect the mounting completion status. Utility Model Content

[0003] The technical problem to be solved by this utility model is: in order to overcome the following problems that are easily caused by rigidly installed mounting heads in the prior art: when the mounting force is insufficient, the solar cell is not fully attached, resulting in poor soldering or detachment; when the mounting force is too large, the solar cell or substrate is damaged due to stress concentration; and the problem that it is difficult to synchronously detect the mounting completion status in real time by relying on a single sensor feedback, a solar cell mounting machine is provided.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a solar cell chip mounting machine, including a base, a mounting mechanism, a driving mechanism, and a fixing mechanism. The driving mechanism is fixedly connected to the base, and the output end of the driving mechanism is drivenly connected to the mounting mechanism. The driving mechanism is used to provide power for the movement of the mounting mechanism, which is used to mount solar cells.

The moving contact is fixedly connected to the bottom surface of the mounting base, and the fixed contact is fixedly connected to the base. The control accuracy can be improved by the mounting base supported by the elastic support element and the sensing of the fixed and moving contacts. Moreover, the contact point serves as a dual judgment basis, thereby detecting whether the force is up to standard and the displacement is in place, avoiding false detection.

[0005] The device further includes a drive mechanism comprising a lateral movement component and a longitudinal movement component. The longitudinal movement component includes a longitudinal drive member, a longitudinal slide rail, and a longitudinal slider that matches the longitudinal slide rail.

The lateral slide rail and the longitudinal slider are fixedly connected. The lateral drive and the longitudinal slider are fixedly connected.

[0007] To address the inconvenience of pick-up and placement in the placement mechanism, the placement mechanism further includes a placement nozzle and a lifting drive. The lifting drive is connected to the output end of the drive mechanism, and the output end of the lifting drive is fixedly connected to the placement nozzle, which is used to pick up the placement.

The width of the discharge port is greater than the width of the workbench, and the discharge port is used for the battery cells to pass through.

[0009] To address the issue of inconvenience in removing battery cells after they are attached to the workbench surface, a push-out port is further provided on the left side of the mounting base, with the width of the push-out port being smaller than the width of the workbench.

[0010] To address the issue of inconvenience in removing battery cells after they are bonded to the worktable surface, the bonding mechanism further includes an unloading mechanism, which is fixedly connected to a base. The unloading mechanism is used to push the battery cells away from the worktable.

[0011] The unloading mechanism further includes an unloading cylinder and an unloading push plate. The unloading cylinder is arranged on the base, and the output end of the unloading cylinder is fixedly connected to the unloading push plate.

[0012] To solve the problem of jamming between the unloading push plate and the worktable, the bottom surface of the unloading push plate is further provided with an arc-shaped guide surface at the end near the worktable.

[0020] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0021] like Figure 1 This is a schematic diagram of the structure of this utility model, a solar cell chip mounting machine, including a base 1, a mounting mechanism 2, a driving mechanism 3, and a fixing mechanism 4. The driving mechanism 3 is fixedly connected to the base 1, and its output end is drively connected to the mounting mechanism 2. The driving mechanism 3 provides power for the movement of the mounting mechanism 2, which is used to mount solar cells.

The moving contact 44 is fixedly connected to the bottom surface of the mounting base 42, and the fixed contact 45 is fixedly connected to the base 1. The mounting base 42 supported by the elastic support element 43 and the sensing of the fixed contact 45 and the moving contact 44 can improve control accuracy. Moreover, the contact point serves as a dual judgment criterion, thereby detecting whether the force meets the standard and the displacement is in place, avoiding false detection. The fixing mechanism 4 includes a guide telescopic rod 46. One end of the guide telescopic rod 46 is fixedly connected to the mounting base 42, and the other end is fixedly connected to the base 1. The guide telescopic rod 46 includes an outer tube and an inner rod, and has telescopic properties. The guide telescopic rod 46 can be used to provide stable support to ensure that the equipment maintains balance and stability during operation.

[0022] like Figure 1 , 2 As shown, the drive mechanism 3 includes a lateral movement component and a longitudinal movement component. The longitudinal movement component includes a longitudinal drive member 31, a longitudinal slide rail 32, and a longitudinal slider 33 that matches the longitudinal slide rail 32. The longitudinal slide rail 32 is fixedly connected to the base 1, the longitudinal slide rail 32 is fixedly connected to the longitudinal slider 33, and the longitudinal drive member 31 is fixedly connected to the base 1. The longitudinal drive member 31 is used to provide power for the movement of the longitudinal slider 33. The longitudinal drive member 31 can be a cylinder, an electric push rod, or a lead screw mechanism driven by a motor, etc. This application does not specifically limit this.

[0023] The lateral movement assembly includes a lateral drive 34, a lateral slide rail 35, and a lateral slider 36 that matches the lateral slide rail 35. The lateral slide rail 35 and the longitudinal slider 33 are fixedly connected, the lateral slide rail 35 and the lateral slider 36 are fixedly connected, the lateral drive 34 and the longitudinal slider 33 are fixedly connected, the lateral drive 34 is used to provide power for the movement of the lateral slider 36, and the lateral slider 36 is fixedly connected to the patch mechanism 2. The lateral drive 34 can be a cylinder, an electric actuator, or a lead screw mechanism driven by a motor, etc. This application does not specifically limit this aspect.

[0024] like Figure 1 , 2 As shown, the patch assembly mechanism 2 includes a patch nozzle 21 and a lifting drive. The lifting drive is connected to the output end of the drive mechanism 3. The output end of the lifting drive is fixedly connected to the patch nozzle 21. The patch nozzle 21 is used to pick up patches. The lifting drive can be a cylinder, an electric actuator, or a lead screw mechanism driven by a motor, etc. This application does not make specific limitations on this.

[0025] like Figure 2 As shown, a discharge port 421 is provided on the right side of the mounting base 42. The width of the discharge port 421 is greater than the width of the workbench 41. The discharge port 421 is used for the battery cells to pass through.

[0026] like Figure 2 As shown, a pusher port 422 is provided on the left side of the mounting base 42. The width of the pusher port 422 is smaller than the width of the workbench 41. The pusher port 422 is used for the unloading pusher plate 52 to pass through.

[0027] like Figure 2 , 3 As shown, the mounting mechanism 2 includes an unloading mechanism 5, which is fixedly connected to the base 1. The unloading mechanism 5 is used to push the battery cells away from the worktable 41.

[0028] The unloading mechanism 5 includes an unloading cylinder 51 and an unloading push plate 52. The unloading cylinder 51 is arranged on the base 1, and the output end of the unloading cylinder 51 is fixedly connected to the unloading push plate 52. The bottom surface of the unloading push plate 52 has an arc-shaped guide surface 521 on the end near the worktable 41. When the guide surface 521 contacts the worktable 41, the elasticity of the mounting base 42 and the planar limitation of the guide telescopic rod 46 on the mounting base 42 can be used to push only the battery cell and avoid the unloading push plate 52 and the worktable 41 from getting stuck.

[0029] In use, the battery cell is placed on the worktable 41. The drive mechanism 3 drives the mounting mechanism 2 to move. After the mounting mechanism 2 picks up the battery cell, the drive mechanism 3 drives it to move above the worktable 41. The lifting drive is activated, causing the mounting nozzle 21 to descend. The battery cell on the mounting nozzle 21 contacts the battery cell, that is, the mounting nozzle 21 presses against the battery cell. During the descent of the mounting base 42, the elastic support element 43 controls the mounting force until the moving contact 44 and the fixed contact 45 contact, sending a signal that the mounting is complete. The activation of the lifting drive and the drive mechanism 3 controls the mounting nozzle 21 to reset. The mounting base 42 resets under the elastic force of the elastic support element 43. The unloading cylinder 51 is activated, causing the unloading push plate 52 to move and contact the battery cell after passing through the push port 422, thereby pushing the battery cell so that the right end of the battery cell passes through the unloading port 421. At this time, the right end of the battery cell protrudes from the worktable 41, making it easy for the user to pick it up.

[0030] The bonding force is controlled by the elastic coefficient of the elastic support element 43 and the spacing between the moving contact 44 and the fixed contact 45, thus avoiding interference from other factors.

[0031] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
